Summary

What is already known about this topic?
Japanese encephalitis (JE) virus is a leading cause of encephalitis in Asia. The World Health Organization recommends integration of JE vaccination into national immunization schedules in all areas where the disease is a public health priority.
What is added by this report?
A review of surveillance and immunization program data in the 24 countries with JE virus transmission risk found that in 2016, 22 countries conducted at least some surveillance for JE, and 12 had implemented a JE immunization program. This represents substantial progress in JE prevention and control measures, but challenges remain, including incomplete case reporting, misclassification of cases, lack of immunization program monitoring data, and inadequate monitoring of JE vaccination coverage following vaccine introduction.
What are the implications for public health practice?
Strengthened surveillance, continued commitment, and adequate resources for JE vaccination should help maintain progress toward prevention and control of JE.
