Altogether 13 strains of virus were isolated during the 1974 influenza epidemic in Nigeria. These A/Nigeria/1/74 strains were shown by haemagglutination-inhibition tests to be closely related to the A/Port Chalmers/1/73 virus. Antibody to the epidemic strains developed rapidly in the population and 80-95% of all age groups tested possessed high antibody levels; of 145 paired sera tested, 133 (92%) showed sero-conversion to A/Nigeria/1/74 virus.
1974年尼日利亚流感疫情期间共分离出13株病毒。血凝抑制试验表明,这些A/尼日利亚/1/74毒株与A/查尔姆斯港/1/73病毒密切相关。人群中针对流行毒株的抗体迅速产生,所有接受检测的年龄组中有80 - 95%的人拥有高抗体水平;在检测的145对血清中,133对(92%)显示出对A/尼日利亚/1/74病毒的血清转化。
