CEDAR RAPIDS, Iowa (AP) — Cedar County health officials are stepping up flu surveillance since a child there was diagnosed with a flu virus normally found in pigs. Cedar Rapids television station KCRG-TV reports that the H3N2v influenza A strain was verified by the U.S. Centers for Disease Control and Prevention. State epidemiologist Dr. Patricia Quinlisk says the child, who has since recovered, had not been in contact with swine, one of the modes of transmission.

Quinlisk says health professionals in the Cedar County area are being asked to take more specimens for testing from people who might have the flu. Quinlisk says three Iowa children had the same strain in November 2011. All recovered.
