The JEV transmission cycle comprises the Culex tritaeniorhynchus or Culex vishnui mosquito species as vector which breed in stagnant water of rice fields where they encounter birds that serve as replicating hosts along with pigs. However, transmission of JE is likely to increase in Bangladesh, Cambodia, Indonesia, Laos, Myanmar, North Korea, and Pakistan because of population growth, intensified rice farming, pig rearing, and the lack of vaccination programs and surveillance. Vaccination is often recommended for travelers, especially if they expect lengthy stays in rural endemic areas (where the disease occurs consistently within a specific region/locality). Transmission to humans requires mosquito species capable of creating a "bridge" between infected animals and uninfected humans; this occurs when … Among those travelers who are infected with a JEV-bearing mosquito bite, only one in 50 to one in 1,000 will become ill with JEV.
