Experiences with
EncephalitisSymptoms of encephalitis
Encephalitis usually starts off with flu-like symptoms, such as a high temperature and headache.
More serious symptoms come on over hours, days or weeks, including:
- confusion or disorientation
- seizures or fits
- changes in personality and behaviour
- difficulty speaking
- weakness or loss of movement in some parts of the body
- loss of consciousness
Dial 999 for an ambulance immediately if you or someone else has these serious symptoms.
Treatments for encephalitis
Encephalitis needs to be treated in a hospital. The earlier treatment is started, the more successful it's likely to be.
Treatment depends on the underlying cause, but may include:
- antiviral medicines
- steroid injections
- treatments to help control the immune system
- antibiotics or antifungal medicines
- painkillers to reduce discomfort or a high temperature
- medicine to control seizures or fits
- support with breathing, such as oxygen through a face mask or a breathing machine (ventilator)
How long someone with encephalitis needs to stay in hospital can range from a few days to several weeks or even months.
Preventing encephalitis
It's not always possible to prevent encephalitis, but some of the infections that cause it can be prevented with vaccinations.
These include the:
- measles, mumps and rubella (MMR) vaccine – a routine vaccination offered to all children in England
- Japanese encephalitis vaccine – recommended for travellers to at-risk areas, such as parts of Asia
- tick-borne encephalitis vaccine – recommended for travellers to certain parts of Europe (but not the UK) and Asia
- rabies vaccination – recommended for travellers to at-risk where access to medical care is likely to be limited. Find out about rabies risks in terrestrial animals by country on GOV.UK.
Speak to a GP surgery if you're not sure whether your vaccinations are up to date, or you're planning to travel abroad and do not know if you need any vaccinations.
