What causes encephalitis?
Encephalitis can be caused by a viral infection, bacterial infection, or autoimmune disorder.
What is eastern equine encephalitis?
Eastern equine encephalitis is a rare but serious viral infection that is transmitted to humans by the bite of infected mosquitoes.
What is Japanese encephalitis?
Japanese encephalitis is a viral infection that is spread by mosquitoes in Asia and the Western Pacific.
What is Venezuelan equine encephalitis?
Venezuelan equine encephalitis is a viral infection that is transmitted to humans by infected mosquitoes and can cause severe illness.
What is NMDA encephalitis?
NMDA encephalitis is a type of autoimmune encephalitis that is caused by antibodies attacking the NMDA receptors in the brain.
What are the symptoms of autoimmune encephalitis?
Symptoms of autoimmune encephalitis can include memory loss, hallucinations, seizures, and personality changes.
What is the treatment for encephalitis?
Treatment for encephalitis may involve antiviral or antibiotic medications, corticosteroids, and supportive care to manage symptoms.
Can encephalitis be fatal?
Yes, encephalitis can be a serious condition and may be fatal in severe cases.
Is encephalitis contagious?
Encephalitis itself is not contagious, but the viruses or bacteria that can cause it may be.
Can encephalitis be prevented?
Some types of encephalitis can be prevented with vaccines, and avoiding exposure to mosquitoes and other vectors can also reduce the risk of infection.
What is the mortality rate for encephalitis?
The mortality rate for encephalitis varies depending on the cause, severity, and individual factors, but can range from less than 1% to more than 30% in some cases.
How is encephalitis diagnosed?
Encephalitis is typically diagnosed with a combination of physical exams, medical history, laboratory tests, and sometimes brain imaging.
Can encephalitis cause long-term complications?
Yes, encephalitis can sometimes lead to long-term complications such as cognitive or motor deficits, seizures, or behavioral changes.
What are some risk factors for encephalitis?
Some risk factors for encephalitis include a weakened immune system, age (very young or very old), traveling to areas with high rates of encephalitis, and certain occupations (such as working with animals that may carry the virus).
How common is encephalitis?
The incidence of encephalitis varies by region and cause, but is estimated to be around 7 cases per 100,000 people annually in the United States.
What is the most common cause of encephalitis in the United States?

What is the difference between meningitis and encephalitis?
Meningitis is inflammation of the membranes surrounding the brain and spinal cord, while encephalitis is inflammation of the brain tissue itself.
Can pets get encephalitis?
Yes, pets can get encephalitis from some of the same viruses and bacteria that can infect humans.
What is the incubation period for encephalitis?
The incubation period for encephalitis varies depending on the cause, but can range from a few days to a few weeks after exposure to the virus or bacteria.
How is autoimmune encephalitis treated?
Treatment for autoimmune encephalitis usually involves immunosuppressive medications to reduce the immune system's attack on the brain, as well as supportive care to manage symptoms.
What is the prognosis for encephalitis?
The prognosis for encephalitis depends on many factors, including the cause and severity of the infection, the age and general health of the patient, and the availability and effectiveness of treatment.
What is the difference between western equine encephalitis and eastern equine encephalitis?
Western equine encephalitis and eastern equine encephalitis are both viral infections that are transmitted by mosquitoes, but they are caused by different types of viruses.
Can encephalitis be sexually transmitted?
No, encephalitis is not a sexually transmitted infection.
What is the difference between bacterial and viral encephalitis?
Bacterial encephalitis is caused by bacteria, while viral encephalitis is caused by viruses.
What is the difference between arboviral and non-arboviral encephalitis?
Arboviral encephalitis is transmitted by arthropod vectors (such as mosquitoes or ticks), while non-arboviral encephalitis can be caused by other means, such as bacterial infection or autoimmune disorder.
Is encephalitis curable?
Encephalitis may be curable or treatable depending on the cause and severity of the infection.
Can encephalitis be recurrent?
Yes, some types of encephalitis can recur or have chronic symptoms that may require ongoing management.
What is subacute sclerosing panencephalitis?
Subacute sclerosing panencephalitis is a rare but serious complication of measles infection that can lead to progressive brain damage.
