Published in the British Medical Journal on Wednesday, the peer-reviewed research looked at nearly two million medical records, and matched up around 300,000 people who had lab-confirmed infections with another 300,000 who didn't test positive for SARS-CoV-2.
The researchers found that various types of health issues after a mild case of COVID lingered for several months, but cleared up within the first year after an infection.
Certain symptoms, including weakness and difficulty breathing, were more likely to persist.
"There are patients who are experiencing long COVID symptoms for a year, and their life changes, and they suffer — we do know that," said Dr. Maytal Bivas-Benita, a senior researcher at KI Research Institute in Kfar Malal, Israel. "But when we look at this large population and we look at their medical records, what we see is a small number of symptoms that last, and we see that they decrease with time."
