Abstract

Introduction: Hospitals are important for vector control of endemic diseases.

Methodology: To investigate the presence of dengue vectors, 30 locations at a university hospital in Cuiabá, Mato Grosso, Brazil, were monitored from January to December 2009 for mosquito eggs using ovitraps placed in high-traffic internal and external areas.

Results: A total of 2,302 eggs were obtained. Positivity rate at different sites ranged from 50.0% to 0.0%, with the highest indices in external areas. The presence of eggs correlated with increasing humidity (r = 9.81; p = 0.0013).

Discussion: The study aimed to detect and verify the infestation level of the dengue vector and the influence of abiotic factors.

Conclusions: The results indicate that this hospital may be considered an environment for the spread of dengue and hence strategic actions, including control measures and programs aimed at preventing the transmission of this vector, must be implemented.
