The state government evolved a new strategy called ‘Sira’ to curb the mosquito menace in the state. With municipalities failing to implement a proper strategy to check the mosquitoes, the municipal administration department evolved the strategy to be adopted by all municipalities and corporations including the GHMC in the state.

Orders issued to this effect on Monday stated that typically municipal bodies do not follow a systematic approach to control mosquitoes. What they do is more of crisis response to malaria and dengue epidemics. Thus, the government has decided to adopt a strategy called the Surveillance, Information, Response, Analysis (SIRA) model to control mosquitoes at the breeding stage.

Surveillance: Anti-larval operation (ALO) teams - each team consisting of one field assistant and two field workers will be deployed. All households to be covered weekly to identify domestic and peri-domestic breeding places and to carry out chemical treatment using appropriate larvicide in all breeding sources detected to be positive.

All open breeding sources like tanks, rivers, storm water drains, and open drains are to be identified and treated weekly by the ALO team which is recorded through wall stencils and survey registers. Temporary water stagnation points, construction sites and roof tops have to be identified, especially during the monsoons.

Information: Heads of circle, or a smaller geographical unit, will convene meetings every evening with the health officers, assistant entomologist, deputy project officers and veterinary officers to review the work of anti-larval operation teams and special teams, including larval density and adult density analysis. Progress reports will be submitted to the commissioners, chief entomologist, chief medical and health officer.

Response: After identification of the hotspots, analysis of citizens’ complaints, press reports and case reports, action would be taken up. This includes pig catching and segregation done by veterinary wing in hotspot on the same day. Outreach programme would then be taken up by the community development officer and slum development officers. Special attention will be given to recurrent cases in slums. Anti-larval operations, thermal fogging with portable and vehicle mounted fogging machines, space spray with power sprayers as and when mosquito transmitted cases are reported will be taken up. Indoor residual spraying would also be carried out in and around areas of reported cases.

Analysis: Commissioners will analyse the incidence of mosquito-borne diseases and entomological parameters, weekly. Entomological teams would monitor and evaluate mosquito densities, weekly. Each team will study the larval and adult mosquito densities at 10 fixed and 10 random locations and provide feedback to ALO teams. Senior officers will regularly visit the areas and explain people about the anti-mosquito campaign.


■ Reduction in the

incidence of malaria, dengue cases.

■ Substantial reduction in the larval density and mosquito density.

■ Reduction of complaints by public, leaders, media.
