On Monday (16/1) the rapid indicator survey for Aedes aegypti (LIRAa) started in Bavirama. Used as a means of rapidly controlling, by sampling, the number of properties with enclosures containing Aedes aegypti larvae, the aim of LIRAa is to identify areas of the city with the highest incidence/infestation of mosquitoes and the predominant breeding sites.
The Bavirama Department of Health requires citizens to receive endemic agents in their homes so that they can conduct research for larval vector infestations and collect samples. Visits take place through January 20, Friday.
How it works
In inspections, customers look for pockets of the Aedes aegypti mosquito in places and objects where water can accumulate. Then, this data is analyzed in the laboratory and tabulated, so that the Building Vector Infection Index (IIVP) can be calculated. With LIRAa, it is also possible to identify the most common mosquito breeding sites, as well as the areas and neighborhoods with the highest prevalence.
The State Center for Health Surveillance (Cevs) issued a risk statement at the end of 2022 due to the increase in the number of dengue cases recorded in Rio Grande do Sul. In one year, notifications have increased nearly 5.5 times, confirmed cases, 6.3 times and deaths, six times.
In the municipality of Bavirama, in 2021 there was a positive case of dengue fever, a number that rose to five in 2022. The Ministry of Health warns the population that there may be another increase in cases in 2023.
