On 22 November, the United States of America - International Health Regulation National Focal Point reported a cluster of influenza like illness cases among three children. Rapid influenza diagnostic tests performed were positive for influenza A. Molecular testing confirmed an influenza triple reassortant (influenza A (H3N2) (SOtrH3N2)) virus, and genomic sequencing confirmed they were S-OtrH3N2 viruses with the M segment gene from the pH1N1 virus. In this regard, the Pan American Health Organization/World Health Organization (PAHO/WHO) would like to stress to its Member States the importance of the recommendations specified in the PAHO-CDC Generic Protocol for Influenza Surveillance.
