Epidemiological study of brucellosis in eight Greek villages using a Computerised Mapping Programme

A Computerised Mapping Programme (CMP) was created step by step to cover al l the needs of a cross sectional population survey conducted in eight villa ges of Fokida, a rural area of central Greece. The maps of Greece (boundary ) and the topographical maps of the eight villages were created using the C MP. A volunteer sample of 1121 out of 2607 inhabitants of the study area pa rticipated in the population survey. The participants were tested for bruce llosis using serological tests (ELISA and Rose Bengal) and the intradermal reaction test. A questionnaire was used to obtain information concerning th e risk factors for brucellosis. The risk factors found through statistical analysis were occupation (RR: 5.81, p < 0.00001), consumption of raw milk ( RR: 1.98, p < 0.001) and unpasteurised fresh cheese (RR: 2.13, p < 0.01). T he same factors were indicated by the CMP. The CMP also indicated manure-co ntaminated playgrounds in residential yards as a potential risk factor for children. The origin and dissemination were delineated using time-space ass ociation display. The CMP proved to be a useful tool in this epidemiologica l study.
