A few weeks ago, the Central Pollution Control Board also told the government that infection could be spread through sewage pipeline. In such a situation, PPE kits and debris have to be considered to be disposed of properly, although the Central Pollution Control Board has also expressed the possibility of spreading the infection through sewage. There has been no confirmation of this.
Research in china
Last year, a report by sciencedirect also expressed fears that the virus could be spread through the drain pipe in the bathroom. A team of researchers from the China Center for Disease Control and Prevention (CCDC), University of Utah and Nanjing Medical University conducted research on the infection of SARS-CoV-2. It was confirmed in the report that if someone is infected in an upstairs flat, there will be viruses in the pipeline coming out of his bathroom and toilet, although how these viruses will reach humans is still a secret.
