INTRODUCTION
DIRECTORATE OF NATIONAL VECTOR
BORNE DISEASE CONTROL PROGRAMME.
COMPOSITION.
FUNCTIONS.
FORMATION OF STRATEGIES.

3. Dr Raghuram V 3
STRATEGIES INCLUDE
• Enhanced surveillance with support of community
based volunteers and grass root level workers
• Early diagnosis and proper case management through
through strengthning primary and secondary health
institution
• Integrated vector management using bio-friendly
method and limiting use of insectisides
• Epidemic preparednesss and rapid response
• Behaviour change communication
• Computerised management information system
• Intersectoral collaboration

MALARIA
•MAGNITUDE OF PROBLEM
Provisional data for the year
2004 reveals
largest number of were reported in Orissa
followed by Gujarat , chattisgarh , WB ,
Jharkhand , and karnataka
•1.87 million cases of malaria which includes
0.86 million cases of falciparum
malaria and 1006 death were reported
in 2003.

MALARIA CONTROL PROGRAMMES
 -National malaria control programme
# launched in 1953
# It was based on indoor residual
spraying with DDT twice a year
in endemic areas.
 -National malaria education programme
# launched in 1958
# divided into preparatory ,attack ,
consolidation and maintenance phases.

MODIFIED PLAN OF OPERATION
1.Objectives
2.Reclassification of endemic areas
3.Areas with API more than 2
-Spraying
-entomological assesement
-Surveillance
-Treatment of cases

8. Dr Raghuram V 8
4.Areas with API less than 2
-Spraying
-Surveillance
-Treatment
-Follow up
5.Drug distribution centres and fever
treatment depots.

9. Dr Raghuram V 9
6.Urban malaria scheme
7.P.falciparum containment
8.Research
9.Health education
10.Reorganization

10. Dr Raghuram V 10
SURVEILLANCE
1.Active surveillance
This is carried out by paid workers
called “surveillance workers”.
2.Passive surveillance
This is carried out by local health
agencies like PHC , sub centres ,etc

11. Dr Raghuram V 11
MALARIA CONTROL THROUGH
PRIMARY HEALTH CARE
-New approach to malaria control was approved
by WHO in 1978 i.e implementation of malaria
control in context of the primary health care
strategy.
-In 1999 Govt of india introduced “National
anti malaria programme”
-Components include
# early case detection and treatment

12. Dr Raghuram V 12
# selective vector control and personal
protection methods.
# epidemic planning and rapid response
# intersectoral coordination
# use of larvivorous fish

KALA-AZAR
 Kala-azar is slow progressive indegenous
disease caused by protozoan parasite
of genus LEISHMANIA.
 In india leishmania donovani is the only
parasite causing this diaease.
 Vector of this disease is SAND FLY.
(PHLEBOTOMUS AREGENTIPUS)

14. Dr Raghuram V 14
 EXTENT OF KALA-AZAR
Endemic in eastern states of India namely
Bihar , Jharkhand , UP and West Bengal.
48 districts endemic ,sporadic cases
reported from few districts.
Estimated 165.4 million population at risk
in 4 states

CONTROL EFFORTS IN INDIA
•Organised centrally sponsored programme
launched in endemic areas in 1990-91
•PROGRAMME STRATEGY INCLUDES
-Vector control through spray of DDT
up to 6 feet height from the ground twice
annually.
-Early diagnosis and complete treatment
-Information education communication.
-Capacity building.

17. Dr Raghuram V 17
•ACHIEVEMENT
By 2003 compared to 1992 there is
76.38% decline in incidence and 85.20%
decline in death.

18. Dr Raghuram V 18
KALA-AZAR ELIMINATION
INITIATIVE
•It includes elimination of kala-azar to 100%
by the year 2010.
•In addition to kala-azar medicines & insect
-sides , cash assistance is being provided
to endemic state since dec 2003 to facilitate
effective strategy implementation by states
