For some people, COVID-19 symptoms can last anywhere from four weeks to six months after testing positive for the virus. These patients, given the name "long haulers", have in theory recovered from the worst impacts of COVID-19 and have tested negative. However, they still have symptoms of what's being called "long COVID." There seems to be no consistent reason for this to happen.
This condition can affect anyone – old and young, otherwise healthy people and those battling other conditions. It has been seen in those who were hospitalized with COVID-19 and patients with very mild symptoms. Studies indicate that about 10% of people infected with COVID-19 will experience long-haul symptoms.
