Why didn't all of you spread the disease to everyone else in the neighborhood?
No different than the "clinical latency" stage of HIV where nothing happens for a decade until your immune system weakens and then a benign opportunistic infection causes you problems. Here it just happens a lot faster - while this coronavirus is also executing other functions in multiple different organs.
This leads to the possibility that there are other seasonal but otherwise benign viruses and bacteria that are prevalent, while this coronavirus is also spreading.
Is that really as much of a farfetched idea if everyone has been looking a different direction? Just harder to resolve and an area to put some energy and research.
