My wife likely had covid in March (she was unable to get tested at the time due to no fever) and experiences similar symptoms described in the article (breathlessness and fatigue). Interestingly, she had a physical in February and all blood work was normal. She went for another check-up in June due to her breathlessness and found that she had hyperthyroidism. Our hypothesis is that her thyroid problem could have been caused by covid. Mentioning in case anyone else has observed this pattern.
