A year-round study of the infection rates of JE virus in Culex mosquitos was made during 1970-71 in 2 hamlets in Taoyuan County, China (Province of Taiwan). JE virus was recovered from 5 of 314 pools of C. annulus, and from 1 of 22 pools of C. tritaeniorhynchus; these recoveries occurred during a 14-day period in July 1971. None of the 288 pools of C. p. fatigans, which had been collected between October and April, was positive. In addition, sentinel swine were assessed for antibody and virus. All the pigs became highly immune by 23 July; in each hamlet all the pigs had become infected within 1 week, virus being detected in them for only 1-2 weeks. Virus-positive mosquitos appeared to have obtained their infections at about the time that viraemia was occurring in the sentinel swine. These observations illustrate once again the lower infection rate and shorter duration of virus-positive mosquitos in China (Province of Taiwan) as compared with Japan.
1970 - 1971年期间，在中国台湾省桃园县的两个村庄对库蚊中乙脑病毒的感染率进行了全年研究。从314池环带库蚊中的5池以及22池三带喙库蚊中的1池分离出了乙脑病毒；这些分离是在1971年7月的14天期间发生的。10月至4月间采集的288池致倦库蚊均未呈阳性。此外，对哨兵猪进行了抗体和病毒检测。到7月23日所有猪都产生了高度免疫力；在每个村庄，所有猪在1周内都受到了感染，病毒在它们体内仅被检测到1 - 2周。病毒阳性的蚊子似乎是在哨兵猪出现病毒血症时感染的。这些观察结果再次表明，与日本相比，中国台湾省病毒阳性蚊子的感染率较低且持续时间较短。
