Can organs from a donor who had COVID-19 be used for transplants?
Because of the possibility of passing COVID-19 to the organ recipient, organs from patients with COVID-19 cannot be used for transplants.
Is there data that show people with better lung capacity (e.g., runners, swimmers, bicyclists) fare better if exposed to COVID-19?
Data has shown that high-risk populations (people over age 60 and those with underlying medical conditions, such as chronic heart and lung disease and diabetes) are more likely to progress to severe disease after exposure to COVID-19 than younger people without underlying medical problems. It is not known if athletes would have better outcomes from COVID-19.
Can mosquitoes can carry COVID-19 by biting an infected person and then biting someone else?
There is no evidence that it is transmitted through mosquitoes. The primary form of transmission is through droplets generated when infected people cough or sneeze or through droplets of discharge from the nose. To prevent the spread of the infection, frequently wash hands thoroughly and avoid close contact with anyone who is coughing or sneezing.
Are older CPAP machines of any use to medical facilities as ventilators during the COVID-19 pandemic?
CPAP machines are useful for the treatment of conditions such as obstructive sleep apnea; however, they are not a substitute for ventilators that are needed to treat people with severe COVID-19 infection.
I believe I had COVID-19 in January. How can I get my plasma tested for antibodies, and is it worth doing?
Antibody tests to determine if you have been previously infected are not yet commercially available, but they are in development. We do not know yet if prior infection will lead to long-lasting protection against future infection, but if that turns out to be true, then it may become important in the future for people to know their status.
I am a 64-year-old woman who had pneumonia four years ago that caused heart failure. I am healthy now. Am I at a lower risk of contracting COVID-19 if I have had both pneumonia shots?
The pneumonia shots, Pneumovax and Prevnar, are vaccines that help protect patients against pneumonia caused by certain bacteria. It does not provide any protection against viral infections such as COVID-19.
I have Multiple Sclerosis, which causes body aches all the time and fatigue — sometimes even an elevated body temp like 99.9. I also have chills and shortness of breath. How do I know the difference if I was to contract COVID-19?
The key is to note any symptoms that are outside of normal for you. If you develop any new or worsening symptoms you should discuss with your primary care provider to decide the next steps. The main symptoms of COVID-19 are cough, shortness of breath and fever. However, additional symptoms could include any, or none, of the following: loss of sense of taste and smell, fatigue, muscle aches, sore throat, headache or diarrhea.
I have a relative who is sick with a fever between 101-104, and she can't be tested until April 1. What is she supposed to do until then? What if her breathing gets worse?
Any person with fever, cough or shortness of breath should be aware that these symptoms could be from COVID-19. Any person with these symptoms should discuss with their primary care provider to decide the next steps. While waiting for testing, it is advisable to stay at home in self-isolation (see link here). Any person who begins to develop worsening symptoms, including new chest pain not related to cough, worsening shortness of breath, confusion, bluish discoloration to the lips or coughing up blood should seek immediate medical attention.
How can anyone say that the COVID-19 pandemic is "leveling off" when people haven’t been tested?
At this time, there is no evidence that the numbers of people testing positive for COVID-19 is leveling off. In fact, the pandemic is continuing to accelerate quickly across most of the country. On Thursday, the United States became the country with the highest number of confirmed COVID-19 cases.
We are not supposed to touch our eyes. Could you explain why? I wear contact lenses and I put them in every morning and take them out every night. I wash my hands thoroughly several times a day.
We know that infection occurs through close contact with respiratory droplets from others who are ill. We also know that infection may occur through contact with contaminated surfaces. When a person touches their face (and their eyes) after coming into contact with the virus, there is a chance of developing illness. Thus, we would recommend washing hands frequently throughout the day. This includes washing hands prior to putting contacts in and taking them out.
Can a person be infected again with COVID-19 after recovering?
There were some early reports in Japan and China of people becoming re-infected with COVID-19, but there is not enough data to see if this is really the case. Once a person recovers from illness, there is evidence that some immunity to the virus forms. It remains unclear if this immunity grants full protection from infection after re-exposure.
What is the risk of getting COVID-19 from ordering take-out food or going through a drive-thru? Should these be avoided and used only as a last resort?
Infection is unlikely to occur in this way. We know that infection occurs through close contact with others who are ill, specifically through contact with respiratory droplets. Infection may also spread through contact with contaminated surfaces as well. We recommend frequently washing your hands, especially after contact with food containers and packaging in order to minimize the chances of acquiring infection.
