If you test positive but don’t have symptoms, you need to
1) isolate for five days instead of 10 — and 2) continue to wear a mask around others for five more days.
People who were sick but whose symptoms are improving and don’t have a fever can also leave the house after five days, as can those who were exposed to Covid-19 but are fully vaccinated.
The CDC says the change is based on scientific evidence that most transmission occurs early in the disease, right before and after the onset of symptoms.
