Novel Influenza A Surveillance and Reporting Guidance for Sentinel Providers

Human infections with a novel strain of influenza A H3N2 have been identified in 11 people across 5 states: West Virginia (1), Indiana (2), Pennsylvania (3), Maine (2), Iowa (3). Most case have been mild illness, but three of were hospitalized for influenza; all have recovered. Novel H3N2 originated in pigs, and combines genes from swine, avian, and human influenza viruses, including the 2009 H1N1 influenza A virus. Epidemiology of the identified novel H3N2 clusters is suggestive of person-to-person transmission   

These novel influenza H3N2 viruses are substantially different from currently circulating seasonal (human) influenza A H3N2 viruses, and they are distantly related to human influenza viruses that circulated among people in the 1990s.  For that reason, it appears that children elementary age and younger may have a higher likelihood of contracting this strain than older individuals who may have some existing partial immunity  

In order to enhance our surveillance, the Bureau of Epidemiology has released new guidance for influenza specimen submission for sentinel providers. This new guidance is intended to increase the submission of specimens taken from children. Below are guidance documents for each type of sentinel provider in Florida: Influenza Incidence Surveillance Project (IISP) providers, ILINet Super-Sentinel providers, and ILINet providers. This guidance is for surveillance purposes, and is only intended for registered sentinel providers.