Is it necessary for a senior living alone to continually wash and sanitize hands?
To protect yourself, it is recommended that you clean frequently touched surfaces and frequently wash your hands throughout the day especially after you have been in a public place, after blowing your nose, coughing or sneezing.
At what point or stage is COVID-19 detectable? Does a person have to wait for symptoms? It seems waiting that long is not the best thing for the public.
With the tests currently available, it may be possible to detect the virus up to 48 hours before a person begins to develop symptoms. The problem is that testing an asymptomatic person today does not mean that they will not develop infection later. It is important to test who is the most at risk of infection. If you develop symptoms of cough, fever or shortness of breath, talk to your doctor and follow their instructions on self-quarantine or seeking further medical attention. It is also very important that you always wash your hands and maintain social distancing whenever possible.With so much news coverage devoted to COVID-19, what is the effect on someone's mental health?
Everyone reacts differently to stressful situations, with fear and worry about yourself and those around you. People can have changes to their eating patterns, difficulty sleeping and feelings of fear, anxiety and depression. It is a stressful time, don’t forget to support yourself in a healthy manner. Take breaks from following stories about the pandemic, take care of your body with exercise, stretches or meditation. Try to eat healthy, well balanced meals and talk to others who you trust about how you are feeling.
Here are a couple of key numbers that should be available to anyone that needs help.
- Contact the Disaster Distress Helpline: 1-800-985-5990
- Contact the National Domestic Violence Hotline: 1-800-799-7233 and TTY 1-800-787-3224
If a person passes away from COVID-19, can their body still carry the disease and potentially infect other people?
According to the CDC, It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose or possibly their eyes, but this is not thought to be the main way the virus spreads.
People should consider not touching the body of someone who has recently died of COVID-19. Older people and people of all ages with severe underlying health conditions are at higher risk of developing serious COVID-19 illness.
There may be less of a chance of the virus spreading from certain types of touching, such as holding the hand or hugging after the body has been prepared for viewing. Other activities, such as kissing, washing and shrouding should be avoided before, during and after the body has been prepared, if possible. If washing the body or shrouding are important religious or cultural practices, families are encouraged to work with their community cultural and religious leaders and funeral home staff on how to reduce their exposure as much as possible.
Should we practice social distancing with our spouse or significant other?
If you have any symptoms, you should certainly try to stay away from others in the home, even so far as to have a designated “sick room” away from others in the home with use of a separate bathroom, if available. If you are both asymptomatic and you have had no exposure to someone else who is sick, you should do all of the things we mention to reduce the risk of spread of potential infection: try avoid sharing utensils, wash your hands, clean surfaces regularly and cough into your elbow.
As a person who cleans homes for a living, is it safe for me to still clean them? No one else is inside the home when I'm there.
Talk with your employer to see if you should receive specific training on limiting the spread of illness and providing increased attention to high touch surfaces in the home. To protect yourself, consider calling ahead to see if your customers are having any symptoms such as fevers, cough or shortness of breath which could put you at risk. The virus can be present on surfaces for several days. Protect yourself with frequent hand washing, use gloves and avoid touching your face if at all possible.
How do you shop for and clean fresh produce during the coronavirus outbreak? Do we really have to wipe down boxes, packages and food from the grocery store with a bleach solution?
There is currently no evidence to suggest that COVID-19 can be transmitted through food or water systems, but sharing food and beverages is discouraged to reduce the risk of sharing saliva. Proper home food safety is advised, including promptly refrigerating foods, keeping raw and cooked foods separate, rinsing fresh produce and heating food to the appropriate internal temperature. While it is OK to wipe down some packages you get from the store, the most important step to remember is to always wash your hands after handling packages and avoid touching your face.
Is it safer to breathe through your nose instead of through your mouth when in public places?
The virus is spread through respiratory droplets from infected people. If you are in close contact (fewer than 6 feet) from a sick person who is coughing or sneezing, these droplets can be inhaled through your nose or mouth. Breathing through your nose or mouth will not make a difference. You should avoid public places and distance yourself from others.
Are people living with HIV or AIDS who are already on antiviral drugs less at risk for contracting COVID-19?
