Japanese Encephalitis and Problem in Vector Surveillance: An Introduction

Part of the SpringerBriefs in Animal Sciences book series (BRIEFSANIMAL)


Japanese Encephalitis (JE), a mosquito borne disease, is the leading cause of viral encephalitis in 14 Asian countries. Approximately, 60 % of the world’s population live at risk in JE-endemic regions of these countries. JE is responsible for several hundred deaths in children annually in India, of which >75 % are contributed by Northern India. The disease was first recognised in 1955 and since then many major out-breaks have been reported from different parts of the country, predominantly in rural areas. Case fatality rate has ranged from 10 to 77.5 % and in patients who recover; complication may lead to lifelong disability. In most of these outbreaks from northern India, disease transmission could not be explained in the past due to inadequate mosquito surveillance tool used for determining JE vector density. This chapter briefly traces history of emergence of JE in India and provides a general introduction to “Japanese encephalitis”. The health impact in construction of two canals, viz. Eastern Yamuna Canal and Western Yamuna Canal in Northern India has also been addressed. The problem faced during outbreak investigation of JE/acute encephalitis syndrome (AES) in Northern India is discussed. Author of this book developed a simple, cost effective, operationally feasible JE vector surveillance tool that helped to know all most every aspect of Culex tritaeniorhynchus mosquitoes, principal vector of JE virus in India, and to suggest appropriate vector control measures. These findings are incorporated in  Chaps. 2,  3,  4,  5,  6,  7 of this book.
