Some sources are saying the surge is due to covid quarantining and the like over the last 2 years. This prevented the normal number of children from getting exposed to RSV. Now they are and it's spiking.
You have a very good point. Just imagine the native Americans without immunity or treatments when probably similar viruses came over from which they had no or little immunity. There was the virus smallpox of course but other pathogens. There was no malice. They just didn’t know. It happened.
There’s sort of a normal ebb and flow of these viruses in a typical population where people develop a herd immunity according to the experts. After isolation of our children I could see this happening.
Prayers for the kiddos.
