Relationship of Climatological Variables With Confirmed and Suspected Cases of the Dengue Vector

Dengue is endemic in Mexico, with epidemic cycles occurring approximately every three to five years, associated with the introduction of new viral serotypes into susceptible populations. This study analysed the relationship between climatological variables and dengue incidence in Morelos, Mexico, during the period 1999–2009, aiming to identify favourable conditions to inform territorially focused prevention and control measures, using spatial analysis methods. The analysis of the influence of climate on dengue transmission in Morelos demonstrated the importance of precipitation in developing early warning systems for potential epidemics. It is recommended that territorially focused preventive strategies be implemented, such as the elimination of breeding sites, fumigation, and social mobilisation in areas at risk due to environmental, social, and epidemiological factors.
