Indiana covering IA outbreak in its week 46 report
Routine influenza surveillance in Iowa indicated a novel influenza virus in three children in North Central Iowa. This influenza A (H3N2) recombinant virus has also been detected in other states in recent months. The virus contains components of human, avian, and swine influenza viruses, as well as components of influenza A (H1N1) virus. All transmission has been human-to-human, and transmission appears to be limited. No additional cases have been identified in the last week. None of the ill persons has had any known exposure to animals. No serious illnesses or deaths associated with this novel influenza A (H3N2) virus have been reported, and all ill persons have recovered. Surveillance for this virus has been enhanced at clinics and emergency rooms in the area.
Two human infections with novel influenza A viruses were detected in individuals from Indiana. Both patients were infected with swine-origin influenza A (H3N2) viruses. Both were hospitalized but have been discharged and both have recovered from their illnesses. One case was hospitalized in July, 2011 and one in October, 2011. There has been no evidence of an epidemiological link between these two patients and no sustained human-to-human transmission of these viruses has been found.
