Smoke is only spread in areas with a high Aedes aegypti infection – GAZ – Notícias de Santa Cruz do Sul e Região

The municipality of Santa Cruz do Sul has developed daily and continuous work to control the Aedes aegypti mosquito in the municipality. Educational activities for the population, clean-up work in nearby areas and the use of biological larval toxins are some of the resources used. However, according to the municipal administration, some people are skeptical about the choice of a particular technology. The Department of Health clarifies, through the Department of Health Surveillance and Operations, that there are technical criteria for the application of Fumacê, Ultra Low Volume (UBV) mode of chemical vector management.

This device is intended for use only in areas where Aedes infection is high and where spread continues and where cases of Dengue, Zica, or Chikungunya have been reported according to protocols of the Ministry of Health forwarded by the 13th Regional Health Coordination (CRS). ) and Centro State Health Surveillance (Cevs). In other words, cases of dengue fever continue to occur in the area, even after mechanical control measures (elimination of nesting sites) and control of biological larval toxins.

In larger areas, the smoke is dispensed with a mini-aerosol generator on a pallet truck. In smaller or hard-to-reach areas, a motorized backpack bulldozer is used. Applications will always take into account the analysis of entomological and epidemiological data (number of cases, date of symptoms, number of breeding sites and measures taken). According to the guidelines of the National Dengue Control Program, the mechanical control of Aedes aegypt – manual elimination of nesting sites – is the most effective way to eliminate individuals from vector populations. Elimination of nesting sites is preventive and should be done regularly throughout the year.

Chemical control with larval toxins is recommended as a complementary vector control agent and is used only in breeding sites that cannot be eliminated. Insecticides should only be used locally to prevent epidemics and in controlled areas at strategic points to avoid side effects on the environment. The municipal authority also points out that 80% of the breeding grounds for Aedes aegypt are in homes and other private environments, which makes community involvement necessary for the control and control of mosquitoes. In addition, an insect may develop resistance to the venom if the insecticide is used arbitrarily.

In this regard, the Ministry of Health urges the population of Santa Cruz to assist in measures to prevent the spread of mosquitoes by taking a number of measures. See what they are:

  • Use a body repellent, especially for people with dengue or zika fever. This prevents uninfected mosquitoes from getting infected by biting the sick. Aedes attacks primarily during the day and is silent;
  • Wear long-sleeved pants and blouses;
  • If possible, install window and door screens;
  • Use aerosol insecticides indoors. Spread under the beds, on the tables, behind the furniture, near the tank, shake the curtains;
  • Always put rubbish in sealed bags;
  • Pierce the cans before disposing of them to prevent water from accumulating;
  • Cover basins and water tanks. The thief of the box must have a net that prevents the mosquito from entering, you can use a nylon sock;
