The National Vector Borne Disease Control Programme (NVBDCP) is a comprehensive public health initiative in India focused on the prevention and control of vector-borne diseases. Community health nurses play a crucial role in the implementation of this program, serving as the bridge between health systems and communities affected by these diseases.
What are Vector-Borne Diseases? Vector-borne diseases are illnesses caused by pathogens transmitted through the bite of infected arthropod species, such as mosquitoes, ticks, flies, and fleas. These vectors can spread serious diseases that affect human health and development.
The NVBDCP operates as an umbrella program that integrates previously separate disease control initiatives. The program targets six major vector-borne diseases that are of significant public health importance in India:
- Malaria
- Lymphatic Filariasis (Elephantiasis)
- Dengue
- Chikungunya
- Japanese Encephalitis (JE)
- Kala-azar (Visceral Leishmaniasis)
Of these diseases, three are targeted for elimination: Malaria, Lymphatic Filariasis, and Kala-azar. The others are considered outbreak-prone and climate-sensitive, requiring ongoing surveillance and control measures.
2. NVBDCP Programme Structure
The NVBDCP functions as a multi-level, integrated administrative and technical framework designed to deliver effective vector-borne disease control interventions across the country. Understanding this structure is essential for community health nurses who work within this framework.

| National | Directorate of NVBDCP (Under Ministry of Health & Family Welfare) | Policy formulation, technical guidance, coordination, monitoring and evaluation, training materials development, program financing |
| State | State Vector Borne Disease Control Division (Under Directorate of Health Services) | State-level program implementation, technical supervision, training, quality assurance, coordination with districts |
| Regional | Regional Offices for Health & Family Welfare (ROH & FW) | Technical support, entomological studies, drug resistance monitoring, quality control, capacity building |
| District | District Malaria/VBD Offices (Under District Chief Medical & Health Offices) | Planning, implementation, monitoring, supervision, and coordination of control activities |
| Sub-district | Primary Health Centers (PHCs), Community Health Centers (CHCs) | Diagnosis, treatment, vector control activities, surveillance, referral services |
| Community | Sub-centers, Fever Treatment Depots (FTDs), Drug Distribution Centers (DDCs) | Case detection, treatment, referral, health education, community mobilization |
| Grassroots | ASHAs, Anganwadi Workers, Community Volunteers | Early case detection, home-based treatment, community education, follow-up, bed net distribution |
Human Resources in NVBDCP
The programme employs various health personnel at different levels:

4. Prevention and Control Strategies
The NVBDCP employs a comprehensive approach to the prevention and control of vector-borne diseases, which can be categorized into three main components:
4.1 Integrated Vector Management
Integrated Vector Management (IVM) is a rational decision-making process for the optimal use of resources for vector control. It aims to reduce or interrupt vector transmission by using the most suitable methods in a cost-effective manner while minimizing negative impacts on ecosystems and non-target organisms.
| Strategy | Methods | Target Vectors | Community Health Nursing Role |
|---|---|---|---|
| Chemical Control |
|
Mosquitoes, sandflies |
|
| Biological Control |
|
Mosquito larvae |
|
| Environmental Management |
|
All vectors |
|
| Personal Protection |
|
All vectors |
|
| Legislative Measures |
|
All vectors |
