According to the results of the third cycle of the Indicator Rapid Survey for Aedes aegypti (LIRAa), Macapa is at low risk of infection by Aedes aegypti mosquitoes. Based on the indicated findings, the Municipal Health Surveillance Secretariat (SMVS) began a schedule of inspections, intensifying them in neighborhoods with the highest number of breeding sites for the transmission of dengue, yellow fever, chikungunya and Zika viruses.
Neighborhoods such as Zerão, Fazendinha, Centro and Mara Baixo received procedures consisting of home visits, removal of subjected deposits and focal treatment. In addition, vacant lands, contaminated landfills, open pits, and tires on public roads were identified to be sent to the relevant sectors.
The research was conducted from August 21 to 30. In total, in this third cycle, settlement field agents visited 6,000 homes to collect samples and evaluate potential foci where mosquito larvae could breed.
The survey showed that the largest source of reproduction is concentrated in household waste at a rate of 52%, followed by 27% from tire larvae that are improperly disposed of.
Aedes aegypti is a native mosquito that lives in or around homes. “Mosquitoes transmit diseases such as dengue, chikungunya, yellow fever and Zika virus. Therefore, it is very important to keep objects in which water can accumulate facing downwards, thus reducing the risk of Aedes aegypti outbreaks,” explains the wallet’s owner, Gilmar Dominguez.
In November, SMVS begins the fourth cycle of LIRAa, and agents begin collecting samples from November 6 to November 14.
