In April, 2009, an outbreak of Swine Flu was reported, first in Mexico, and then immediately after other countries as well, giving every indication of a possible pandemic.  The [[Centers for Disease Control and Prevention]] said the [[Mexico|Mexican]] virus samples match the [[U.S.]] virus. ''The virus is a mix of human virus, bird virus from [[North America]] and pig viruses from North America, [[Europe]] and [[Asia]].''  The CDC recommends the use of the flu drugs Tamiflu and Relenza, as there isn't a specific vaccine for the current mutated strain. <ref>[http://www2a.cdc.gov/podcasts/player.asp?f=11226 CDC Podcast]</ref> It is genetically different from the fully human H1N1 seasonal influenza virus that has been circulating globally for the past few years.
