Since SARS (Severe Acute Respiratory Syndrome) has previously spread through defects in the building’s sewage pipe system, scientists are increasingly concerned about the spread of the new coronavirus disease (COVID-19) within and between buildings.
On March 23, the international medical journal The Lancet Global Health published an online newsletter arguing that one of the great risks of the spread of the virus was that the wastewater pipeline system would connect parts of the building, and that, The air contaminated by the virus may move unhindered in buildings.
The paper also discusses some measures to reduce the spread of viruses through wastewater pipeline systems, including paying close attention to the functionality of water sealing devices in U-shaped elbows in home appliances, and treating cracks or leaks in pipelines in a timely manner.
It is worth noting that on the afternoon of March 25, Zhong Nanshan, head of the high-level expert group of the National Health and Reform Commission and a member of the Chinese Academy of Engineering, participated in the China-EU Anti-Epidemic Video Conference to exchange new crown pneumonia strategies with experts from Germany, Italy, the United Kingdom, Romania and other countries. Considerations for national experts also include the need to keep sewers open.
