RESUMO
In response to the recent cholera outbreak, a public health response targeted high-risk communities, including resource-poor communities in Port-au-Prince, Haiti. A survey covering knowledge and practices indicated that hygiene messages were received and induced behavior change, specifically related to water treatment practices. Self-reported household water treatment increased from 30.3% to 73.9%.

OBJECTIVE: Geographical information systems are valuable tools for studying tuberculosis (TB) epidemiology, but have been underused for the evaluation of TB control programs. We aimed to compare the geographical distribution of TB before and after the five elements of directly observed therapy, short course (DOTS) were strengthened in a Health Jurisdiction in Mexico in response to recommendations made by the WHO Global Tuberculosis Program. METHODS: All consenting persons detected by passive case finding between March 1995 and February 2000 who were confirmed to have acid-fast bacilli (AFB) in sputum underwent clinical and laboratory evaluation. A TB 'episode' was defined as the period of time between bacteriological diagnosis and treatment discharge by the local control programme. Distances of TB episodes from the nearest urban centre were determined according to recent transmission and multidrug resistance (MDR). RESULTS: During the first half of the study period, MDR episodes were located a median distance of 1.24 km from urban centres, which did not differ significantly from non-MDR episodes (1.14 km, P=0.56). In contrast, the median distance of MDR episodes increased 55% to 1.92 km during the second half, which placed them significantly further away out than non-MDR episodes (1.08 km, P=0.01). No changes in location were detected for recent transmission. CONCLUSION: While reinforcing the TB control programme reduced the incidence of MDR, the remaining episodes were located in poorer and more remote areas.