HIV treatment (or antiretroviral therapy) involves antivirals targeted against human immunodeficiency virus. There is no evidence that people living with HIV on antiretroviral therapy will have a lower likelihood of acquiring COVID-19 and the use of these medications should not be encouraged as treatment or prophylaxis for COVID-19. There was some thought that one particular HIV drug (Kaletra) might be effective against COVID-19 but the early research indicates it probably does not have any benefit in preventing or treating COVID-19.
Does COVID-19 thrive in cold temperatures? Should I keep my house warmer than usual?
The most effective way to protect yourself from COVID-19 is with frequent handwashing with soap and water or using hand sanitizer and social distancing. We really don’t know whether or not there will be a seasonal component to this. At this time, we assume that COVID-19 can be transmitted anywhere, regardless of how hot or humid the air is.
Is hand sanitizer still effective if it’s expired?
Sanitizer past its expiration date may still have some effectiveness, because it still contains alcohol which is the active ingredient. Try to use hand sanitizer that contains at least 60% alcohol.
I live alone, go out to the deck in my building to walk once a day and wash my hands like I should. Do I need to sanitize apartment daily (e.g, wipe down things)?
You should try to sanitize "high-touch" surfaces or places which you frequently touch. Frequent hand hygiene and distancing yourself from others are also important strategies that you should continue practicing regularly.
People all over Facebook are asking craft people to make and donate masks for hospitals. Is a homemade mask protective for medical professionals?
Given the recent shortage of personal protective equipment for healthcare professionals, the CDC has indicated that homemade masks (banda, scarfs) can be considered for use by healthcare practitioners as a last resort when proper facemasks are not available. Homemade masks are not considered protective equipment since their capacity to protect is unknown. Caution should be exercised when considering this option. They should be used in combination with a face shield that covers the entire front and sides of the face.
I recently moved into a new apartment and this weekend wanted to have a few family members over for dinner, maybe 6 to 8 of us. Is this okay? And also, what if your family you're staying with is big, say 10 or more? What are the recommendations for large families?
It is recommended to continue with social distancing strategies and frequent hand hygiene to avoid any possible community spread. You should consider postponing any non-essential meetings including large family gatherings. Another option would be to have virtual meetings. When smaller gatherings must occur, make sure nobody is sick with fever, cough or shortness of breath and that nobody has had recent contact with a COVID-19 patient.
Since this is a respiratory virus, will we see an exponential increase with those who are vaping?
People with underlying pulmonary disease are at risk of developing severe illness from COVID-19. Smoking or vaping might compromise the ability of the upper airways to clear bacteria and viruses in general. However, there are no studies available regarding COVID-19 in this group.
I was wondering if it's safe to use my own reusable bags when I go grocery shopping? Or should I use the plastic ones provided by the store? If I do use my own, should I disinfect them when I bring them home?
It is safe to use reusable bags and clean them as you normally would. Also remember to practice frequent hand hygiene.
Is it safe to consume fresh produce that is not wrapped and has been handled by customers?
There is no reason to fear consuming fresh produce.
Is there new guidance about not taking ibuprofen to treat COVID-19?
There is no scientific data on the harms of ibuprofen in treating COVID-19. Until there is more firm evidence, the World Health Organization recommends avoiding ibuprofen and considering acetaminophen instead. Again, there is no firm data to show harm, but until there is, it is recommended that ibuprofen be avoided. Acetaminophen should be taken as per medication instructions, and you should ask your doctor if you have any specific concerns about taking this drug that are related to other medical issues.
I keep reading that if you have Type A blood then you are more likely to be susceptible to getting the coronavirus. Is this true?
According to one study published from Wuhan, China, people with certain blood types were more likely to have the infection. The increased chance for infection was small. Since it is only one study, more studies are needed to confirm this.
What is the difference between community exposure and community spread of the virus?
Community exposure is being exposed to the risk by people who live around you in the community, rather than by someone who traveled from an area with infections. Community spread is when the virus is spreading among people in the general community in which you live.
I have seen posted on Facebook that gargling with a mixture of warm salt water or water/vinegar kills the coronavirus germs in the first four days when you start with the sore throat and am wondering if this is fact or fiction?
Gargling salt water may improve sore throat symptoms, but it does not kill viruses and germs. If you are sick, you should stay home and limit your contact to others to avoid infecting them.
If someone dies and they are infected with COVID-19, can other people catch the virus from the body if there was an open casket viewing at the funeral?
