Japanese Encephalitis in Vietnam : What You Need to Know
The first case of Japanese encephalitis this year was recorded in Hanoi: a 13-year-old boy received three basic doses of the vaccine. He is currently in serious condition, but did not receive a booster.
Japanese encephalitis is a virus transmitted by mosquito bites. In Vietnam, Japanese encephalitis is not uncommon. Previously, there were so many cases, that mass vaccinations of children were launched. The incidence rate dropped significantly, but the virus has not disappeared.
For most people, it's a mild cold or nothing at all. But if the virus reaches the brain, things are dire: high fever, confusion, seizures, and paralysis are guaranteed.
Does everyone need to get vaccinated urgently? No. But it's at least a disease worth considering if you plan to live near Hanoi for many months, traveling through villages, and taking children there. Those most at risk are those who live or are stuck in rural areas, even near major cities, as well as those near rice fields and pig farms.
