Misuse Of Pesticides Can Harm The Fight Against Dengue


The indiscriminate use of aerosol insecticides to combat dengue may pose harm to the environment and reduce the effectiveness of control programs the mosquito Aedes aegypti, which can become more resilient. “Just orient the use of insecticides when no evidence of transmission of dengue, as evidenced by epidemiological criteria,” says the Secretary of Health Surveillance, Ministry of Health, Jarbas Barbosa.

Barbosa explains that this type of application can only be accomplished by means of specific equipment, such as coastal motor, which resemble backpacks used by agents, or mounted on vehicles, known as smoke.

The secretary also warns that the application of these products in dengue control should be made only by surveillance teams of state and municipal departments of Health, who are trained in the safe handling of these products. The guidelines of the ministry are in agreement with the World Health Organization (WHO).

In a statement released by the Technical Secretary of the Ministry of Health Surveillance, Ministry of Health draws attention to the action of the residents of the city of Foz do IguaƧu (PR), who were instructed to use these products to cope with the disease. “The distribution of pesticides for the population is devoid of any scientific evidence that it works to prevent dengue outbreaks, and therefore not recommended by the Ministry of Health,” the statement said.

On the other hand, the Ministry of Health considers most effective for the prevention and control of dengue measures of physical elimination of mosquito breeding places of disease, such as sealing of water tanks, clearing gutters, among others.
