The World Health Organization (W.H.O.) states Long COVID "can affect anyone exposed to SARS-CoV-2, regardless of age or severity of original symptoms." The definition of Long COVID is the "continuation or development of new symptoms 3 months after the initial SARS-CoV-2 infection, with these symptoms lasting for at least 2 months with no other explanation." Common symptoms of Long COVID can include fatigue, shortness of breath, and cognitive dysfunction, but more than 200 different symptoms have been reported that can have an impact on everyday functioning. "Studies show that around 10–20% of people infected by SARS-CoV-2 may go on to develop symptoms that can be diagnosed as Long COVID. Although exact numbers of those living with the condition are uncertain, it is believed that more than 17 million people across the WHO European Region may have experienced it during the first two years of the pandemic (2020/21)." There are estimates of 23 million+ COVID Long Haulers alone in the United States (and probably more due to it being likely an underestimate). It's very difficult to get accurate statistics due to a lack of good diagnostics for Long COVID and failure to identify initial COVID infection in many people. It is a tremendous, wide reaching problem, that's only increasing with every variant. Good SARS-CoV-2 antivirals need to be developed to combat this fast growing issue. In the mean time taking every precaution reasonably possible is best.
