Although the mobilization of health authorities is focused on combating COVID-19, the population must also prevent mosquitoes Aedes aegypti, which transmits to dengue, zika and chikungunya. To assist in the elimination of the vector, the City of Belo Horizonte will use drones to map breeding sites and launch larvicidas in difficult to access places in the capital.

According to the latest bulletin released by PBH on July 24, more than 4,000 cases of the disease were confirmed in the capital of Minas Gerais and one confirmed death, while another 45 cases of chikungunya were recorded and over 42 zika.

To combat the Aedes aegypti mosquito, which transmits diseases, the Belo Horizonte City Hall will launch drones in places difficult to reach by agents and residents. Gutters, roofs, slabs and empty buildings, according to Ministry of Health, concentrate 80% of breeding sites.

According to PBH, the resource will be used to locate the outbreaks and pass it on to the Epidemiological monitoring of the organ. When the risk is identified and the authorization of the property owner is obtained, the product used to combat the larvae will be coupled to the drone and activated on the spot. The agency reported that the substance has no toxicity, does not contaminate the environment and is recommended by the Ministry of Health. In addition, it is already used by the Municipal Health Department.

According to the director of zoonoses the Belo Horizonte Municipal Health Department, Eduardo Gusmão, the city’s expectation with the new tool is that it will be incorporated into the work routine of the field teams. “It will direct the actions to eliminate potential creators even more effectively and in a timely manner. From an aerial perspective, teams are able to map locations of higher risk for the development of aedes much more quickly and thus better direct efforts to promote the elimination of this health risk ”, he explains.

The action is expected to start in the second half of August and should last for 12 months. The use of drones is a partnership between the Belo Horizonte City Hall and the mining company Vale.


Amid the pandemic of the new coronavirus, some measures were taken to prevent the spread of the disease during visits by zoonotic agents. According to Eduardo Gusmão, dengue prevention activities have remained in BH, even during the pandemic.“Some adjustments were necessary in the routine of field agents. All professionals must respect the distance of 1 meter, wear a protective mask, wash their hands after each visit, carry out an inspection only in the external areas of the buildings and avoid the exchange of materials ”, he points out.

He also adds that the signature on the visit bulletin by the residents was also cut from the routine to avoid the exchange of materials. * Intern under the supervision of sub-editor Ellen Cristie.
