Tokyo begins sewage study for signs of COVID-19 spread

Tokyo, May 13 : The Tokyo metropolitan government Wednesday began a study into whether sewage samples can be used to detect signs of a spread of novel coronavirus infections.
To prepare for an expected second wave of COVID-19 infections, the metropolitan government aims to establish a method to analyze sewage for the virus in cooperation with the Japan Society on Water Environment.
Similar research has already started in the United States and France.
The metropolitan government will collect 300 milliliters of treated and untreated sewage samples once a week at 15 sewage treatment plants in the Japanese capital.
 The samples will be frozen and stored until ways to extract the coronavirus and analyze it are established. Samples for the research will be collected until the coronavirus state of emergency is lifted.