Per the CDC, there is currently no known risk associated with being in the same room at a funeral or visitation service with the body of someone who died of COVID-19. The CDC does currently recommend that people should not touch the body of someone who died of the novel coronavirus.
What treatment they are giving quarantined patients with this virus that are recovering (not on ventilators) so people at home under self-quarantine can do the same? Is it Tylenol, Advil, Vicks, Robitussin or just plain old chicken noodle soup and rest?
There is currently no specific treatment for COVID-19. Several experimental drugs are undergoing clinical trials, which we can hopefully use in the near future. If a patient is infected with the virus and under quarantine, they can take medications to manage their symptoms, including acetaminophen, ibuprofen and any cough suppressant. There is currently no evidence to support that ibuprofen is worse than acetaminophen for patients with COVID-19. It is encouraged to drink fluids and rest as well. It is also important to take measures to avoid spreading the virus while a patient is under quarantine. The CDC website has good tips for doing this.
Flattening the curve is necessary to save lives, but will it extend the outbreak?
"Flattening the curve" refers to delaying development of an outbreak by lowering infection rates. This is important so hospitals do not have a large surge of sick patients all at once and can better care for patients. This is done by implementing community mitigation strategies, like closing schools, which will reduce the number of overall cases and blunting the outbreak peak. The slow increase in cases over a longer period of time gives the healthcare system time to adapt.
I’m seeing posts that say the virus lives in the throat for 4 days and that gargling with salt water kills it.
This is false. The incubation period (the time it takes for symptoms to develop) is thought to be between two and 14 days, but most commonly symptoms seem to emerge around five days.
It is incorrect to suggest that people could cure themselves by gargling during this time. Although the virus is transmitted via respiratory secretions, there is no evidence that the virus remains in the throat and that gargling water (whether in plain form or as saline/vinegar) will help eliminate the virus. There also is no evidence that regularly rinsing the nose with saline can prevent respiratory infections, including COVID-19.
There is a lot of misinformation concerning COVID-19, mostly coming from social media. Make sure you can fact check any information with verified sources such as CDC or WHO.
Is the coronavirus able to get into our water supply?
The COVID-19 virus has not been detected in drinking water. Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus.
Because our skin serves as a protective organ, people with compromised skin due to conditions such as severe eczema or psoriasis can be at greater risk for infection. Does a compromised skin condition put one at any increased risk for contracting the coronavirus?
The virus enters the body through the nose, eyes and inhaling through the mouth mainly through respiratory secretions from person-to-person. It does not infect the skin. Droplets from respiratory secretions can land on surfaces and remain viable for hours to days depending on different factors. The most important strategy to prevent getting sick is frequent hand washing as this will remove the virus from your skin and avoid it from reaching your eyes, nose, mouth.
There is no evidence of increased risk due to compromised skin condition as long as you practice frequent hand washing.
Is the damage to the lungs because of the virus reversible after recovery or is it permanent?
Most of the people that have been infected around the world have recovered. Some of them have had reduced lung function and experienced difficulty breathing with exercise. However, these patients can perform rehabilitation exercises to improve their lung capacity over time. It is still too early to establish long-term effects of the illness.
We've have heard so much info about what you should be doing about certain preventions, but my question is what should we be doing specifically in our everyday lives?
Reasonable precautions that would be recommended in your everyday lives should include regular hand washing with soap and water and avoiding events with large crowds, especially events with large crowds indoors. If you have developed respiratory symptoms and are invited to a family gathering, it would be advisable to stay home. Although there hasn't been community transmission of the novel coronavirus proven within Missouri, all viruses that cause respiratory symptoms are spread through respiratory droplets in the same way as the novel coronavirus. If you are not sick, avoid contact with sick people. When out at a restaurant or shopping, avoid touching your eyes, nose, or mouth with unwashed hands and clean your hands often by washing them with soap and water for at least 20 seconds or using alcohol-based sanitizer that contains 60% alcohol.
If you have to use a public laundromat what precautions should you take, or should they be avoided completely?
There are no specific precautions other than the above that need to be taken for laundromats and they do not need to be avoided. When washing clothes, the CDC recommends:
"Read and follow directions on labels of laundry or clothing items and detergent. In general, using a normal laundry detergent according to washing machine instructions and dry thoroughly using the warmest temperatures recommended on the clothing label."
