Hong Kong research using sewage to detect Covid-19 could track other diseases

A technology developed by Hong Kong that uses sewage monitoring to detect Covid-19 could be deployed to track other diseases such as flu and dengue fever, researchers have found, with the method already adopted by about 100 cities in mainland China.

Researchers from the University of Hong Kong (HKU), who developed the technology during the coronavirus pandemic, said sewage contained far more significant information than the mere flow of waste.
