And other researchers/doctors (? sorry, memory lapse) say our immune system is dysregulated, with parts of it overactive and other parts underactive.
I also wonder if the type of virus makes a difference? That as a group - or as individuals - we are more resistant to some viruses and less to others?
For myself I can't comment on the current corona virus because, as far as I know, the nearest case to me was an hour's drive away and I don't think anybody can cough or sneeze quite that far.
However, as far as ordinary colds go, I don't get them very often. Even during the periods I was almost fully fit I never caught them from casual contacts when out and about. I probably picked up 1 out of 3 that my husband dragged home so it took some heavy and persistent exposure for me to get infected. Haven't had any colds at all since my ME turned severe but that could just be because my husband has become a lot more careful about not infecting me with anything.
There've only been 2 occasions in my life I had a bad virus (presumed virus, not actually tested). After the first I came down with ME. After the second, decades later, my ME, very mild at the time, took a big turn for the worse.
So while I don't catch viruses very often, when I do catch one it's bad news.
And then there are the much much much too frequent herpes virus reactivations (cold sores). Clearly my immune system can't deal with those at all.
Overall it looks to me as though our immune system is messed up but whether that translates into better or worse resistance to this virus or that in an individual probably depends on a whole lot of other individual factors. Complicamated
