Isolation of influenza C virus during an outbreak of influenza A and B viruses.
During the winter of 1996 to 1997 two cases of influenza C were confirmed, one by isolation and the second by serology (fourfold increase in hemagglutination inhibition antibodies). The cases of influenza C occurred during an outbreak of influenza A (H3N2) and B viruses. The positive isolation was from one of three throat washings sent to the laboratory, and the other case was from a group of 51 students participating in a study of influenza virus vaccination. It seems, therefore, that influenza C virus should also be considered when examining patients with respiratory infections during the influenza season.
