Abstract

Hemagglutination-inhibition tests were car ried out in 651 human sera for the dctection of antibodies to type C influenza virus. Of 324 and 327 sera collected respectively in 1978 and 1979, from individuaIs without evidence of respiratory infection, 68.6% showed positive results. There was no important
difference between the two years, except in the 0-4 year age group and in persons older than 60 years. In these two age groups, the frequency of positive
findings was 15.3% and 53.3%, respectively for the 1979 sera while in the 1978 sera, the frequency was 33.3% and 75.0%, respectively.
