Influenza A(H3N2) Virus Isolations -- United States

Type A(H3N2) influenza virus, isolated in Alaska earlier this season (1), has now been isolated from a woman in New York City, an infant in Oregon, and a 4-year-old child who became ill after returning to Virginia from Hawaii. The woman, a 26-year-old resident of New York City, had onset of influenza on November 17. She had not recently traveled outside the metropolitan area. The male infant, who lived in Corvallis, Oregon, had onset on November 2 of an illness initially suspected to be caused by enteroviral infection. The 4-year-old had returned to Virginia with his family on October 19, after a 7-day vacation to Honolulu, and developed high fever, cough, and malaise on October 20. His illness worsened, and he was lethargic when admitted to a District of Columbia hospital on October 22. The child improved rapidly and was discharged on October 26. On October 18, just before departing from Hawaii, the child's mother had onset of influenze-like illness, and a younger sister had an influenza-like illness concurrent with her brother, but specimens for virus isolation were not collected from either.

Public health officials representing the jurisdictions where these three cases occurred have not reported indications of increased influenza-like illnesses.
