Japanese Encephalitis (JE) is a major public health problem that is endemic in parts of China, Russian Federation’s South East and South East Asia, where majority of worldwide case are found. Major outbreaks of JE occur every 2-15 years with transmission intensifying during the rainy season when vector population increases. The spread of JE in new areas is often correlated with agricultural development and intensive rice cultivation supported by irrigation programmes.
For those wanting to track the incidence of JE in specific geographical zones, HealthMap, is a credible, freely accessible and automated electronic information system. It monitors, organises and visualises reports of global disease outbreaks as per geography, time, and infectious disease agents. It effectively combines multiple data sources, including online news aggregators, eyewitness reports, expert-curated discussions and officially validated reports to create a comprehensive picture of the state of infectious diseases and their impact on human and animal health in the current global scenario. Delivering real time intelligence data from a broad range of sources including local health departments, libraries, governments and travellers, it is a ‘must have’ tool, especially for those working in complex environments like South Asia.

JE outbreaks are being reported from previously unknown foci. Further, encephalitis outbreaks of other aetiologies in endemic areas have only added to their complexity. For programme managers, researchers and community health professionals, access to accurate and updated information is key to planning interventions and other relief measures.read more
