Influenza A (H3N2) Variant Virus

Posted by Paul

The influenza A (H3N2) virus is labeled as a variant virus because it normally circulates in pigs however it is found in humas as well. Influenza A (H3N2) variant viruses carry the (M) gene that was present in the H1N1 virus from 2009 and human cases involving this virus were first detected in July 2011. The viruses were present in U.S. pigs in 2010. From July to December of 2011 12 cases of the H3N2 virus were detected in the U.S. From January to September of 2012, 307 cases of the H3N2 infection were detected across 12 states. It is believed that these infections occured because of prolonged contact with pigs at agricultural fairs. There have been some cases where human to human contact spread the disease however there has not been a major outbread due to this type of contact. Scientist believe that sporadic outbreaks of this virus will occur due to human to human contact however they will not be sustained. The Centers for Disease Control reccomends covering your nose and mouth when you cough as well as washing your hands with soap and water frequently throughout the day. If soap is not available you can use an alcohol based hand sanitizer. If you become ill stay at home until your illnes is gone in order to prevent infecting your co-workers/classmates.
