So, to reiterate how this works, each Covid infection has a good chance of doing damage to your body, especially to your brain, cardiovascular system and to your immune system, which does not become stronger, but rather disregulated and weakened against future infections, not just of Covid but of other diseases.
This damage may not be symptomatic, in which case you don’t have “Long Covid”, but it’s real. Each time you get re-infected there is a chance of more damage, and I’m almost entirely certain, an increased risk of Long Covid.
Long Covid itself can be mild, or it can be crippling. Millions of people now can’t work as a result and others are suffering and less able to work or to enjoy their lives.
