To ensure affected patients get better care, the WHO has come up with a ‘clinical case definition’ of ‘post-Covid condition’, stating that it occurs in individuals with a history of probable or confirmed Sars-CoV-2 infection, usually three months from its onset with symptoms, lasts for at least two months, and cannot be explained by an alternative diagnosis.

“Symptoms include fatigue, shortness of breath, cognitive dysfunction but also others and generally have an impact on everyday functioning,” the definition states. “Symptoms may be new onset following initial recovery from an acute Covid or persist from the initial illness. Symptoms may also fluctuate or relapse over time,” it adds. WHO makes it clear that a separate definition may be applicable for kids. This definition is being cited by the WHO as a first necessary step to optimise the recognition and care of people experiencing ‘post Covid-19 condition’.
