| Summary: | Serological surveys have contributed significantly to epidemiologic assesments of influenza. Serological surveys of persons in different ages have contributed to knowledge about immune responses to influenza viruses and have provided information about possible recycling of the influenza A subtypes. Although a variety of procedures have been used, the hemagglutinin inhibition (HI) test has been used most often for this purpose because the antibody measured is durable and is directed toward a surface glycoprotein exhibiting antigenic variation, the hemagglutinin, that is most relevant for assessing immunity and susceptibility. To detect influenza viruses circulating in Ankara in 1996-97 influenza season antibodies to influenza viruses were studied by HI method in blood sera of 106 healthy and unvaccinated persons of age group 20-50. Antibody titers above 1/20 to A/Taiwan 1/86 (H1N1), A/Johannesburg 33/94 (H3N2), A/Wuhan 359/95 (H3N2), B/Be›-j›ng 184/93, B/Guangdong 8/93 were positive in 84%, 75%, 21%, 53%, 100% on this group respectively. Considering these findings it was concluded that persons of age group 20-50 had exposed to aforementioned influenza virus strains and susceptible persons to influenza should be vaccinated with influenza vaccines containing especially those strains. |
