October 5. A majority of individuals recover from a SARS-CoV-2 infection within a few weeks after the onset of symptoms. However, a substantial number of individuals continue to experience COVID-19 symptoms more than 3–4 weeks after contracting the virus.
Health experts refer to the symptoms that persist beyond this acute phase of a SARS-CoV-2 infection as long COVIDTrusted Source.
The presence of persistent symptoms following an acute infection, known as the post-viral syndrome, is a common feature of other viral infections. To evaluate the specificity of long COVID symptoms, the researchers compared the incidence rate of long COVID symptoms after COVID-19 with those observed after flu.
The study, which appears in the journal PLOS Medicine, found that more than one-third of the COVID-19 patients had long COVID symptoms 3–6 months after a SARS-CoV-2 infection. Moreover, long COVID symptoms were more common in women, older adults, and individuals with severe symptoms during the acute phase.
