全世界有超过20亿人无法获得经改善的卫生设施，无法充分保留或处理粪便。这导致含有肠道病原体的粪便物质污染环境（包括家庭地板）的可能性。本研究旨在评估地板类型和卫生习惯如何影响家庭地板上粪便污染的浓度。在秘鲁伊基托斯市城郊社区的63户居民中，采集了189个地面样品，进行了大肠杆菌菌落形成单位（CFU）的检测。大肠杆菌，和家庭进行了评估，他们的水，环境卫生和个人卫生的特点。多元线性回归结果表明，改善卫生条件和厨房区水泥地板的家庭，粪便污染减少到卫生条件未改善和泥土地板的家庭（β：-1.18 log（10）E。coli CFU/900 cm（2）; 95%置信区间[CI]：-1.77，-0.60）。没有共用卫生设施的家庭与共用卫生设施的家庭相比，厨房地板的污染程度也较低（Beta：-0.65 log（10）E。coli CFU/900 cm（2）; 95%CI：-1.15，-0.16）。这些研究结果表明，家庭的卫生设施可能会影响地板上的微生物负荷，从而导致家庭地板可能成为粪便病原体传播给儿童的间接途径。
Over two billion people worldwide lack access to an improved sanitation facility that adequately retains or treats feces. This results in the potential for fecal material containing enteric pathogens to contaminate the environment, including household floors. This study aimed to assess how floor type and sanitation practices impacted the concentration of fecal contamination on household floors. We sampled 189 floor surfaces within 63 households in a peri-urban community in Iquitos, Peru, All samples were analyzed for colony forming units (CFUs) of E. coli, and households were evaluated for their water, sanitation, and hygiene characteristics. Results of multivariate linear regression indicated that households with improved sanitation and cement floors in the kitchen area had reduced fecal contamination to those with unimproved sanitation and dirt floors (Beta: -1.18 log(10) E. coli CFU/900 cm(2); 95% confidence interval [CI]: -1.77, -0.60). Households that did not versus did share their sanitation facility also had less contaminated kitchen floors (Beta: -0.65 log(10) E. coli CFU/900 cm(2); 95% CI: -1.15, -0.16). These findings suggest that the sanitation facilities of a home may impact the microbial load found on floors, contributing to the potential for household floors to serve as an indirect route of fecal pathogen transmission to children.
