Seems like every last continental state of US is having it. No doubt it spreads from US all over the world through all the air lines. Currently available flu shot in UK is only 20% effective against the virus (H3N2), they say. Alabama state already declared emergency about it. Expected death toll by the end of it - for now, and in US only - is ~50000. It kills primarily elderly people (about 2/3s of all death cases), but also people of all other ages now and then. Already dead are at least: 110 persons in Canada, 97 persons in California state alone (i fail to see data for whole US, but obviously it'd be several hundreds to thousands deaths already), 191 persons in UK. Several millions people are also infected in Japan and also in China, too - i assume similar to the above fatality numbers happen there as well. Other countries are also hit, such as Spain, Germany, Italy, Portugal, and some countries in South and Central Americas, Asia and Europe, according to this map. Do not feel safe if your country is not listed as one affected on the map just above, though. It takes a long time for reported cases to be verified and that map updated. We have one global flu epidemic here, which right now may be lurking right near your and yours. and this time it is especially efficient at infecting people all around - for example, this is 1st time in modern history of CDC operations (in 13 years) they see whole continental US suffering epidemic rates of this flu. Thus i dare to give one advice you won't hear much (if at all), which can easily save your and/or yours lives, and is extremely very easy to follow: remember that amount of viruses which enter your system is critically important in determining whether you get sick or not, and whether you live or die if you get sick! Therefore try to limit your inhalation of potentially infected particles by: - leaving vicinity of any coughing person ASAP; - going outside whenever possible and staying at least several meters (and not downwind) from any potentially infected person; - wearing respiratory protection devices whenever you suspect any infected person is (or recently was) nearby; - isolating yourself as much as possible whenever you detect any flu-like sympthoms in yourself; - spread this knowledge to yours (your family, friends, peers and such). P.S. The fact that amount of virus entering someone's system is something i repeatedly concluded from various papers and books related to virology, but if you want concrete example - here you go, quote: "the route and volume of virus administered to mice ... can greatly influence the resulting morbidity and mortality following infection, especially when studying highly pathogenic avian influenza (HPAI) viruses".
