Coronavirus disease and basic sanitation: too early to be worried?

Abstract INTRODUCTION: Considering that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been detected in feces, this study aimed to verify a possible relationship between basic sanitation indices and coronavirus disease (COVID-19) numbers/rates. METHODS: Data of COVID-19 cases registered in Brazil until May 28, 2020, and independent variables associated with basic sanitation were analyzed. RESULTS: A significant correlation between the number of cases and sewage treatment index/population density was observed. In addition, COVID-19 incidence and mortality rates were significantly associated with the total water service index and lethality rate was significantly associated with the sewage treatment index. CONCLUSIONS: Precarious basic sanitation infrastructure may potentially increase the SARS-CoV-2 transmission in Brazil.

摘要：鉴于严重急性呼吸综合征冠状病毒2型（severe acute respiratory syndrome coronavirus 2, SARS-CoV-2）已在粪便中被检出，本研究旨在验证基础卫生设施指标与冠状病毒病（COVID-19）感染数、发病率之间的潜在关联。方法：本研究分析了截至2020年5月28日巴西境内登记的COVID-19病例数据，以及与基础卫生设施相关的自变量。结果：研究观察到病例数与污水处理指标、人口密度之间存在显著相关性；此外，COVID-19的发病率与死亡率与总供水服务指标显著相关，而病死率则与污水处理指标显著相关。结论：基础卫生基础设施的不完善可能会加剧巴西境内SARS-CoV-2的传播。
