It’s just a respiratory virus, but it’s the leading cause of deaths in babies. It’s bad for the elderly too.
My 27 yr old twin daughters almost died of it when they were 6 weeks old. One has a brain injury from it.
Basically, if you are sick with a respiratory illness and it’s not flu or Covid, it’s a good chance it’s RSV.
Thanks for the info. Sorry you and your daughters were so profoundly effected by it.
