METHODS A case-control study 'cases' being households entomologically confirmed A. infestation; personal interviews Central Havana, a densely populated inner city area characterized by overcrowded housing irregular water service. The participants were residents 278 houses infestation 556 without infestation. RESULTS Greater was lack preventive measures, such as no larvicide tanks (OR = 2.21) use flower vases for religious practice (1.93), not economically active (1.64), vulnerable populations higher risks older people (1.52) children (1.94).
