ABSTRACT

Objective. To describe the outbreak of dengue and to study, at the same time, the trace that this illness followed in this region Otomí-Tepehua of Hidalgo, Mexico.
Materials and methods. The operational definition of probable cases of dengue was: any person with fever of 38°C, or higher, during five days, compatible with a viral infection. For data collection, a questionnaire was developed, looking, house by house, for probable cases in the town of San Antonio el Grande. Venous blood samples were taken from people who met the operational definition. A questionnaire was also applied to collect information related to the entomological indexes. The study and initial control of the outbreak took place from May 12 to May 18, 2008.
Results. The index case occurred on April 14. In an interview, the case said that he had traveled between the 20^th and 28^th of March to endemic localities of the state of Puebla. Cases of dengue began in San Antonio el Grande (n 194), extended to 7 locations, followed by San Gregorio (n 58) and Acuatla (n 11), which surround the initial outbreak. The other localities followed the only dirt road leading to San Antonio el Grande, and this was the route the dengue followed.
Discussion. The population movement favors a permanent risk for the spread of dengue endemic areas, it adds to environmental conditions and changes in mosquito behavior and adaptability, plus it has become a carrier of different serotypes of the causal virus. In this situation the Pan American Health Organization developed guidelines for the prevention and control of the disease and Aedes aegypti, which represent various components of joint implementation. On the other hand, dengue vaccines are currently under development. Thus, vector control at the moment is the only method available to combat dengue fever and dengue hemorrhagic fever. This can be achieved, based on knowledge of ecology, and technical assurance of adequate entomological surveillance.
