Japanese Encephalitis and the Importance of Vaccination

Japanese encephalitis (JE) is a serious and potentially life-threatening viral infection that is endemic to parts of Asia and the Western Pacific. It is transmitted to humans through the bite of an infected mosquito, primarily the Culex species. This blog aims to provide comprehensive information about Japanese encephalitis, the significance of the Japanese encephalitis vaccine, and guidance on who should consider getting vaccinated, particularly for travellers visiting endemic regions.

What is Japanese Encephalitis?

Japanese encephalitis is caused by the Japanese encephalitis virus (JEV), a flavivirus closely related to dengue, yellow fever, and West Nile viruses. While most infections are asymptomatic or result in mild symptoms, approximately 1 in 250 infections leads to severe disease characterised by inflammation of the brain (encephalitis). Symptoms of severe Japanese encephalitis include:

– High fever
– Headache
– Neck stiffness
– Disorientation
– Seizures
– Coma

Severe cases can result in permanent neurological damage or death. The mortality rate for those who develop encephalitis can be as high as 30%, and 30-50% of survivors may experience long-term neurological sequelae.

Transmission and Risk Areas

The primary vectors of Japanese encephalitis are Culex mosquitoes, which breed in water-rich environments like rice paddies and irrigation channels. The virus is maintained in a cycle between mosquitoes, pigs, and wading birds. Humans are incidental hosts and do not contribute to the transmission cycle.

Japanese encephalitis is endemic to many parts of Asia, including India, China, Japan, Southeast Asia, and parts of the Western Pacific. Travellers to these regions, particularly rural areas with rice fields and pig farms, are at higher risk.

Japanese Encephalitis Vaccine

Vaccination is the most effective way to prevent Japanese encephalitis. The Japanese encephalitis vaccine is an inactivated virus vaccine that provides long-lasting immunity against the virus.

Who Should Get the Japanese Encephalitis Vaccine?

The Japanese encephalitis vaccine is recommended for:

Travellers to Endemic Areas: Individuals planning to travel to regions where Japanese encephalitis is prevalent, especially if they will spend extended periods in rural areas, engage in outdoor activities, or visit during the transmission season (typically the rainy season).

Long-term Travellers and Expatriates: Those who will be living in endemic regions for an extended period should consider vaccination, even if they primarily reside in urban areas.

Laboratory Workers: Individuals working in laboratories with potential exposure to the Japanese encephalitis virus.

Residents of Endemic Areas: In endemic regions, children and adults who live in areas with high transmission rates may be advised to get vaccinated.

For residents of Swindon considering travel to areas where Japanese encephalitis is common, it is crucial to get vaccinated well in advance. The typical vaccination schedule involves two doses administered 28 days apart, with the second dose completed at least one week before travel.

Wear Protective Clothing: Wear long-sleeved shirts, long pants, and socks, particularly during dawn and dusk when mosquitoes are most active.

Use Mosquito Nets: Sleep under an insecticide-treated bed net, especially if staying in accommodations without screened windows or air conditioning.

Stay in Air-conditioned or Well-screened Rooms: Ensure that accommodations have proper mosquito control measures.
