Summary Objective To characterize the social and environmental risk factors associated with the presence of Aedes aegypti in order to improve community dengue control. Methods A case–control study with ‘cases’ being households with entomologically confirmed A. aegypti infestation; personal interviews in Central Havana, a densely populated inner city area characterized by overcrowded housing and irregular water service. The participants were residents of 278 houses with infestation and 556 houses without infestation. Results Greater risk of infestation was associated with lack of preventive measures, such as no larvicide in the water tanks (OR = 2.21) and use of flower vases for religious practice (1.93), not being economically active (1.64), vulnerable populations with higher risks in households with older people (1.52) and households with children (1.94). Conclusions Efforts to reduce infestations should continue to focus on water tank sanitation and improving housing conditions, but also engage community religious leaders to help promote safe practices. Vulnerable populations should be especially targeted by prevention activities. A surveillance programme can produce evidence to guide interventions.
