Prevalence of Long Covid

Apparent prevalence likely varies due to differences in population age and health; method of data collection; which symptoms were considered; time since Covid-19 infection; vaccination status; differences in cultures and beliefs etc

The Risk of Getting Long Covid Increases With Each Infection

"The chart shows you the cummulative probability of getting Long Covid at different estimates of risk for each additional new infection. It assumes that the risk does not increase or decrease with each infection but remains the same (some studies have shown it may increase). Different studies have calculated different risks based on different and definitions. One as low as 1%, some as high as 50%. The CDC [America's Centre for Disease Control and Prevention] is 20%."
