If only there were some kind of Centre for Virus Control....I'll let you do the searching, but there's indications that those cases may be related to HPV / exposure to other viral pathogens. Because of this fact, I try to limit my exposure to second hand viruses (SHV) and believe viral outbreaks should be banned immediately.
Yeah, I've read some of the stuff that CarolT(I think?) posts. A lot of it makes sense. I don't know if EVERYTHING can be explained that way but likely a lot of it can. There's also the fact that we've basically doubled our lifespan, that's bound to lead to some unforeseen consequences.
