Next Monday (3), data collection will begin in the field for the Fourth Rapid Index Survey on Aedes aegypti (LIRAa). According to the Center for Zoonoses Disease Control (CCZ), the sample survey will assess larval infestation rates and, primarily, the predominant mosquito container/breeder species, in order to direct control measures to areas of greatest risk within an area. Municipal.
“LIRAa is an activity that allows the identification of areas with the highest prevalence of Aedes aegypti mosquitoes, and thus be able to indicate transmission rates of dengue, Zika virus and chikungunya. With the result, we will identify new strategies for vector control work,” explains the Municipal Vector Control Program Coordinator. (PMCV), Claudimir Barcelos.
Field work will continue until Friday (8). During the week, Endemic Control (ACE) agents will visit 8,190 properties in the 100 neighborhoods that make up the 19 layers. “100 ACEs are involved in this procedure, and they also have field supervisors and staff, as well as laboratory staff. The activity consists of visiting a certain number of properties and collecting caterpillars to identify, and thus determine the Infection Index (IIP) in the municipality, the neighborhoods with the highest risk and prevalent stocks”, added Claudemir.
The previous LIRAa, which was implemented in June, showed a Building Infection Index (IIP) of 2.8% in Campos. This result was lower compared to previous surveys, resulting in 3.9% and 5.4% implementations, respectively, in April and January. This year, 180 cases of dengue, four cases of chikungunya and two cases of Zika virus have been confirmed.
