152 - Entomological Surveillance and Control of Aedes aegypti and Aedes albopictus in Rural Districts of São Domingos do Prata, MG

Abstract: Diseases transmitted by Aedes aegypti have a major impact on global public health. In Brazil, dengue transmission has been ongoing since the 1980s, and more recently, Zika and Chikungunya viruses have emerged. While vector control programs are implemented in over 5,000 municipalities, they mainly focus on urban areas and are carried out by Endemic Control Agents (ACE), through home visits targeting mosquito breeding sites.

Community Health Agents (ACS), an essential workforce in Brazil’s public health system, play a key role in health promotion and disease prevention. They conduct regular visits in both urban and rural areas, connecting communities to health services.

São Domingos do Prata, like many municipalities, has rural districts that are far from the urban center but still exhibit the presence of Aedes aegypti and Aedes albopictus, alongside cases of dengue and other arboviruses. These areas remain vulnerable due to insufficient surveillance, making effective control difficult.

This study implemented entomological surveillance using ovitraps in various districts, monitored by ACS for a year. The data collected allowed for the identification of Aedes species, their density, and distribution. This informed control actions focused on community mobilization and environmental management. The collaboration between ACS and ACE improved the effectiveness of services provided to the population.

The study demonstrated a reduction in vector density when preventive measures were implemented. ACS were particularly effective due to their strong community ties and consistent presence in the areas served.

Ovitrap monitoring, supported by well-trained health workers and efficient resource use, proved to be a promising strategy for reducing vector infestation and improving public health outcomes.
