• Description:
  During May 21-September 23, 2017,* the United States experienced low-level seasonal influenza Virus activity; however, beginning in early September, CDC received reports of a small number of localized influenza outbreaks caused by influenza A(H3N2) Viruses. In addition to influenza A(H3N2) Viruses, influenza A(H1N1)pdm09 and influenza B Viruses were detected during May-September Worldwide and in the United States Influenza B Viruses predominated in the United States from late May through late June, and influenza A Viruses predominated beginning in early July. The majority of the influenza Viruses collected and received from the United States and other countries during that time have been characterized genetically or antigenically as being similar to the 2017 Southern Hemisphere and 2017-18 Northern Hemisphere cell-grown vaccine reference Viruses; however, a smaller proportion of the circulating A(H3N2) Viruses showed similarity to the egg-grown A(H3N2) vaccine reference Virus which represents the A(H3N2) Viruses used for the majority of vaccine production in the United States Also, during May 21-September 23, 2017, CDC confirmed a total of 33 influenza Variants Virus| infections; two were influenza A(H1N2) Variants (H1N2v) Viruses (Ohio) and 31 were influenza A(H3N2) Variants (H3N2v) Viruses (Delaware 1, Maryland 13, North Dakota 1, Pennsylvania 1, and Ohio 15). An additional 18 specimens from Maryland have tested presumptive positive for H3v and further Analysis is being conducted at CDC.
