Introduction

Japanese encephalitis (JE) is a viral infection that can lead to serious neurological complications. It is transmitted through the bite of infected mosquitoes, primarily in rural areas of Asia and the western Pacific. For travellers from the UK, particularly those visiting regions where the disease is endemic, understanding the need for the Japanese encephalitis vaccine is essential. At Edinburgh Travel Clinic, we provide comprehensive vaccination services to ensure your health and safety while travelling.

Understanding Japanese Encephalitis

What is Japanese Encephalitis?

Japanese encephalitis is a viral infection that affects the brain and can cause severe illness, including inflammation of the brain (encephalitis). Symptoms can range from mild flu-like signs to severe neurological issues, including seizures and coma. The disease is particularly concerning for travellers who may be exposed to mosquitoes in rural areas where the virus is prevalent.

How is Japanese Encephalitis Transmitted?

The primary vector for Japanese encephalitis is the Culex mosquito, which breeds in rice paddies and other stagnant water sources. The virus is not transmitted from person to person; rather, it cycles between mosquitoes and pigs or birds. Travellers are at risk when they visit areas where the virus is endemic, especially during the rainy season when mosquito populations are high.
