Japanese encephalitis
ICD-10 A87.1 is a billable code used to indicate a diagnosis of japanese encephalitis.
Japanese encephalitis (JE) is a viral infection caused by the Japanese encephalitis virus (JEV), primarily transmitted through the bite of infected mosquitoes, particularly in rural agricultural areas of Asia. The disease can lead to severe neurological complications, including encephalitis, which is characterized by inflammation of the brain. Symptoms typically begin with fever, headache, and vomiting, progressing to neurological manifestations such as seizures, altered mental status, and paralysis. The case fatality rate can be as high as 30% in severe cases, with many survivors experiencing long-term neurological sequelae. Vaccination is the most effective preventive measure against JE, especially for individuals traveling to endemic areas or those living in high-risk regions. The vaccine is recommended for children and adults who are at increased risk of exposure. Early diagnosis and supportive care are crucial for improving outcomes in affected individuals. The clinical presentation can vary widely, and not all infected individuals will develop symptoms, making awareness and vaccination critical in endemic areas.