Respiratory viruses such as coronavirus are spread through direct person-to-person contact. They are less commonly spread through indirect contact via contaminated surfaces. And when spread occurs indirectly, the risk is mainly with hard surfaces. The bottom line remains that good hand hygiene and avoidance of sick contacts are the key interventions, especially when out in public areas.
On average, how many weeks did it take for other countries to start seeing a decline in the number of cases?
The first cases of coronavirus were reported in China at the end of December, 2019. The WHO declared the outbreak a Public Health Emergency of International Concern on January 30th, at which time the number of cases had increased to over 9000. With extremely aggressive public health measures including massive quarantine efforts, the construction of new hospitals, and widespread testing at no cost to the public, the number of new cases per day had decreased dramatically by mid-February. In contrast, Coronavirus was first detected in Italy in January, and until the third week of February there were only 3 reported cases. Today, Italy is reporting over 10,000 cases without any clear signs of slowing yet. The trajectory of the outbreak in the US is difficult to predict right now.
What criteria enabled the WHO to label this illness a pandemic?
There was no specific threshold that was crossed that prompted the WHO to label this as a pandemic and there are no set cutoffs that differentiate an "epidemic" from a "pandemic." The decision was made based on a number of factors, most importantly the anticipated trend. Pandemic refers to the global outbreak of a new disease that is actively being transmitted in multiple different regions. Although this was as true of coronavirus last week as it is this week, the decision to officially label this event as a pandemic was based on global trends that show a sudden increase in the number of cases outside of China.
What are the recommendations for road trips, would this be discouraged along with all other non-essential travel?
By avoiding airports and large crowds road trips would be expected to be lower risk than air travel. Non-essential travel to regions of the U.S. where there is known to be community spread of disease, including the Pacific Northwest, Northern California, Los Angeles and New York is definitely discouraged no matter the mode of transport.
With spring break here, what is the responsible thing for vacation goers to do at this point?
Those people who are at a higher risk (including elderly or with other medical conditions) should certainly reconsider non-essential travel. There is increased risk of exposure at airports, on public transportation and in places where large people can gather. Confirmed community spread (that is, non-travel related) is, right now, limited to a few states. However, that is rapidly changing and local spread will continue to increase in the coming days to weeks. In general, people should consider canceling and rescheduling any non-essential travel, especially if those plans include going to crowded or popular destinations or areas with a lot of community transmission.
If you think you might have coronavirus, whom do you call?
If you are concerned about you or a family member having COVID-19, you should contact your family doctor and explain your symptoms. He or she may direct you to make an appointment or see another doctor for testing. This testing may be at a local clinic or at the local emergency department. If you feel sick, your goal should be to stay home and avoid getting others sick unless absolutely necessary. You should follow your doctor's instructions, contact your employer and do your best to avoid crowded areas while you are sick.
Any info on washing our bedding. Just hot water? Extra-long wash cycle? Extra rinse? Vinegar, bleach?
The CDC has instructions for management of patients who have concern for, or confirmed, COVID-19:
Immediately remove and wash clothes or bedding that have blood, stool, or body fluids on them. Wear disposable gloves while handling dirty clothes and bedding and keep soiled items away from your body. Clean your hands (with soap and water or an alcohol-based hand sanitizer) immediately after removing your gloves. Read and follow directions on labels of laundry or clothing items and detergent. In general, use a normal laundry detergent according to washing machine instructions and dry thoroughly using the warmest temperatures recommended on the clothing label.
We are hearing a lot about “social distancing,” what exactly does that mean and how does it help prevent the spread of disease?
Social distancing means remaining out of crowded places, avoiding large gatherings and maintaining distance (approximately 6 feet or 2 meters) from others when possible. As community transmission ramps up in a particular area, social distances measures will be increased as well.
Are any special precautions required for food preparation to minimize the risk of coronavirus transmission?
There is no evidence that COVID-19 can be transmitted to people through contact with food. These viruses should be killed by normal cooking temperatures. The most important preventative measure continues to be good hand hygiene with frequent hand washing. As always, people should follow normal food preparation practices including avoiding raw or under-cooked meats and unpasteurized dairy products. You should not share food, utensils or cups with a person known or suspected of having CVOID-19.
Is denatured alcohol, like what you get in a hardware store, an adequate disinfectant for surfaces?
