Which animal is amplifier of Japanese encephalitis?

Correct option is C

Sol. Pigs are known amplifier hosts for Japanese Encephalitis Virus (JEV). They allow rapid multiplication of the virus without falling sick and transmit it to Culex mosquitoes. Humans are dead-end hosts as they don’t spread the virus back to mosquitoes. JE is prevalent in rice field areas where pigs and mosquitoes coexist.
Explanation of each option:
· (a) Cow – Cattle can be infected but don’t play a major role in amplifying JE virus.
· (b) Monkey – Not involved in JE transmission; more relevant for diseases like KFD.
· (c) Pig – Correct. They develop high viremia and help spread the virus to mosquitoes.
· (d) Cat – No role in JE transmission; they are not part of the virus life cycle.
