People with COVID-19 have had mild to severe respiratory illness with symptoms of:
- Fever of 100.4 degrees or higher
- Shortness of breath
COVID-19 spreads through respiratory droplets produced when an infected person coughs or sneezes. That is why CDC recommends that these patients be isolated either in the hospital or at home (depending on how sick they are) until they are better and no longer pose a risk of infecting others. How long someone is actively sick can vary so the decision on when to release someone from isolation is made on a case-by-case basis in consultation with doctors, infection prevention and control experts, and public health officials and involves considering specifics of each situation including disease severity, illness signs and symptoms, and results of laboratory testing for that patient.
Symptoms may appear 2 to 14 days after exposure.
