2011-2012 Influenza Season Week 30 ending July 28, 2012
All data are preliminary and may change as more reports are received.
Novel Influenza A Virus:
Twelve human infections with novel influenza A viruses were detected in three states (Hawaii [1], Indiana [1], and Ohio [10]). The 12 persons were infected with influenza A (H3N2) variant viruses similar to those identified in cases that occurred previously in 2011 and 2012. At this time no ongoing human-to-human transmission has been identified and all 12 cases have reported close contact with swine prior to illness onset. While the viruses identified in these cases are genetically related, separate swine exposure events in each state are associated with infection and there is no indication that the cases in different states are related. Public health and agriculture officials are investigating the extent of disease among humans and swine, and additional cases are likely to be identified as the investigation continues.
CDC is required to report all cases of human infection with novel (non-human) influenza viruses – including influenza viruses of swine origin – to the World Health Organization (WHO)
as part of the International Health Regulations (IHR). Domestically, CDC reports these cases in this report and on its website. Early identification and investigation of human infections with novel influenza A viruses is critical in order to evaluate the extent of the outbreak and possible human-to-human transmission. Additional information on influenza in swine, variant influenza infection in humans, and strategies to interact safely with livestock can be found at http://www.cdc.gov/flu/swineflu/influenza-variant-viruses-h3n2v.htm.
