Acute Encephalitis Syndrome (JE-AES)


    In News

    Recently, the Prime Minister has emphasised providing clean tap water on priority to every household in Acute Encephalitis Syndrome (JE-AES) affected areas under Jal Jeevan Mission.


    • The districts of Assam, Bihar, Tamil Nadu, Uttar Pradesh and West Bengal are on the high priority. 
    • Jal Jeevan Mission has significantly strengthened the preventive measures to reduce the spread of JE-AES by providing a clean tap water supply to economically poor households in these states.
      • Jal Jeevan Mission was launched in 2019, with an aim to provide drinking water connections to all rural households by 2024.
      • About 17 percent of the households in India had a functional tap water connection but the number was as low as 8 per cent in these aspirational districts.
    • Specific funds for JE-AES affected priority districts are allocated on the basis of drinking water sources and the extent of water contamination.

    • Govt. of India, as part of the National Programme for Prevention & Control of JE/AES, follows a multi-pronged strategy encompassing
      • Preventive (sanitation, safe drinking water, improvement in nutrition etc.)
      • Case management (capacity building of medical and para-medical staff referral etc.).
      • Rehabilitation (physical and social rehabilitation of disabled children).
    • 2 doses of JE vaccine have been approved to be included in UIP to be given one along with measles at the age of 9 months and the second with DPT booster at the age of 16-24 months w.e.f. April, 2013.

    Way Forward

    • Improve nutritional status of children at risk of JE/AES.
