The 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.

由SARS-CoV-2引起的COVID-19暴发引起了人们的关注，因为它的高传播率和迄今为止尚无任何治疗方法。尽管其主要传播途径涉及呼吸道飞沫和直接接触，但也可能通过粪便感染。常规的带消毒的污水处理方法有望消除SARS-CoV-2。但是，对于人口稠密的国家（如印度）污水处理设施较低的国家，污染的机会非常高；由于SARS冠状病毒在未经处理的污水中可以存活数天；甚至在低温地区更长的时间。如果不采取适当的预防措施，全世界大约有18亿人使用被粪便污染的水作为饮用水，那么传播COVID-19的风险预计会增加几倍。
