Programmes under NVBDCP
Various programmes under NVBDCP ar
1.Kala Azar control programme: Kala-azar or visceral leishmaniasis (VL) is a chronic disease caused by an intracellular protozoan (Leishmania species) and transmitted to man by the bite of female phlebotomus sand fly. Currently, it is the main problem in Bihar, Jharkhand, West Bengal and some parts of Uttar Pradesh.
- It is a centrally sponsored programme in endemic states in 1990-91. A tripartite MoU has been signed between India, Bangladesh and Nepal for achieving Kala Azar from the South East Asia Region.
- All programmes are being implemented by the NVBDCP.
- It has a target of reducing the annual incidence of Kala Azar to less than one per 10000 population at the block PHC level.
2. National Filaria Control Programme: Bancroftian filariasis caused by Wuchereria bancrofti, which is transmitted to man by the bites of infected mosquitoes – Culex, Anopheles, Mansonia and Aedes. Lymphatic filaria is prevalent in 18 states and union territories. Bancroftian filariasis is widely distributed while brugian filariasis caused by Brugia malayi is restricted to 6 states – UP, Bihar, Andhra Pradesh, Orissa, Tamil Nadu, Kerala, and Gujarat.
- The National Filaria Control Programme was launched in 1955. It has the objective of controlling Lymphatic Filariasis in un-surveyed areas and urban areas through anti-parasitic and anti larval measures.
- The National Health Policy 2017 envisages the elimination of Lymphatic Filariasis. 2020 was the target year for Global elimination of the disease.
