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

(a): Although across the country, the total number of cases of Dengue & Chikungunya has decreased in 2025 (till June) as compared to corresponding period in 2024 but cases marginally increased in some of the States/UTs.

Cases of other vector-borne diseases like Malaria (till May) and Kala-Azar (till June) marginally increased in some of the States/UTs due to enhanced surveillance & paperless reporting on Integrated Health Information Platform(IHIP) in 2025 as compared to corresponding period in 2024. Notably, there is no increase in number of Japanese Encephalitis cases in 2025 (till June) as compared to corresponding period in 2024.

State/UT wise details of number of Vector Borne disease cases is attached at Annexure-1.

- (b) State-wise details of number of dengue cases and related deaths reported during the last three months (April-June, 2025) are attached at Annexure-2.
- (c) & (d): The National Center for Vector Borne Diseases Control (NCVBDC) under the Ministry of Health and Family Welfare administers an umbrella programme, namely, National Vector Borne

The Ministry of Health and Family Welfare, Directorate General of Health Services and National Center for Vector Borne Diseases Control (NCVBDC) are regularly monitoring the surge of Vector Borne Diseases in the country through regular reviews and reports submitted by the States/UTs and through field visits.

As the risk of Vector Borne Diseases increases during monsoon and post monsoon period, Government of India (GoI) starts preparatory activities well before the monsoon season and following preventive & containment measures are being undertaken to prevent and control the surge in cases of Vector Borne Diseases in the Country, especially in high-incidence urban areas:

-  Disease Management involving early case detection with active, passive and sentinel surveillance followed by complete and effective treatment, strengthening of referral services, epidemic preparedness and rapid response.
-  Regular Monitoring & Supervision, Supportive Interventions aiming at Behaviour Change Communication, Inter-Sectoral Convergence including high-level advocacy with allied ministries, Human Resource Development through capacity building and policy development.
-  Integrated Vector Management including Indoor Residual Spray in selected high-risk areas, Long Lasting Insecticidal Nets in high malaria endemic areas, use of larvivorous fish, antilarval measures in urban areas including bio-larvicides and minor environmental engineering and source reduction for prevention of breeding.
-  For real time monitoring, States/UTs have been trained to enter the data on Integrated Health Information Portal - Vector Borne Diseases (IHIP-VBD) portal.
-  For early diagnosis and complete treatment of VBDs, drugs and diagnostics are supplied to the States/UTs.
-  Annual Mass Drug Administration in mission mode for Lymphatic Filariasis and Morbidity Management and Disability Prevention kit distribution for rehabilitative and self-care services for the lymphedema cases.
-  Indigenous Japanese Encephalitis vaccines have been introduced for routine immunization in endemic areas.
-  Secretary, Ministry of Health and Family Welfare and Secretary, Ministry of Housing and Urban Affairs,jointly reviewed Dengue situation and preparedness in major municipal corporations from nine States in Inter-ministerial meeting held on 2nd July, 2025.

(e) In order to tackle any outbreaks and to prevent further spread, the Government ensures adequate stocks of diagnostic kits and drugs across the country. Further, Under National Health Mission, adequate budgetary support is being provided to all States/UTs under the annual Program Implementation Plan to tackle the outbreak and prevent further spread.
