What steps should my school take if a student or staff member starts to show symptoms of COVID-19?
It is best to seperate that person from the school by sending them home. Also, according to the CDC you should keep track of their symptoms and if they are having trouble breathing they should see a medical professional immediately. This is the time to activate your preparedness plan. https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/steps-when-sick.html
