CDC reports H1N2v flu case in Wisconsin
In its weekly flu update on Sep 16, the Centers for Disease Control and Prevention (CDC) reported two more variant H1N2 (H1N2v) infections, in Michigan and Wisconsin.
The case in Michigan is presumably the one announced earlier in the week by Michigan health officials, which involved a child who had contact with pigs at the Berrien County Youth Fair. The CDC report said that investigators found that a household contact of the patient had a respiratory illness.
The child had attended the same agricultural fair and was sick at the same time as the patient with the confirmed H1N2v infection. The CDC said no person-to-person transmission of the virus has been identified.
Meanwhile, the CDC said the patient in Wisconsin is also younger than 18 and that the investigation is still ongoing.
The two infections push the nation's number of variant flu infections this season to seven in five states. Five have been linked to H1N2v, and two were due to H3N2v. Last month, the CDC issued a health advisory that asked providers to monitor for variant flu illnesses and warned that it expected more cases during agricultural fair season.
