Japanese Encephalitis
Japanese encephalitis (JE) is a virus transmitted through the bite of infected mosquitoes. It’s most commonly found in rice fields and other rural areas of Asia.
What is Malaria JE
- High fever
- Disorientation
- Tremors
- Stiff neck
- Convulsions
- Paralysis
According to the Centers for Disease Control and Prevention (CDC), a quarter of people who develop JE will die. Half will develop permanent brain damage. Currently vaccination is only widely available for adults in the United States. The vaccine approved for children is no longer manufactured. If a child needs a vaccine, the options include:
off-label use of the adult vaccine
enrollment in a clinical trial
going to a travelers’ health clinic in Asia
Who Needs Vaccination?
Not everyone who travels to Asia needs to be vaccinated for JE. Vaccination is recommended only for those who are:
going to spend at least one month in an area where JE occurs
planning to visit any rural areas or engage in outdoor activities
visiting an area with a current JE outbreak
uncertain of their travel plans
The vaccine is given in two doses. The doses should be given at least 28 days apart. The second dose should be received at least one week before potential JE exposure. This means you need the first vaccine dose at least 35 days before the start of travel.
How Is Malaria Treated?
Certain people should not get the JE vaccination. This includes people who:
have had a serious reaction to a previous dose of the JE vaccine
are allergic to any vaccine components
are pregnant, except in certain circumstances
Talk to your doctor if you are planning only a short stay in Asia. If you are primarily visiting urban areas, you may not need the vaccine.
