COVID-19 was full of surprises early on, causing mild problems in the short term for some people and serious complications for others, according to the American Heart Association.
Long term, it may be just as capricious.
Studies are spotting potential heart and brain problems up to a year after infection with SARS-CoV-2, even in people who had mild COVID-19.
The possible long-term effects include “a myriad of symptoms affecting different organs,” said Dr. José Biller, director of the COVID-19 neurology clinic at Loyola Medicine in Maywood, Illinois. “So, it could be the lungs, it could be cardiovascular, it could be the nervous system, it could be mental health or behavioral problems.”
Estimates vary widely on how many people may be affected. Research suggests about 10% to 20% of people experience mid- or long-term issues from COVID-19, according to the World Health Organization.
