Environmental study
During the researchers’ visit, it was observed that water
accumulated in drums, drains, ponds and other containers
of water. The inhabitants used to take tea in plastic and
earthen pots and throw these used pots away in their yards.
Water accumulated in these containers, after rain. Water also
accumulated in broken flower vases, earthen pots, coconut
shells and tyres, which favoured mosquito breeding. After
careful examination, these coconut shells, tyres, earthen pots,
flower tubs and plastic containers were found to be positive
for Aedes aegypti larvae. There was no scarcity of water inthe villages, but water for cattle was collected and stored in
earthen pots without a cover. Mosquitoes were found to be
breeding there. The relative humidity and temperature of the
district was 75–90% and 27–37 °C respectively, in the month
of September. The total rainfall in the district during September
2012 was 302 mm.13
