Executive Summary:
Filariasis is one of the major public health
problems in India next only to Malaria and has
got social, economic and physical hazards. Filariasis
commonly known as elephantiasis, leads to permanent
swelling of the legs and of certain other parts
of the body besides causing requiring attacks
of fever and inflammation of the lymphatic system.
Filariasis is a major public health hazards to
which almost 40% of the Indian population is exposed.
Filariasis leads to irreversible chronic manifestations
which are responsible for social stigma besides
causing considerable economic loss and severe
physical disability to the affected individuals.
The Office of the Entomologist cum Research Officer
(Filaria), NFCP Guwahati Unit is the only Office
of the state, functioning larvicidal, entomological
activities as well as parasitological survey in
Guwahati City.
Mosquitoes (Culex quinquifasciatus, Mansonia annulifera
etc.) are the vectors for the transmission of
filariasis from man to man.
Background:
National Filaria Control Programme (NFCP)
was launched in India in1955 for the control
of bancroftian Filariasis for the following objectives:
1. Delimitation Survey in known endemic areas
2. Large scale control measures in selected areas
and
3. Training of personnel required to man the programme.
The NFCP, Assam Unit was started at Jorhat in
1958 as the Office of the Entomologist cum
Research Officer (Filaria). In June 1964 this
NFCP Unit/Office had been shifted from Jorhat
to Guwahati as NFCP, Guwahati Unit. The Entomologist
cum Research Officer (Filaria) is the head / incharge
and DDO of this NFCP, Guwahati Unit.
Process of Plan Preparation:
The Entomologist cum Research Officer (Filaria),
NFCP Guwahati Unit presently covers 3,10,000 populations
in Guwahati Metro. Following process of plan preparation
may be worked out -
1. Entomological Survey especially collection,
identification and dissection of mosquitoes/vector
mosquitoes in Guwahati Metro.
2. Night Blood Slide Collection Survey for the
detection of Micro filaria (Mf) carrier in the
community.
3. Larvicidal Spraying operation in weekly interval
for the control of mosquitoes/vector mosquitoes
4. Environmental engineering through source reduction
and water management.
5. Biological control through larvivorous fishes
6. Information Education and Communication to
generate community awareness
7. Home based Morbidity management to the Filaria
patient
8. Biolarvicidal spraying operation may be initiated
in Guwahati Metro
Situation Analysis:
The Office of the Entomologist cum Research Officer
(Filaria), NFCP Guwahati Unit has been covering
3,10,000 population. As per NVBDCP census 2007
the population of Guwahati metro was 9,83,148
. Within limited manpower of the NFCP Unit, to
cover the entire population in Guwahati metro
is impractical. Therefore additional manpower
is required for the smooth functioning of this
Filaria Control Programme in the metro to cover
the entire population.
