Most people get ME/CFS after an infection. We estimate that 100,000 people or more might get it after Covid-19, which makes this an important group to understand.

DecodeME will look to see if people who get ME/CFS after having Covid have genetic differences from others. If they do, that will indicate they have different causes, needing different treatments.
