“…The 18 sera from the young adult group were all antibodypositive (data not shown). This pattern of age distribution of the antibody was well comparable with the results obtained previously using HI tests for serological surveys (1,(4)(5)(6)(8)(9)(10)(11). In Table 1, the results of RIP tests are compared between Kadaklan and Yamagata.…”

A total of 101 serum samples were collected from the persons (1 to 85 years of age) living in a Philippine mountain village where the contact with other communities has largely been restricted. These sera were tested for the presence of antibody to influenza C virus with hemagglutination-inhibition and radioimmunoprecipitation tests. The results showed that all the subjects, including the persons who had never been outside the village, contained the antibody to the surface glycoprotein of the virus, and that the age of acquisition of the antibody was significantly lower in this village than in any of the previously studied communities. Thus it appeared that infection with influenza C virus was prevalent even in this small mountain village, presumably with a higher incidence than in the larger, industrialized communities.

“…Seroepidemiological studies have revealed that influenza C virus is widely distributed throughout the world (2)(3)(4)(5)(6), and recurrent infection with this virus occurs frequently in children and adults (7). However, the virus has been isolated by cell culture only occasionally, and long-term monitoring of influenza C viruses is rarely conducted.…”

Isolation and Characterization of Influenza C Viruses in the Philippines and Japan

in the Philippines, 15 influenza C viruses were isolated, using MDCK cells, from specimens obtained from children with severe pneumonia and influenza-like illness (ILI). This is the first report of influenza C virus isolation in the Philippines. In addition, from January 2008 to December 2013, 7 influenza C viruses were isolated from specimens that were obtained from children with acute respiratory illness (ARI) in Sendai city, Japan. Antigenic analysis with monoclonal antibodies to the hemagglutinin-esterase (HE) glycoprotein showed that 19 strains (12 from the Philippines and 7 from Japan) were similar to the influenza C virus reference strain C/Sao Paulo/378/82 (SP82). Phylogenetic analysis of the HE gene showed that the strains from the Philippines and Japan formed distinct clusters within an SP82-related lineage. The clusters that included the Philippine and Japanese strains were shown to have diverged from a common ancestor around 1993. In addition, phylogenetic analysis of the internal genes showed that all strains isolated in the Philippines and Japan had emerged through reassortment events. The composition of the internal genes of the Philippine strains was different from that of the Japanese strains, although all strains were classified into an SP82-related lineage by HE gene sequence analysis. These observations suggest that the influenza C viruses analyzed here had emerged through different reassortment events; however, the time and place at which the reassortment events occurred were not determined.

“…Influenza C viruses cause a mild upper respiratory tract disease (Dykes et al, 1980;Katagiri et al, 1983Katagiri et al, , 1987 and are widespread in the human population (Minuse et al, 1954;Andrews & McDonald, 1955;Jennings, 1968;Homma et al, 1982;Kaji et al, 1983). Little is known, however, about the mode of transmission and maintenance of the virus in nature although some investigators have assumed that the natural reservoir of the virus is limited to man (Air & Compans, 1983).…”
