Parotitis in a Child Infected with Triple-Reassortant Influenza A Virus in Canada in 2007

Abstract

Swine H3N2 influenza virus designated A/Ontario/1252/2007 was isolated from a child with parotitis. Diagnosis was confirmed by viral isolation and serological assays. A/Ontario/1252/2007 was related to H3N2 triple reassortants that emerged in swine in the United States in 1998. Three of five tested household members were also seropositive for A/Ontario/1252/2007.
