After a recovery, how long do COVID-19 symptoms last? Although we are now about ten months into this pandemic, we simply don’t have enough information to answer that question definitively. However, there are indications that many people suffer for weeks and some unlucky ones may struggle with symptoms for months.
Evidence on How Long COVID-19 Symptoms Last:
A study of 965 individuals in South Korea suggests that 9 out of 10 people who recover from COVID-19 report symptoms weeks later. (The Korea Disease Control and Prevention Agency is preparing the results of this online survey for publication.) More than a fourth of the respondents said they are troubled with fatigue. Almost as many are having difficulties concentrating. While disappearance of the senses of both taste and smell suggest a possible COVID-19 diagnosis, these symptoms may also linger after a person is no longer infected.
COVID-19 Symptoms Last Weeks in the US:
The US CDC has also noted that people may experience fever, chills, muscle pain, and heart inflammation, known as cardiomyopathy, up to three weeks following recovery. The agency conducted a telephone survey of 292 individuals who had tested positive for SARS-CoV-2 two to three weeks earlier. Among respondents, 35 percent said they were not yet back to their previous state of health. In addition, 94 percent described at least one symptom that was still troubling them. (This proportion is quite similar to that identified by the KDCPA.) They named cough, shortness of breath and fatigue as continuing symptoms. Many also reported recurrent or long-lasting headache symptoms.
According to the CDC, COVID-19 can cause lasting health problems even among younger people and those who had mild cases. Although 47 percent of older people (over 50) report that their COVID-19 symptoms last for weeks or even months, 26 percent of young people between 18 and 34 years old were still suffering two to three weeks later. In comparison, 32 percent of those between 35 and 49 had long-lasting health problems.
Different from the Flu:
By way of comparison, more than 90 percent of people diagnosed with influenza last year had returned to their baseline health status within two weeks. To state the obvious, COVID-19 is not the flu.
