What causes symptoms in COVID long haulers?
More studies will shed light on why these stubborn health problems persist in some people. In fact, long COVID can happen in people who have mild symptoms, although patients with more severe initial illness seem to be more likely to have long-term impairments. While it’s clear that people with certain risk factors (including high blood pressure, smoking, diabetes, obesity and other conditions) are more likely to have a serious bout of COVID-19, there isn’t a clear link between these risk factors and long-term problems.

Parker, M.D., Ph.D., who specializes in lung disease and critical care, discuss long-term COVID-19, what symptoms are most common and what those affected by them can expect.

But in some others, long-term effects of COVID-19 can cause lingering health problems and wreak havoc for months.
