## NATIONALPROGRAMME FOR ENCEPHALITIS CONTROL

## 3257: DR. SHASHI THAROOR :

Will the Minister of HEALTH AND FAMILY WELFARE be pleased to state:

- (a) whether the Government has data on the number of recorded Encephalitis cases in the country during the last five years and if so, the details thereof, year-wise;
- (b) whether it is true that one of the most significant hurdles to tackle the encephalitis burden in the country is the lack of a unified reporting system;
- (c) if so, the details thereof and, if not, the reasons therefor; and
- (d) whether the Government is planning to create a dedicated encephalitis prevention and control programme, separate from the existing vector-borne disease framework, which is likely to eventually decrease the disease burden in the country and if so, the details thereof?

## ANSWER THE MINISTER OF STATE IN THE MINISTRY OF HEALTH AND FAMILY WELFARE (SMT. ANUPRIYAPATEL)

- (a) The National Centre for Vector Borne Diseases Control (NCVBDC) under the Ministry of Health and Family Welfare maintains surveillance data on Japanese Encephalitis (JE) cases, As reported by respective States/UTs, the year-wise number of JE cases reported in the country over the last five years is given at Annexure-I . As per IDSP-IHIP Portal, State/UTs- wise details of Acute Encephalitis Syndrome (AES) data reported, during last 5 years is at Annexure-II
- (b) and (c) While multiple factors contribute to the encephalitis burden in India including environmental, socio-economic, and nutritional and others, it is acknowledged that timely and
- standardized disease reporting plays a critical role in effective surveillance and response. To address this need, the Ministry of Health and Family Welfare, Government of India, has

strengthened its disease surveillance architecture. Integrated Disease Surveillance Program (IDSP) is an important program under National Health Mission that does the disease surveillance in the country. IDSP is implemented in all 36 States/UTs. The program is responsible for the surveillance of epidemic prone diseases including Acute Encephalitis Syndrome (AES) and Japanese Encephalitis (JE). It facilitates early detection and timely response to outbreaks. Under IDSP, weekly reporting from districts is carried out through a three-tier system (S, P, and L forms), capturing suspected cases and laboratory-confirmed cases of AES/JE.

Further, to strengthen the disease surveillance in the country, the Integrated Disease Surveillance Programme (IDSP) has shifted from a paper-based weekly reporting to a paperless reporting through Integrated Health Information Platform (IHIP). IHIP is an information platform that integrates data from various 'registries' to provide near real-time information on health surveillance from all across India for decision-makers to take appropriate public health action. IHIP allows case-based surveillance with geo-tagging, decision support tools, and integrated dashboards. AES/JE is being tracked on IHIP, which offers improved granularity and data visualization to support focused public health actions.

(d) NCVBDC has a dedicated Japanese Encephalitis (JE) control programme named, as National Programme for Prevention and Control of Japanese Encephalitis (JE).
