“…The increase in the supply of artificial shelters represented by buildings, such as tunnels, cisterns, abandoned or inhabited houses, manholes, deactivated coal furnaces, among others, have contributed to the spread of rabies (8,9). Spatial analysis is a widely used tool in ecological studies, which allows mapping and demonstrating locations of risk for disease development and evidence of its association with various factors, represented living organisms and physical environment (10,11). Geographic Information Systems (GIS) have been used to improve the control and monitoring mechanism of outbreaks and shelters of the main rabies transmitters, being an efficient way to prevent and act on eventual outbreaks of the disease (11,12).…”

The vampire bat Desmodus rotundus is the main transmitter of domestic herbivorous rabies, which causes economic losses in cattle raising, being a serious public health problem. The use of Geographic Information Systems (GIS) allows the spatial monitoring of these bats shelters, which is an efficient way to prevent and control rabies. This study located shelters of D. rotundus in the Eastern Center region of São Paulo state and identified the types of shelters used (natural or artificial), their proximity to water, sexual composition, and population estimated of the colonies. Searches were carried out by colonies of vampire bats in natural and artificial shelters during 2002 to 2004, covering 18 municipalities. After located, the shelters were georeferenced, being recorded the nature of the shelter (natural or artificial), use (shelters of males, maternities, digestive) and estimated population. The data were incorporated into a GIS, producing a thematic map of the shelter’s location and their distance from the local water bodies. There were found 1.567 D. rotundus distributed in 94 shelters, where only six shelters (6.38%) were natural (caves). Most shelters (79.78%) were sparsely populated, with up to 15 bats, including male shelters (46 shelters) and 30 maternities (63.82% of maternities). Five shelters (5.37%) had between 50 and 100 bats and only two shelters (2.15%) had a population greater than 100 bats. Six shelters (6.38%) were inhabited houses, which is a concern for public health, as these may constitute a source of dangerous contamination for domestic and human carnivores. All the shelters were at a distance of up to 2 km of rivers or streams. The high percentage of artificial shelters found is a consequence of the intensification of the anthropic changes that increase the supply of food and shelter to D. rotundus, which associated with a large drainage network favors the dispersion of this species of bat in the region. The proximity of all D. rotundus shelters to the drainage network corroborates other studies in São Paulo state, where the areas close to the main rivers generally favor the existence of a larger number of shelters.
