Abstract
After the identification of the first SARS-COV-2 infected cases in China, the virus was rapidly disseminated among the distinct continents and the COVID-19 pandemics was announced by the WHO in March 2020. Over time, the epidemiological sceneries varied among countries, according to the adopted mitigation measures and epidemic phase. Recently, a recrudescence of the epidemics has been observed in distinct countries. SARSCoV- 2 can be transmitted by direct or indirect contact. The viral RNA has been detected in stool and other clinical specimens from infected patients and a putative fecal-oral transmission has been argued. Viruses are shed in human excreta, further disposed into the sewerage system or into the environment, in poor sanitation settings. Thus, SARS-CoV-2 RNA has been regularly detected in wastewater and surface water impacted by the direct discharge of sewage. Some studies have reported an association between climatic parameters and an increase in COVID-19 incidence. However, conclusive evidence based in full seasons is needed so far.
