The World Health Organization has published its definition of the syndrome known as long COVID or as the U.N. health agency refers to as 'post COVID-19 condition,' a name proposed by WHO's International Classification of Diseases.

"Post COVID-19 condition occurs in individuals with a history of probable or confirmed SARS-CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms that last for at least 2 months and cannot be explained by an alternative diagnosis," the WHO stated in a brief. 

The brief also outlined, "Common symptoms include fatigue, shortness of breath, cognitive dysfunction but also others...which generally have an impact on everyday functioning. Symptoms may be new-onset, following initial recovery from an acute COVID-19 episode, or persist from the initial illness. Symptoms may also fluctuate or relapse over time."

While there are several risk factors that make covid infection more dangerous including obesity, diabetes, high blood pressure and smoking, a clear link has not been established between these factors and long COVID.

More studies are being done and treatment protocols and being created to treat this syndrome.
