ATLANTA, GA-If you get sick with COVID-19 and are at higher risk for severe illness, antiviral treatments are available that can reduce your risk of hospitalization and death. But it’s important to get on treatment within 5-7 days after you first develop symptoms.
Rebound, a return of symptoms or a new positive test after having tested negative, has been reported in people with and without the use of COVID-19 antivirals. Current evidence suggests rebound presents as mild symptoms 3-7 days after initial illness resolves. If you are at high risk for severe COVID-19, treatment benefits outweigh the potential risks of rebound.
