Japanese Encephalitis: A Brief Review on Indian Perspectives.

Area of Science:

• Medical Entomology
• Virology
• Public Health

Background:

• Japanese encephalitis (JE) is a significant public health concern in Asia, characterized by expanding geographical distribution.
• It is a vector-borne viral disease caused by the Japanese encephalitis virus (JEV), a Flaviviridae family member.
• JE is a leading cause of acute encephalitis syndrome, resulting in substantial morbidity, mortality, and disability globally, with approximately 68,000 clinical cases annually.

Purpose of the Study:

• To review recent advancements in the diagnosis of Japanese encephalitis.
• To highlight challenges and progress in prophylactic interventions for JE control.
• To discuss effective strategies for managing this notifiable disease.

Main Methods:

• Literature review of recent studies on Japanese encephalitis.
• Analysis of diagnostic techniques and prophylactic measures.
• Evaluation of disease control strategies, including vaccination and vector control.

Main Results:

• Japanese encephalitis is increasingly recognized as a notifiable disease in India, necessitating enhanced surveillance and management.
• Vaccination is identified as the most effective tool for controlling JE, alongside supportive care for patients in the absence of antivirals.
• Vector control is resource-intensive, underscoring the importance of vaccination strategies.

Conclusions:

• Effective control of Japanese encephalitis relies on robust vaccination programs for both animals and humans.
• Addressing challenges in diagnosis and implementing advanced prophylactic interventions are crucial for mitigating JE's impact.
• Continued research and public health efforts are essential to combat the expanding threat of JE.
