## 'SPREAD OF DENGUE'

## 309: SHRI MANICKAM TAGORE B. :

Will the Minister of Health and Family Welfare b e pleased to state:

(a) whether it is a fact that the infection geography of Dengue which was restricted to 8 States in 2001, currently covers all the States/UTs in the country and if so, the details thereof, State/UT-wise;

(b) whether it is a fact the shortage of entomologists, a trickier vector, increased travel, and less than optimal public participation in prevention were the causes of the spread of dengue across the country and if so, the details thereof;

(c) whether the Indian Council of Medical Research (ICMR) has been looking at increasing the awareness and promoting prevention, people participation, and use of the latest technology including satellite imaging and drones to map vulnerable areas; and

(d) if so, the details thereof?

## ANSWER THE MINISTER OFSTATE FOR MINISTRY OFHEALTH AND FAMILY WELFARE (PROF. S.P. SINGH BAGHEL)

(a) After a major outbreak of Dengue in 1996, it has spread to newer geography. Currently, Dengue cases are reported from all the States and Union Territories except Ladakh. A statement showing year-wise number of States/UTs reporting Dengue cases since 1996 till 2022 is at AnnexureI and the State/UT-wise Dengue cases in the Country during the year 2022 is at Annexure -II.

(b) Dengue cases are increasing due to many man-made and ecological factors. Shortage of Entomologists is an important factor; therefore, Government of India provisioned budget for contractual Entomologists for the States under NHM. Aedes mosquito, the vector of Dengue breeds in containers, rests in dark places, bites during daytime, transovarian transmission of virus from infected female mosquito to next generation through eggs and ability of eggs to survive in dry conditions for more than one year makes the vector a trickier one to control. Increased travel also helps in introduction of virus and vector mosquito in the newer areas. Public participation is very important in preventing Dengue vector mosquito breeding in and around the houses and to reduce the risk of transmission by adoption of personal protection measures.

(c) and (d) National Center for Vector Borne Diseases Control (NCVBDC), States, Union Territories and Indian Council of Medical Research (ICMR) carry out various awareness activities to promote people participation in prevention of Dengue. ICMR has introduced latest technologies like use of Remote Sensing, Geographical Information Systems, Drones and integrated with Artificial Intelligence (AI) to facilitate the risk mapping of vulnerable areas.