Denatured alcohol is commonly used as an industrial surface disinfectant and has anti-viral properties against some viruses including coronavirus. However, additional chemicals are added to these cleaners that can be toxic if absorbed through the skin. We would not recommend denatured alcohol for routine disinfectant use in the household. People should use household cleaners and EPA-registered disinfectants that are appropriate for the surface, following label instructions.
Denatured alcohol should definitely not be used for hand washing. Alcohol solutions that are labeled as hand sanitizers are helpful if available but have not been shown to be any more effective than soap and water. To be effective, any hand sanitizer should contain at least 60 percent alcohol.
How long does it take for the state to get results from a COVID-19 test? And then how long does it take the CDC to confirm the result of that test?
The time it takes for the health department to test the sample and have results available is influenced by several factors. The result for a test for COVID-19 can be available in as little as six hours to up to two days. The commercial laboratories which currently offer COVID-19 testing take three to four days for results. This time frame is a combination of the time it takes to transport, process and analyze the sample, as well as how many samples are being tested at once. Once results are available, the ordering physician is notified promptly of any positive test.
Would it be possible to take antibodies from someone who had it and recovered and put them in someone currently infected? Would this help an infected person recover quicker?
There is no data on the treatment of COVID-19 with manufactured or natural antibodies. There were several studies on the use of antibodies in the treatment of SARS-coronavirus in 2006 but these were inconclusive and possibly caused additional harm. There are scientists and physicians working to try to create antibodies to treat COVID-19 now, but it is too early to tell if these will be effective.
Does the pneumonia shot help prevent COVID-19 complications?
The pneumonia shots, or Pneumovax and Prevnar vaccinations, are vaccines that help protect patients against a particular bacteria called Streptococcus pneumoniae (Pneumococcus), which commonly causes bacterial pneumonia in older patients or those with underlying lung or immune conditions. It does not provide any protection against viral infections.
If a pregnant woman has an appointment with her doctor at a hospital, should she be worried about an increased chance of being exposed to COVID-19?
Hospitals and clinics are being proactive to screen patients for respiratory symptoms before they enter the facility to prevent any exposures. Pregnant women should practice the usual infection prevention techniques of hand washing and avoid those who are sick.
If the coronavirus is a respiratory illness, why are so many people buying toilet paper?
There is concern that because toilet paper is manufactured in Japan there will be shortages. However, there is no evidence to suggest that supply will be interrupted. There is also fear that people will get quarantined in their homes, therefore, they feel the need to stockpile many different items including toilet paper. However, there is no current plan to quarantine people for prolonged periods of time.
If you are placed in isolation for two weeks with coronavirus, who clears you to go out in public again?
The physician taking care of you as well as the state health department will let you know when it is okay for you to go out in public again.
Are newborns at higher risk? My daughter is about to have a baby and we're terrified that we should not allow visitors after the birth.
At this time, there is no evidence to suggest that children are at higher risk. The usual infection prevention techniques should be used including frequently washing hands and avoiding people who are sick.
Is it true that black people can't get it because of the melanin in their skin?
There is no evidence to support this claim. COVID-19 spreads person-to-person through respiratory droplets that land in mouths or noses or are inhaled into the lungs. Anyone who comes into close contact with someone infected is at risk of getting the infection.
How do people with compromised immune systems best protect themselves from COVID-19?
For people with compromised immune systems the best way to protect yourself is to avoid people who are sick, avoid touching your eyes, nose and mouth, clean and disinfect frequently touched objects and surfaces using regular household cleaning products, wash your hands often with alcohol-based hand sanitizer or soap and water for at least 20 seconds.
What is the length of time from exposure to onset of symptoms and when can someone first test positive for the virus?
Symptoms may appear between two and 14 days after exposure. We are still learning about the virus. Some studies of small groups of hospitalized people infected with the virus show that many have viral genes detected in their noses for at least seven days, and a few longer. We do not know if that means they are still infectious. The onset and duration of viral shedding and period of infectiousness for COVID-19 are not entirely known.
The virus is spread by droplets of spittle from infected people and passed around by coughing and sneezing. But some infected people are asymptomatic. Can people without symptoms spread the illness?
People are thought to be most contagious when they are symptomatic. Asymptomatic infection has been reported and there might be some spread before people develop symptoms, but this is not thought to be the main way the virus spreads.
