An outbreak of Influenza A virus occurred in a hilltribe village between July 18th and August 8th, 1997. The overall infection rate was 92.5 per cent. The household infection rate was higher in the crowded part of the village. The symptoms analyzed after all, were fever (100%), cough (99%), headache, myalgia (78.1%) and rhinorrhea (50.5%). The patients were self - recovery within 5-7 days. Isolation and Haemagglutination inhibition test (HI) were undertaken to identify the causative agent. The results were positive for influenza A/Wuhan/359/95(H3N2) - like strain. The outbreak did not spread to the town, possibly because of the differences in environmental condition. Predisposing factors of the village that may have influenced the outbreak were crowded living quarters, cold (8 - 10 degrees C) and moist weather, poor personal hygiene and improper sanitation.
1997年7月18日至8月8日期间，一个山地部落村庄爆发了甲型流感病毒疫情。总体感染率为92.5%。村庄拥挤区域的家庭感染率更高。经分析，所有症状为发热（100%）、咳嗽（99%）、头痛、肌痛（78.1%）和流鼻涕（50.5%）。患者在5至7天内自行康复。进行了分离和血凝抑制试验（HI）以确定病原体。结果显示为甲型/武汉/359/95（H3N2）样毒株阳性。疫情未蔓延至城镇，可能是由于环境条件不同。可能影响此次疫情爆发的村庄易感因素包括居住空间拥挤、寒冷（8至10摄氏度）潮湿的天气、个人卫生差和环境卫生不当。
