Impact of indoor residual spray with synthetic pyrethroid in gandhinagar district, gujarat.
BACKGROUND
Indoor residual spray (IRS), with appropriate insecticide, is an effective weapon for the control of malaria. Two rounds of indoor residual spray, with synthetic pyrethroid, are given in highly malaria endemic areas. It aims to prevent transmission of malaria by adult vector mosquitoes.


OBJECTIVE
To assess the impact of indoor residual spray in the highly malaria-endemic villages of Kalol taluka in Gandhinagar district.


METHODS
High risk population for malaria, based on last three-year malaria situation.


METHODS
Malaria endemic rural areas in Gandhinagar district where indoor residual spray was undertaken with synthetic pyrethroid in 2006 and 2007.


METHODS
Exploratory - Rural areas; Outcome - coverage, acceptance.


METHODS
Percentage and proportions.


RESULTS
Prior to the introduction of synthetic pyrethroid, in 2005, the annual parasitic incidence of the sprayed villages was 33.4. It came down to 8.8 in 2006. Continuation of this strategy in the same villages further brought down the annual parasitic incidence to 1.5 in 2007. A similar trend of steady decline was observed in actual numbers of cases and other malariometric indices as well.


CONCLUSIONS
IRS, it still has a major role in the control of malaria if implemented with proper supervision, better coverage and community participation.
