By: None of the children were taken to hospital and each has recovered from a mild episode of febrile respiratory illness.
All three were in contact with one another, and none had a known recent exposure to swine.
No additional human infections with this virus have been detected in Iowa, and no evidence of sustained human-to-human transmission of this S-OtrH3N2 virus exists; surveillance is ongoing.
Eighteen human infections with swine-origin influenza A (H3N2) viruses have been identified since 2009.
The most recent 10 cases, including the three Iowa cases described in this report, were infections with S-OtrH3N2 viruses containing the matrix (M) gene from the pandemic 2009 influenza A (H1N1) virus (pH1N1).
These viruses are considered reassortant viruses between a swine-origin influenza A (H3N2) virus circulating in North American swine and a pH1N1 virus.
