Just one person but i was an early case (family member went to Wuhan 1-2 times each month. During the firsr year of COVID, as early as march of 2020, i had serious issues with gut and hearth inflamation - repeated bouts that started as back pain, became chest pain, elevated heart-rate to 150 for ~3 days at a time, 24 hours a day. Gradyally the episodes became less frequent leading up to a stroke type event co current with a presumed second bout of covid. Was forced back to work about a week after the issue, and the only other coworker who was near me contracted covid about 10 days later.

Following the Stroke type event I lost virtually all of my talent at writing, And ultimately my job, which was very humbling. Ive spent the past year working gig jobs when i can, and fortunately all long covid symptoms have gone away. I feel like my brain is close to 100% but i lack the confidence in myself, my memory, and my writing and am constantly second guessing myself and assume im wrong if in a contested discussion. It really sucks, yet im probably one of the lucky ones

Finding this out would require doing mass exploratory surgery on asymptomatic people, which is obviously unethical, because it would kill a substantial number of them and damage all of their hearts.
