During the course of continuous surveillance of influenza in 1980 in Pune, India, which has a tropical monsoon climate, three outbreaks of acute respiratory infection (ARI) were investigated in March (hot season), in July-September (rainy season), and in November (cold season); sporadic cases during the interepidemic months were also studied. The first outbreak was associated with influenza A virus (H3N2), the second with influenza A viruses (H3N2) and (H1N1) and influenza B virus, but fewer influenza viruses were isolated during the third outbreak. The illnesses affected all age groups including infants and adults over 60 years of age, although the paediatric age group was mainly affected. The ARI outbreaks associated with the hot and cold seasons commenced at about the time the weather changed whereas the mixed influenza A (H3N2) and A(H1N1) outbreaks occurred in the middle of the rainy season.
1980年，在印度浦那（属热带季风气候）持续开展流感监测期间，对3月（炎热季节）、7月至9月（雨季）和11月（寒冷季节）发生的3起急性呼吸道感染（ARI）疫情进行了调查；还对流行间期的散发病例进行了研究。首次疫情与甲型流感病毒（H3N2）有关，第二次与甲型流感病毒（H3N2）和（H1N1）以及乙型流感病毒有关，但第三次疫情期间分离出的流感病毒较少。这些疾病影响了所有年龄组，包括婴儿和60岁以上的成年人，不过主要受影响的是儿童年龄组。与炎热和寒冷季节相关的ARI疫情大约在天气变化时开始，而甲型流感（H3N2）和甲型（H1N1）混合疫情则发生在雨季中期。
