There is a lack of research investigating the confluence of risk factors in urban slums that may make them accelerators for respiratory, droplet infections like COVID-19. Our working hypothesis was that, even within slums, an inverse relationship existed between living density and access to shared or private WASH facilities.
In an exploratory, secondary analysis of World Bank, cross-sectional microdata from slums in Bangladesh we investigated the relationship between intra-household population density (crowding) and access to private or shared water sources and toilet facilities.
The analysis showed that most households were single-room dwellings (80.4%). Median crowding ranged from 0.55 m per person up to 67.7 m per person. The majority of the dwellings (83.3%), shared both toilet facilities and the source of water, and there was a significant positive relationship between crowding and the use of shared facilities.
The findings highlight the practical constraints on implementing, in slums, the conventional COVID19 management approaches of social distancing, regular hand washing, and not sharing spaces. It has implications for the management of future respiratory epidemics.
缺乏对城市贫民窟中可能使其成为 COVID - 19 等呼吸道飞沫感染加速器的风险因素汇聚情况的研究。我们的工作假设是，即使在贫民窟内，居住密度与使用共享或私人水、环境卫生和个人卫生设施之间也存在反比关系。
在对世界银行提供的孟加拉国贫民窟横断面微观数据进行的探索性二次分析中，我们研究了家庭内部人口密度（拥挤程度）与使用私人或共享水源及厕所设施之间的关系。
分析表明，大多数家庭居住在单间房屋中（80.4%）。拥挤程度中位数从每人 0.55 平方米到每人 67.7 平方米不等。大多数住宅（83.3%）共享厕所设施和水源，拥挤程度与共享设施的使用之间存在显著的正相关关系。
研究结果突出了在贫民窟实施常规 COVID - 19 管理方法（如保持社交距离、定期洗手和不共享空间）所面临的实际限制。这对未来呼吸道传染病的管理具有启示意义。
