A recent review paper from an international research group involving Hokkaido University and the University of Yamanashi in Japan shows how wastewater could provide a useful tool for monitoring COVID-19 and highlights the further research needed to develop this as a viable method for tracking virus outbreaks. This research was published in Science of the Total Environment.
