As of early July 6, there have been nearly 2.9 million confirmed cases of COVID-19 in the United States, according to Johns Hopkins University's oft-used tracker. Of those, 906,763—about 31%—are listed as "recovered." But recovery isn't the same for everyone. The World Health Organization reports the median time for recovery is up to two weeks for those with mild cases, while those with more severe cases can take up to six weeks for symptoms to resolve.

Some people, however, say they continue to experience symptoms months after infection. In doctor visits and on social media groups, a growing number of patients report lingering symptoms ranging from mild issues, such as continued loss of taste or smell, to more serious ones, such as heart palpitations, chest pain, shortness of breath, extreme fatigue, cognitive difficulties or recurring fevers. Whether these symptoms eventually resolve or whether they signal permanent damage from the virus remains unknown.

"It has been just six months since the virus was detected in China, so nobody can tell you for sure if these are short-term or long-term complications," said Dr. Samer Kottiech, a cardiologist in New York City who estimates 90% of his patients who come in after COVID-19 infections experience prolonged symptoms.
