Dengue mosquito outbreaks are expected to increase next week in Caxias do Sul. The statement comes from Environmental Health Surveillance, an agency linked to the Municipal Department of Health (SMS). In three months, the city has almost reached the number of breeding sites identified in 2021, according to ministry data.
The technical director of the sector, Sandra Tonet, explains that every Monday the issues of Aedes aegypti are broadcast in the town. Since the last publication, more mosquito outbreaks have been detected and the result is expected to exceed breeding sites last year. She says the timing is so alarming, that agency teams are taking 30 to 40 samples of the insect daily.
Cruzeiro is the neighborhood with the highest concentrations of Aedes epidemics. There are 46 in all. Since last year, the region has been ahead on this indicator. According to Sandra, most of the breeding sites come from containers intended to collect rainwater. This is not only observed in Cruzeiro, but also in other places. She reports that 12 collectors were found in a residence and, in all, eight had mosquito outbreaks. It is feared that the high number of registrations could lead to an outbreak of dengue fever in the commune.
The drought means that residences have this large number of rainwater collectors, since the population needs to ration the resource and often suffers without it. This is what environmental health monitoring shows when visiting some homes. Sandra says she understands the situation, but you have to take a few precautions to avoid the proliferation of dengue fever, such as protecting the pools, placing screens, covering them and not letting water stagnate for a week.
Currently, Caxias has 203 outbreaks of Aedes aegypti compared to 209 breeding sites identified in 2021. The city has already reached 97% of the total discovered last year, distributed in 28 districts.
