National Vector Borne Disease Control Programme




Malaria is one of the major public health problems of Assam since before independence. Assam is contributing more than 5% of the total malaria cases of the country. The excessive rainfall, prolonged rainy season, recurrent waves of flood in a year, forest fringes, hilly terrain and conductive climatic condition create a vector friendly environment.

It is estimated that 11630158 nos. populations are living under malaria high risk area. Among them 15147 nos. village, 2144 sub-centers and 122 PHC are identified as a malaria high risk.

Strategies for Malaria Control

As per National Vector Borne Disease Control Programme following are the strategies of malaria control programme.

1. Early Detection and Complete Treatment
2. Vector Control
4. Human Resource Development
5. Public private partnership

Early Detection and Complete Treatment - It includes surveillance of fever cases by active and passive agencies. The Blood samples of fever cases are to be collected by workers and in the micro slides for examination under microscope. The Rapid Diagnostic Kits (Pf) are also a tool of malaria diagnosis. The diagnosed malaria cases are to be treated by the trained health worker and medical Officers according to the guidelines for National Vector Borne Disease Control Programme. For the improvement of early diagnosis & complete treatment following action are to be initiated and reflected in the action plan.

 Vector Control

DDT 50% is recommended in the state for indoor spraying at malaria prone areas. The Annual Parasite Incidence (API) is the criteria for selection of malaria prone areas for spraying operation. Accordingly details operational plan is furnished below considering API above 3 as per GIS data of the district.

Supervision & Monitoring Plan of DDT Spray Operation

1.     Consecutive supervision by MPW (M)

2.     Concurrent supervision by Medical Officers/District Malaria Officers/ Joint DHS (district)/ Officers from State Head Quarter.

3.     Wages of spray workers will be release after getting completion certificate from PRI.

Personal Protection

The uses of mosquito net by the people are also an important strategy for prevention of malaria. The mosquito nets are to be impregnated with a insecticide (Deltamethrine). Because the malaria mosquito bite the people at night. The community of the state preferred the uses of mosquito net.

Larvivorous Fish

Introduction of Larvivorous fish in the state as a vector control measure will be initiated from 2008. The considering the hilly terrain and landscape of the state 4 districts are identified in the first step for culture distribution & monitoring of Larvivorous fish.

The identified districts are Kamrup, Lakhimpur, Hailakandi & Karbi-Anglong.


Out door space spray with Malathion Technique is one of the strategies for control malaria specially when there is high incidence of fever cases in urban and semi-urban areas.

Rapid Response Team (RRT)

Each endemic district will form a RRT for all vector borne diseases comprising the followings.

Behaviour Change Communication (BCC)

BCC is a continuous process and will be carried out throughout the year. More stress will be given during transmission season and during immunization campaign.

Inter personal communication through ASHA / AWW / ANM
Focal Group Discussions in endemic villages.


The Tea Estates and PSU like Coal India , ONGC , OIL are involved in vector control measures, such as in fogging operation . PRI, NGO SHG are also involved in ITBN programmes.
Some private hospitals are sending reports to the state on JE.
IMA holds workshop on JE case management in Collaboration with State VBDCP, Assam.
