To develop a method to assist in the design and assessment of animal rabies control campaigns.
A methodology was developed based on geographic information systems to estimate the animal (canine and feline) population and density per census tract and per subregion (known as "Subprefeituras") in the city of São Paulo (Southeastern Brazil) in 2002. The number of vaccination units in a given region was estimated to achieve a certain proportion of vaccination coverage. Census database was used for the human population, as well as estimates ratios of dog:inhabitant and cat:inhabitant.
Estimated figures were 1,490,500 dogs and 226,954 cats in the city, i.e. an animal population density of 1138.14 owned animals per km(2). In the 2002 campaign, 926,462 were vaccinated, resulting in a vaccination coverage of 54%. The estimated number of vaccination units to be able to reach a 70%-vaccination coverage, by vaccinating 700 animals per unit on average, was 1,729. These estimates are presented as maps of animal density according to census tracts and "Subprefeituras".
The methodology used in the study may be applied in a systematic way to the design and evaluation of rabies vaccination campaigns, enabling the identification of areas of critical vaccination coverage.
开发一种方法以协助设计和评估动物狂犬病防控活动。
基于地理信息系统开发了一种方法，用于估计2002年巴西东南部圣保罗市每个普查区和每个次区域（称为“Subprefeituras”）的动物（犬类和猫类）数量及密度。通过估计给定区域内的疫苗接种单位数量，以实现一定比例的疫苗接种覆盖率。使用人口普查数据库获取人口数据，以及犬与人、猫与人的估计比例。
该市估计有1,490,500只犬和226,954只猫，即每平方公里有1138.14只家养动物的动物种群密度。在2002年的活动中，有926,462只动物接种了疫苗，疫苗接种覆盖率为54%。若平均每个单位接种700只动物，要达到70%的疫苗接种覆盖率，估计所需的疫苗接种单位数量为1,729个。这些估计以按普查区和“Subprefeituras”划分的动物密度地图形式呈现。
本研究中使用的方法可系统地应用于狂犬病疫苗接种活动的设计和评估，有助于识别疫苗接种覆盖率关键区域。
