南阳市１９９５年５起肠道传染病爆发流行，发病１７５９例，回顾性调查了６６８例，五个爆发点罹患率分别在０．１４～３６．９３％之间。六月份为发病高峰月，占调查总病例的８０．０９％；病例主要集中在４０岁以下年龄组，占调查总病例的７７．１０％。采集大便标本２８份，查出２ａ型痢疾杆菌四株；采集血标本九份，肥达氏反应阳性三份。此次爆发流行的主要原因是天旱少雨，人畜共用同一水源，而且水源及周围环境卫生差或者水源没有采取过滤，消毒措施，以及个人卫生习惯不良。同时基层卫生人员上报疫情迟缓，贻误了扑灭疫情的有利时机，因此，构成了疫情爆发的基本条件。
In 1995, 5 epidemics of intestinal infectious disease were reported in Nanyang City, with 1759 cases of onset and 668 cases retrospectively investigated. The attack rates of the five outbreaks were between 0.14 and 36.93% respectively. June peak incidence month, accounting for 80.09% of the total survey cases; cases are mainly concentrated in the age group under 40, accounting for 77.10% of the total surveyed cases. 28 stool samples were collected, and four strains of dysentery bacillus type 2a were detected. Nine blood samples were taken and three of them were positive. The outbreak of the epidemic is mainly due to drought, rain, human and animal share the same source of water, and poor water and the surrounding environment or the water did not take filtering, disinfection measures, as well as poor personal hygiene. At the same time, grass-roots health workers reported a delay in the outbreak of the epidemic, which delayed the favorable opportunity of suppressing the outbreak and therefore constituted the basic condition for the outbreak of the outbreak.
