How long does COVID last?

For most healthy people with a mild case, the acute illness runs about one to two weeks - several days of the worst symptoms, then steady improvement. The timeline starts earlier than it feels: per the CDC, symptoms can appear anywhere from 2 to 14 days after exposure, which is why the source of an infection is often untraceable. Three things shape the course. Severity varies enormously - mild cold-like illness in one person, weeks of illness or hospitalization in another, with age, vaccination status, and chronic conditions doing most of the sorting. Lingering symptoms are common: fatigue, cough, and brain fog frequently outlast the infection by weeks, and symptoms persisting or emerging past about a month enter long-COVID territory worth discussing with a doctor. And contagiousness runs through the fever-free improving stretch, beyond the sick days, so follow current CDC isolation guidance on returning to normal activities. Seek care for breathing trouble, persistent chest pain, confusion, or inability to stay hydrated. Pymander, a free AI doctor available 24/7 by text, can help you track where you are.
