You can say that's the message, but people won't listen to your message. I almost decided not to bother getting the rapid and just go to the sheva brachos because rapids are "not accurate".
First of all, R"S to you and your family. Second, you realize that it wasn't accurate for you, and the nes here is that it caught your wife's infection, keeping you from going to the sheva brachos. That doesn't make rapids any more accurate. It was 50/50 in your own family. That people won't listen to the message of staying home and not going to simchos when you could possibly be sick, with Covid or anything else, doesn't make rapids a blessing. It makes people stupid.
(Sorry if that was a bit blunt.)
