1990 Vol.6 NO.4
Japanese encephalitis is an infectious disease of high frequency in Taiwan Area. It was, therefore, made a reportable disease in 1955. The incidence rate per 100,000 population of reported cases in 1967 was 7.66. The Government began the mass immunization of children under two years of age in 1968, the number of reported cases declined sharply thereafter, and leveled off since 1975. Since 1986, the incidence rate of confirmed cases has declined, particularly so in 1989 as shown in Figure 1.