Can the coronavirus be spread by money?
It is not certain how long the virus survives on surfaces or money. In general, coronaviruses do not survive well on surfaces and a recent study found that, of the surfaces studied, paper was the least likely surface to harbor virus.
What information do we know about the people who have died because of COVID-19? What percentage of them had underlying medical conditions?
The data on mortality for COVID-19 is still a moving target and varies by age group and underlying health conditions. It appears that people with underlying lung disease, heart disease or other conditions that impair the immune system are more at risk. We do not have complete details about the medical conditions of every person who has died from COVID-19, but patients aged 65 years or older were more likely to have severe infections.
Is the coronavirus able to spread via recirculated air, like in office buildings, hospitals, public transit vehicles and our homes?
According to researchers at Purdue University, COVID-19 could circulate inside cruise ship air conditioning systems. They say on aircraft, the coronavirus is more likely to spread by touch than through the air. And the World Health Organization says there is “very little risk” of any communicable disease being transmitted on board an aircraft.
Do I need a face mask?
Many people are wondering if they need a face mask — and are worried about price gouging.
Yes, some of these masks are going for hundreds of dollars on Amazon, and local stores are in short supply. But luckily, you really don't need a mask unless you are the one with the virus, or if you're working in the medical field.
Masks stop germs from spreading. They're not necessarily helpful in protecting yourself from the virus.
The general public is being told not to wear face masks as they won’t help keep us from getting sick, but health professionals are supposed to wear them. Why do the masks protect them but not us?
Health professionals need to wear face masks because they are in very close contact with sick patients throughout the day as part of their job. It is also recommended that those who are taking care of someone who may have COVID-19 wear a face mask when in close contact.
It is not recommended that people who are well wear a face mask as it is not the most effective way to protect yourself.
The most effective way to protect yourself and others includes frequent hand washing with alcohol-based hand rub or soap and water, covering your cough with the bend of your elbow or tissue and maintaining distance from those who are coughing or sneezing.
Are infected people recovering?
People also want to know what happens to people after they're infected with the virus. There's some good news here, according to Dr. Sean Whelan from Washington University's Department of Molecular Biology.
"People are OK after they get the virus, 98% who get tested recover and then presumably are immune for the rest of their life," Whelan said.
Is it safe to travel?
We've also received several questions about travel. You might need to change your plans, depending on where you're headed.
Guidelines from the CDC are changing frequently. Click here for the latest information about travel within the U.S. and click here for the latest information about international travel and the outbreak.
I am supposed to go to Seattle this week, is it foolish to go?
The CDC provides notices based on the risk in travelling to specific areas. It is recommended to avoid nonessential travel to destinations with warning level 3 travel notices because of the risk of acquiring COVID-19.
People in high-risk groups, including older adults and those with chronic medical conditions, traveling to alert level 2 destinations should talk to a healthcare provider and consider postponing their trip because COVID-19 can be more serious in these groups.
CDC does not recommend canceling/postponing travel to destinations with watch level 1 travel notices because the risk is low. A list of destinations with travel notices is available on the CDC website here.
You can consider cancelling trips if the anxiety of going would make you not enjoy your trip. If you travel, take the following precautions:
- Avoid contact with sick people
- Avoid touching your eyes, nose or mouth with unwashed hands
- Clean your hands often by washing them with soap and water for at least 20 seconds or using alcohol-based sanitizer that contains 60% alcohol
Could my online orders carry coronavirus?
People are worried about online orders from China, from sites like Amazon or Wish. But according to the Centers for Disease Control, there's little chance the virus would spread like this.
There's no evidence that coronavirus in the US is associated with imported goods. So right now, don't worry about your online shopping habits.
Are there coronavirus tests available in St. Louis? If yes, will your regular physician have access to them in their office or does a patient have to go somewhere else for testing?
The CDC has shipped the laboratory test kit for the COVID-19 (SARS-CoV-2) to approved laboratories, which includes Missouri's state public health department laboratory. Currently, this test is not available at local clinics but can be sent by a healthcare provider to the health department during a routine visit.
A healthcare provider will determine if a patient has signs, symptoms and the appropriate exposures compatible with COVID-19 and will then provide materials for testing. The decision on which patients receive testing should be based on the local epidemiology of COVID-19 as well as the clinical course of illness.
Commercial labs are working to develop their own tests that will hopefully be available soon.
