National Institute of Malaria Research
NIMR Field Unit: Raurkela (Odisha)
The field station at Rourkela in Sundargarh district (Orissa) was established in 1988 with the following objectives :
a) Conduct applied field research on malaria.
b) Develop and demonstrate appropriate disease vector control methods.
c) Study socio-economic aspects of malaria with particular reference to sustainability of interventions developed and
d) Facilitate transfer of technology to users.
Rourkela is an industrial city of Sundargarh district in Orissa state and is located in the Garhjat hills of eastern plateau between 20o-12’N and 84o-53’E at an altitude of 200 mt above sea level. The city is well connected by rail and is situated on Howrah-Mumbai railway route of South eastern Railway.
Physiographically the area consists of undulating uplands intersected by forested hills, rocky streams, rivers, springs and paddy fields in the valleys. The area is characterized by a tropical climate and receives high rainfall during Southwest monsoon (June-September) and retreating Northeast monsoon (December-January). Average annual rainfall ranges between 160-200cm. The minimum and maximum temperatures are in the range of 11oC to 44oC with a mean minimum and maximum temperature range of 14.3oC to 39.2oC during coldest and hottest months. Thirty six percent of the geographical area of the district has semi-evergreen or tropical dry deciduous forest. Nearly 62 % of the rural population consists of tribal population represented by 40 ethnic tribal communities.
Local Malaria Problems :
Malaria is a major public health problem in Orissa state, which contribute highest number of malaria cases (22 %), 43% of total P. falciparum cases and about 50% of all reported deaths due to malaria in the country although it constitute only 4% of the total population of India. Tribal areas of the state such as Sundargarh district are the most seriously affected regions of the state where malaria exists in meso- to hyper endemic form. P. falciparum is the major cause of malaria and accounts for 80-90% malaria cases in the tribal areas of the state, which have distinct ecological features such as hilly terrain, forest fringe and forested area or foothill ecosystems where all the malariogenic factors operate at their maximum efficiency. Malaria is clearly one of the major health problem in this region and is responsible for significant morbidity and mortality.
The entire state of Orissa is under the influence of two primary vector species viz., An. culicifacies and An. fluviatilis. The previously recorded An. sundaicus which caused many epidemics in the coastal areas in 1940’s has totally disappeared. Of the two vector species, An. culicifacies is widely prevalent in the plain and coastal area where malaria is less and seasonal, whereas, An. fluviatilis is restricted to the hilly forested or foothill area of the state and is responsible for intense transmission due to high anthropophilic index of this species.
