Confirmation of Japanese Encephalitis as an Endemic Human Disease Through Sentinel Surveillance in Indonesia

Japanese encephalitis (JE) results in significant mortality and disability in children in Asia. In Indonesia, despite recognition of JE virus transmission, reports of human disease have been few and from limited geographic areas. Hospital-based surveillance for acute encephalitis syndrome (AES) and JE in children 15 years of age and under was undertaken in 15 hospitals in 6 provinces from 2005 to 2006. High- and low-risk provinces in geographically dispersed areas were included. Health center-based surveillance was also undertaken in one province. Eighty-two JE cases were confirmed among 1,496 AES cases detected. JE cases were confirmed in all provinces, but the proportion varied between 2 and 18 percent among provinces of different risk levels. Children younger than ten years of age represented 95 percent of JE cases, and 47 percent of all cases either died or were disabled. The study, published in The American Journal of Tropical Medicine and Hygiene, shows JE is an endemic human disease across Indonesia.
