Key findings

The study highlighted significant differences in sanitation between two areas of Estrutural City: one with and one without sanitation facilities. Water quality analysis in areas without sanitation found dangerous levels of contamination, including total coliforms and Escherichia coli, beyond safe limits. Dengue incidence was also higher in these areas, emphasizing the urgent need for interventions to improve sanitation and mitigate health risks in vulnerable communities.

• Research evidence on Ae. aegypti frequency and density in a low-income area in Brasilia

An 11-month entomological survey in 60 houses in Estrutural revealed a high density of Ae. aegypti mosquitoes, underscoring the impact of poor sanitation and water quality on mosquito prevalence in the area.

• New strategic approach to identifying mosquitoes of interest

A new app was developed to identify Culicidae in 26 mosquito species across 11 genera. The app was available from app stores until October 2023; training was provided for scientists and professionals on how to use the tool effectively.

• Health education activities for water storage, garbage disposal and installation of a voluntary waste delivery station

Despite delays in building a solid waste facility due to elections, the Urban Cleaning Service installed garbage disposals at key locations in unserviced areas. Engagements with residents highlighted the need for trash cans and bags for effective waste management, leading to awareness campaigns on proper garbage disposal practices.

• Understanding population experiences regarding water, vectors and the intersection of the two

The research uncovered valuable knowledge within the community on dengue vectors, detailing factors contributing to mosquito identification, as well as dengue prevalence, and existing prevention efforts. These insights pave the way for effective arbovirus control strategies in high-risk areas, reinforcing public health policies and essential services for at-risk communities.
