Objective. This study aimed to identify the areas with the highest concentration of traffic accidents and injuries in the San Salvador Metropolitan Area (SSMA). Materials and methods. Traffic accidents were analyzed spatially by point location and by the sum of events in areas of 200 m2. The point location was analyzed by "nearest neighbor analysis", while the areas with the sum of traffic accidents were analyzed by Getis-Ord Gi* to obtain the hot spots. The resulting hot spots with the highest concentration of traffic accidents in the SSMA were evaluated in the field using an observation form to collect data on infrastructure and road safety characteristics. Results. Five areas with the highest number of traffic accidents and injuries, mainly containing primary roads, were identified by analyzing 8191 traffic accidents reported between 2014-2018. Conclusion. The sites with the highest concentration of traffic accidents and injuries were characterized by considerably damaged road infrastructure and the lack of safety systems for drivers and pedestrians. The spatial analysis of traffic accidents and injuries can contribute to improve surveillance and road safety in the SSMA. [ABSTRACT FROM AUTHOR]

Objective.: To determine the hygienic-sanitary factors associated with the microbiological contamination of chicken meat sold at the municipal markets of El Salvador., Materials and Methods.: An analytical cross-sectional study was conducted in 33 municipal markets of the 14 departmental capitals of El Salvador. The sample consisted of 256 out of 456 possible market stalls. A sample of chicken meat was obtained from each market stall. The microbiological analysis was conducted at the National Public Health Laboratory. Frequencies, percentages, measures of central tendency and association were calculated with SPSS version 21., Results.: Escherichia coli was found in 74% of the samples, Staphylococcus aureus in 24% and Salmonella spp. in 1%. The presence of Salmonella spp. was associated with not using hand sanitizer and not using towels for drying the hands. S. aureus was associated with the use of personal accessories and improper storage. The presence of S. aureus was associated with the lack of hand washing, not using a towel to dry the hands and not wearing an apron., Conclusion.: The hygienic-sanitary conditions of the handlers and the market stalls were associated with microbiological contamination of chicken meat marketed in El Salvador.
