Ang '''pandemyang [[Bayrus trangkaso A subtipo H1N1|Influenza A (H1N1)]]''' ay isang epidemya ng isang flu virus na natuklasan lamang noong Abril 2009, kilala ito bilang "[[trangkasong baboy]] (swine flu)". Ang pinagmulan ng pagkalat nito sa mga tao ay hindi pa rin nalalaman. Ang mga kasong unang natuklasan sa E.U. at ang mga opisyales ay nagsuspetya na may kaugnayan ang pangyayaring ito sa mga naunang pagsilakbo ng sakit na katulad ng trangkaso sa Mehiko. Ilang araw ang lumipas at daang-daang kaso ang naitala sa Mehiko, ilan sa mga kasong ito ay malala, pati na rin ang E.U. ay nakapagtala ng mga kaso at ilang pang mga bansa sa hilagang kalahati ng mundo. Hindi nagtagal mula noon, ang [[Samahan ng Pandaigdigang Kalusugan|S.P.K.]] ng [[United Nations|U.N.]], kasama ang C.D.C ng E.U. ay nagpahayag na ang A(H1N1) ay maaring maging pandaigdigang sakit, at ang S.P.K. ay itinaas na sa "Ika-5 Antas" na hanggang anim ang kahandaan para sa naturing na sakit, bilang "''signal that a pandemic is at the imminent level''".

== Kasaysayan ng konteksto ==

Ang taunang pagkakaroon ng trangkaso ay tinatayang nakakaapekto ng 5–15% ng populasyon sa daigdig, na nagreresulta ng malalalang sakit sa 3-5 milyong tao at nagdudulot ng pagkamatay ng 250,000–500,000 katao sa mundo. Sa mga industrialisadong bansa nagkakaroon lang ng malalang sakit at kamatayan dulot ng trangkaso sa mga matataong lugar at higit na naapektohan ang mga sanggol, matatanda, at mga sakiting tao.<ref name="WHOreports">{{cite web|url =http://www.who.int/mediacentre/factsheets/2003/fs211/en/|title =Influenza|accessdate =2009-05-16|author =Samahan ng Pandaigdigang Kalusugan|authorlink =Samahan ng Pandaigdigang Kalusugan|year =2003|month =Marso|publisher =S.P.K.|pages =1|language =Ingles|archive-date =2009-05-05|archive-url =https://web.archive.org/web/20090505070146/http://www.who.int/mediacentre/factsheets/2003/fs211/en/|url-status =dead}}</ref>

Bukod sa mga taunang epidemya ito, ang bayrus na Influenza A ay nagdulot ng pandaigdigang pagkalat ng sakit noong ika-20 na siglo: Ang trangkasong Hispano noong 1918, trangkaso sa Asya noong 1957 at ang trangkasong Hongkong noong 1968-69. Ang mga sakit na ito ay mula sa bayrus na Influenza A na sumailalim sa malaking prosesong pagbabago na pang-genetiko, dahil sa hindi pagkakaroon ng immunidad sa bayrus.<ref name="WHOreports" /><ref name="CDC">{{cite web|url=http://www.cdc.gov/ncidod/EID/vol12no01/05-1254.htm|title=Influenza Pandemics of the 20th Century|accessdate = 2009-05-16|author =Edwin D.
