ST. LOUIS (KSDK) - There's an increase in flu cases in Missouri, according to the Center for Disease Control and Prevention.

Doctors in local hospitals say they are seeing the uptick firsthand -- especially among young adults. They say the increase was particularly prominent this month.

Symptoms to look out for include high fever, body aches, headache and a dry cough. The virus is spread through oral droplets, meaning coughing and hand contact with someone who just sneezed.

Doctors say the flu usually lasts three to four days, and if you get it, all you really can do it ride it out.

"People should be concerned about family members that have significant what we call comorbiditie -- other illnesses such as severe lung disease, heart disease, diabetes that have a weakened immune system, or if they are elderly those family members need to be watched carefully if they show signs of confusion, inability to eat and drink, they probably should seen emergently," said Dr. John Fortney, with Mercy Hospital St. Louis.

Doctors say if you haven't been vaccinated yet it's not too late to get your flu shot.
