RESUMO

Introduction: OMS recommended America, in the year of 2004, implement and to improve specific systems of epidemic surveillance of the rickettsiasis, characterizing the areas of transmission of the different offences and investing in active epidemic and environmental surveillance. Those zoonosis are related to the fundamental factors of the urban expansion, as well as to the population increase of vectors and hosts in contact with the human population. In the areas called Vale do Paraíba from State of São Paulo there is no situation of recognized endemy, however this presents environmental and socioeconomic similarities with other recognized endemic areas of the State of São Paulo, no rare it is the occurrence of ticks described as vectors of diseases and it happens important exchange of people with work and leisure purposes there, besides with frequent international flow. Method: Evaluation of potential risk of zoonosis transmission by ticks in selected categorized areas. Through environmental information, the prevalence of vector ticks and accessibility of the human population to infested areas, a scale for characterization of the risk was build. Results: In 252 areas of the 6 districts of the Vale do Paraíba, in the Estado de São Paulo, on period between may/2008 and march/ 2009, they were found 7.800 adult ticks, also nymphs and larvas, many of which in family nurturing of rabbits and hen houses. The final classification pointed 42,5% of the inspected areas corresponding to the situation of imminent risk of transmission of zoonosis by ticks. Other 33% correspond to limited risk in the scale. In the remaining 24% of the studied area the classification went potential risk for transmission of tick related rickettsiasis. Recommendations: For the imminent risk areas, it is recommended that the local health services maintain proper vector surveillance and educational programmes for its populations. For the limited risk areas, it is recommended the maintenance of a proper vector surveillance routine and also the inclusion of an environmental surveillance. For the areas under potential transmission risk of those illnesses, priority elaboration of vectors control strategies is strongly recommended with proper engagement of all local health services, as well as the population. The enhancement of the articulation with the regional services and professional veterinarians is fundamental. Besides, an adequate structuring for the local health services administration, with rational and efficient managing of material and human resources, is indispensable.
