BARBOSA, Gerson Laurindo et al. Larval infestation indicators and influence of population size on dengue transmission in the State of São Paulo, Brazil: an ecological study in the periodo 2007-2008. Epidemiol. Serv. Saúde [online]. 2012, vol.21, n.2, pp.195-204. ISSN 1679-4974.  http://dx.doi.org/10.5123/S1679-49742012000200002.

OBJECTIVE: to describe larval indicators and analyze the association of occurrence of dengue and population size and distance between municipalities in the State of São Paulo, Brazil. METHODS: ecological study utilizing larval indicators according to property type and logistic regression. The data was obtained from the systems of Endemics Control Bureau and Center of Epidemiological Vigilance in 2007 and 2008. RESULTS: household Index Infestation andpositivity of Strategic Points and Special Property were higher in municipalities with dengue. The chance of occurrence of dengue in municipalities less than 50km away from the major municipalities was twice as likely. The municipalities with populations greater than 50.000 inhabitants hadfive times more chance of dengue occurrence compared to the small municipalities. CONCLUSION: this study emphasizes the importance of adopting control strategies based on entomological indicators, especially in big municipalities.
