What does Japanese encephalitis look like?

Japanese encephalitis (JE) is an infection of the brain caused by the Japanese encephalitis virus (JEV).

Japanese encephalitis
Specialty Infectious disease
Symptoms Headache, fever, vomiting, confusion, seizures
Usual onset 5 to 15 days after infection
Causes Japanese encephalitis virus (spread by mosquitoes)

How is Japanese encephalitis diagnosed?

Laboratory diagnosis of JE is generally accomplished by testing of serum or cerebrospinal fluid (CSF) to detect virus-specific IgM antibodies. JE virus IgM antibodies are usually detectable 3 to 8 days after onset of illness and persist for 30 to 90 days, but longer persistence has been documented.

How does the Japanese encephalitis affect your body?

JE kills up to 30 percent of those who develop the disease, mostly children. Among survivors, half are left with permanent brain damage, such as paralysis, seizures, inability to speak, memory loss, impaired cognition, and other mental disorders.

Can you recover from Japanese encephalitis?

There’s currently no cure for Japanese encephalitis. Treatment involves supporting the functions of the body as it tries to fight off the infection. The person usually needs to be admitted to hospital so they can be given fluids, oxygen and medication to treat any symptoms.

What happens if you get Japanese encephalitis?

In people who develop severe disease, initial symptoms include fever, chills, headache, fatigue, nausea and vomiting. The disease can progress to inflammation of the brain (encephalitis) and is often accompanied by seizures. Coma and paralysis occur in some cases.

What are the means and symptoms of Japanese encephalitis?

What is the incubation period for Japanese encephalitis?

Most people infected with JE do not have symptoms or have only mild symptoms. However, a small percentage of infected people develop inflammation of the brain (encephalitis), with symptoms including sudden onset of headache, high fever, disorientation, coma, tremors and convulsions.

Which of these is the cost for Japanese encephalitis?

Less than 1% of people infected with Japanese encephalitis (JE) virus develop clinical illness. In persons who develop symptoms, the incubation period (time from infection until illness) is typically 5-15 days. Initial symptoms often include fever, headache, and vomiting.

Do you need a booster for Japanese encephalitis?

The individual costs for JE vaccination are $292 per dose, with an administration fee of $46. Short-term treatment of JE costs nearly $30,000, and long-term treatment of JE also comes with a large bill of $8,437. These costs are not simply monetary but are also felt in lost economic productivity.

Is Japanese encephalitis infectious?

Both doses of the vaccine should be completed at least 7 days before you visit an area where there’s a risk of Japanese encephalitis. If you continue to be at risk of infection, a booster dose of the vaccine should be given 12 to 24 months after you’re first vaccinated.

Why it is called Japanese encephalitis?

How often do you need Japanese encephalitis?

Japanese encephalitis is a mosquito-borne viral infection. It is the leading cause of viral encephalitis in Asia. Humans can get the disease a mosquito that carries the virus bites them. Japanese encephalitis virus (JEV) cannot transmit from one person to another.

What causes Japanese encephalitis How does it enter the body?

How can Japanese encephalitis be prevented?

Japanese encephalitis virus JEV is the most important cause of viral encephalitis in Asia. It is a mosquito-borne flavivirus, and belongs to the same genus as dengue, yellow fever and West Nile viruses. The first case of Japanese encephalitis viral disease (JE) was documented in 1871 in Japan.

What countries do you need Japanese encephalitis?

IXIARO is given as a two-dose series, with the doses spaced 28 days apart. Adults aged 18–65 years can get the second dose as early as 7 days after the first dose. The last dose should be given at least 1 week before travel.

The virus that causes Japanese encephalitis — a flavivirus — can affect both animals (pigs and birds) and humans. In humans, it can cause inflammation of your brain (encephalitis) and the membranes that cover it. Being bitten by an infected mosquito is the only way of catching this virus.

The best way to prevent Japanese encephalitis virus infection is to protect yourself from mosquito bites. Use insect repellent, wear long-sleeved shirts and pants, treat clothing and gear, and get vaccinated before traveling, if vaccination is recommended for you.
