This damn virus certainly targets some far more severe. All science can really do is collect data and report discoveries. There are some predisposition that suggests higher risk? But not all the time.
If this is a test from God as some have suggest? We are not understanding the point. As we rarely do. I guess that's the "Mysterious ways" part?
Oh, it's a test from God alright!! Let's see how many people I can kill off with a deadly virus. It's a test of your immune system. I don't worry so much, I can't even catch a cold or the flu (never had a flu shot). But others aren't so lucky.
