Regarding morbidity, research on "long COVID" (long-term disability associated with COVID) is still scarce, but here are abbreviated results from two studies:What is the overall risk of serious morbidity or mortality from COVID for an individual who is not in a high risk group?
- Among 3700 COVID patients from 56 countries, 65% reported the following symptoms most commonly for at least six months: fatigue, post-exercise malaise, "brain fog," neurological sensations, headaches, memory issues, muscle aches, insomnia, heart palpitations, shortness of breath, balance issues, and speech issues.
- More than 75% of 1733 COVID patients discharged from a hospital in Wuhan had at least one symptom six months later, including fatigue, insomnia, depression, anxiety, and diminished lung function.
Neither study focused on patients in high-risk groups or not in high-risk groups.
Anecdotally, I've seen dozens of reports of long-term COVID-related disability among patients not in high-risk groups.
