Coronavirus disease 2019 (COVID-19) outbreak: some serious consequences with urban and rural water cycle

Abstract

AbstractThe COVID-19 outbreak due to SARS-CoV-2 has raised several concerns for its high transmission rate and unavailability of any treatment to date. Although major routes of its transmission involve respiratory droplets and direct contact, the infection through faecal matter is also possible. Conventional sewage treatment methods with disinfection are expected to eradicate SARS-CoV-2. However, for densely populated countries like India with lower sewage treatment facilities, chances of contamination are extremely high; as SARS-CoVs can survive up to several days in untreated sewage; even for a much longer period in low-temperature regions. With around 1.8 billion people worldwide using faecal-contaminated source as drinking water, the risk of transmission of COVID-19 is expected to increase by several folds, if proper precautions are not being taken. Therefore, preventing water pollution at the collection/distribution/consumption point along with proper implementation of WHO recommendations for plumbing/ventilation systems in household is crucial for resisting COVID-19 eruption.
