Epidemic encephalitis What is the disease?

Epidemic encephalitis, referred to as Japanese encephalitis, also known as Japanese encephalitis, is an acute infectious disease of the central nervous system caused by mosquitoes caused by Japanese encephalitis virus.

Epidemic encephalitis What is the disease?

Most people are infected with the virus, and there are no obvious symptoms, or only fever. Less than 1% of people have an obvious inflammatory disease of the brain parenchyma after infection. When neurological symptoms (such as limb numbness, paralysis, etc.) occur, it usually means that the condition is very serious, and the mortality rate is high. Patients who can survive often leave sequelae.

The disease can be prevented by vaccination with Japanese encephalitis vaccine and anti-mosquito measures.

What is the performance of epidemic encephalitis?
The incubation period is 4 to 21 days, usually 10 to 14 days, and there may be no symptoms during the incubation period. Patients with typical symptoms may experience four periods after the incubation period: initial, extreme, recovery, and sequelae.
(1) Initial stage: There may be headache, mental fatigue, poor appetite, nausea, vomiting, lethargy, etc., which may be mistaken for upper respiratory tract infection.
(2) Extreme period: symptoms of damage to the brain parenchyma, such as high fever, disturbance of consciousness, convulsions, difficulty breathing, paralysis, etc.
(3) Recovery period: The body temperature gradually decreases, and the symptoms of brain parenchymal damage are getting better and better.
(4) Sequelae: Some patients may have sequelae, such as aphasia (can not speak properly), limb paralysis, mental disorders and dementia, these sequelae may last for life.
