After many years of implementing the expanded Japanese encephalitis vaccination program, the number of cases has decreased rapidly, but the risk still exists for young children. Parents need to take their children to get the first dose of the Japanese encephalitis vaccine at the right time and ensure that the number of doses is complete according to the vaccination schedule recommended by the Ministry of Health.

Japanese encephalitis is a common disease in children under 15 years old, which can cause death very quickly within the first 7 days due to damage to the central nervous system. Even though Japanese encephalitis is treated, the risk of sequelae and complications is still very high.

Japanese encephalitis is a dangerous disease that can occur at any age, but is most common in children under 15 years old. If the patient is not detected early and treated promptly, it will likely lead to death.

Symptoms of Japanese encephalitis in children are often difficult to recognize, mainly vomiting, crying, and stiffness. The cause of the disease is mostly due to mosquitoes biting sick livestock and poultry and then transmitting the virus to the patient.

Summer, especially from May to August, is the peak season for Japanese encephalitis in children. The pathogen often directly attacks the brain parenchyma, with a mortality rate of 10-15%, and 35-45% leaving neurological and motor sequelae.
