Observing the epidemics of vector-borne diseases is important. One or more cases of 6 vector-borne diseases were reported to the National Epidemiological Surveillance of Infectious Diseases in Japan in 2000-2005.
The reports of those cases were available. The incidence was observed by region of acquired infection, prefecture reporting, and week and year of diagnosis.
The incidence rate per year per 1,000,000 population was 0.36 for dengue fever, 0.04 for Japanese encephalitis, 0.38 for Japanese spotted fever, 0.08 for Lyme disease, 0.74 for malaria, and 3.50 for scrub typhus. There were no cases of dengue fever or malaria derived from domestic infections. The yearly incidence rate increased for dengue fever and Japanese spotted fever, and declined for malaria and scrub typhus. The proportion of cases reported in Tokyo was 44% for dengue fever and 37% for malaria. The number of prefectures reporting one or more cases of Japanese spotted fever increased in western Japan. The cases of scrub typhus increased in autumn-winter in prefectures of eastern Japan, and increased both in autumn-winter and spring in western prefectures.
The study reveals the epidemiologic features of both temporal and geographic distributions of cases of 6 vector-borne diseases in Japan, 2000-2005.
观察虫媒传播疾病的流行情况很重要。2000年至2005年期间，日本国家传染病流行病学监测报告了6种虫媒传播疾病中的1种或多种病例。
可获取这些病例的报告。通过感染获得地区、报告的县以及诊断的周和年份来观察发病率。
每100万人口每年的发病率分别为：登革热0.36、日本脑炎0.04、日本斑点热0.38、莱姆病0.08、疟疾0.74、恙虫病3.50。没有源自国内感染的登革热或疟疾病例。登革热和日本斑点热的年发病率上升，而疟疾和恙虫病的年发病率下降。东京报告的登革热病例占44%，疟疾病例占37%。报告有1例或更多例日本斑点热病例的县的数量在日本西部有所增加。日本东部各县恙虫病病例在秋冬季节增加，而在西部各县秋冬和春季均增加。
该研究揭示了2000年至2005年期间日本6种虫媒传播疾病病例的时间和地理分布的流行病学特征。
