ST. LOUIS (KSDK) – For the second time in one week local students have been diagnosed with scabies.

Last week we told you about three cases in De Soto schools, and now students in Saint Louis Public Schools have been diagnosed.

This is actually the second time in the past few weeks they've had scabies at the Academy of Environmental Science and Math Elementary School near Midtown. This time, any kid suspected of having them can't come back until a doctor says they can.

The school district is working with the city health department, and they are screening all 800 children who go to school there and all adults at the school. To do this, they've brought in extra nurses and so far they've screened about half of the students. Of those 400, the school says fewer than 20 have shown signs of scabies.

The nurses won't actually diagnose scabies. That's where the doctor comes in. If the nurses determine a student shows signs of scabies, the school says they can't come back until they are cleared by a doctor.

Dr. Nirav Patel, an infectious disease specialist at Saint Louis University, joined NewsChannel 5 at 5 p.m. to talk about where scabies come from, and how they are transmitted.
