Detail on first Indiana case (2M):
Case 1 (Indiana)
• A medically fragile male child with multiple co-morbidities became ill with influenza-like
symptoms (fever, cough, congestion, fatigue and diarrhea) on July 23, 2011. The patient has
since returned to baseline health status.
• The child had received influenza vaccine in September 2010, and was not treated with
influenza antiviral medications.
• The child was seen at a local emergency department on July 24, 2011. A nasopharyngeal swab
specimen tested positive for influenza A (H3) and was forwarded to the Indiana State
Department of Health for further testing as part of routine CDC-supported influenza
surveillance.
• Testing at the Indiana State Department of Health identified suspect swine-origin triple
reassortant influenza virus and the specimen was sent to CDC for further characterization.
• This case is the first recognized case of human infection with swine-origin triple reassortant
influenza A (H3N2) virus with the M segment gene from the pandemic 2009 H1N1 virus to
date.
• An International Health Regulation (IHR) report was submitted on August 20, 2011, per the
World Health Organizations reporting requirements in the event of a human infection with a
novel or animal origin influenza virus infection.
• There is no reported contact between the patient and swine in this case. However, a home
health nurse of the child reported frequent swine contact in the weeks prior to his illness
onset.
• The situation in Indiana is suggestive of human to human transmission of this virus. No
additional illness was identified in the caretaker, her family or close contacts, or the pigs she
contacted.
