It has become increasingly clear that infected patients have symptoms not only in the acute phase, but also after recovery from the initial infection.
A recent meta-analysis including 4828 patients with post-COVID-19 showed that symptoms and post-acute sequelae of SARS-CoV-2 can persist weeks to months after the infection.
These patients who reported persistent symptoms have been termed "long haulers" or described as having long COVID, post-acute COVID-19, persistent COVID-19 symptoms, post COVID-19 manifestations, long-term COVID-19 effects, post-acute sequelae of COVID-19 (PASC), or post-COVID-19 syndrome.
