Our understanding of “long COVID”

For this preliminary entry to the long COVID discourse, researchers in the JAMA study isolated 875 subjects from the health monitor-wearing database (all of whom wear Fitbits), and compared those who had tested positive with COVID to those who had reported “a fever, cough, body aches or other symptoms of a respiratory illness” due to another infection.

It took an average of 79 days for their resting heart rates to return to normal, compared to just four days for those who didn’t have COVID… More here.
