As with "most" "world" organizations, (like the UN, NATO,) I have reservations to the overall validity of their "opinion". Re: World Health Organization.
91 cases in the United States out of 300+million, is a statistical nothing.
PLUS, most of the cases here in the U.S. are recovering. The 8 kids in the school in NY, are all going to survive. The 23month old child came across the border sick and than died. (Not really an American fatality yet,..)
This "bug" responds to Tamiflu and Relenza which, in otherwise healthy people, is treatable.
Can it get worse? Sure, I won't doubt that, although the flu season is waning with the approach of summer. I did hear from a talking head that it may come back this fall/winter if not tamped down now.
We prepare, stay in touch, and I guess hand sanitizers will become more popular. All good advice.
I am hoping for the best.
