Suspicious cases, increase in outbreaks and 5 neighborhoods infested in Jaraguá do Sul

During the first 60 days of the year, 257 outbreaks of the Aedes aegypti mosquito were reported in Jaraguá do Sul. Compared to the same period last year, 177 were registered, showing a 45% increase in registered outbreaks.

So far, there are no autochthonous cases (contracted in the commune itself) of dengue fever in the commune. However, there are 11 suspected cases of the disease.

Talita Sevegnani, head of epidemiological surveillance, explains that Aedes aegypti surveillance and control activities are carried out through traps and visits. Currently, 601 traps are monitored weekly. Visits are also made to 190 strategic points, such as tire shops, cemeteries and material recycling points.

“During home visits – to check for possible mosquito outbreaks – agents of endemic diseases still encounter resistance from residents to open the doors of their homes,” Talita laments.

Certain neighborhoods have a higher incidence of mosquito outbreaks and are therefore considered infested. They are: Centro, Vila Baependi, Vila Nova, Nova Brasilia and Vila Lenzi. In addition to these, other neighborhoods follow the same path with a strong circulation of the Aedes aegypti mosquito, as is the case of the Ilha da Figueira neighborhood.

Dengue fever vs mosquito concentration

Dengue fever cases are directly related to the concentration of the mosquito, ie the more mosquitoes there are in circulation, the greater the probability of having people infected with the disease. Therefore, it is important to know the habits of the mosquito in order to fight it as a means of preventing the disease.

Studies show that the best opportunity to confront Aedes is in the aquatic phase (larva and pupa), especially with the removal or sealing of places where the female lays her eggs. As a personal protection mechanism, repellents can be used. And eliminate mosquito breeding sites with the following measures:

  • Adequate water storage;
  • Keep the water tank sealed;
  • Watch out for pet waterers and planters;
  • Be careful with small objects and toys that can accumulate water;
  • Plants, especially bromeliads, in urban areas can also be sources of dengue mosquitoes;
  • Beware of drains and gutters (keep drains clean and screened and avoid standing water)
