Wastewater surveillance can be very effective in anticipating outbreaks of COVID-19 in shelters

A CITF-funded study published in the Canadian Journal of Public Health, from Dr. Sharon Straus (University of Toronto) and her team, shows that wastewater surveillance was an effective technique for detecting an outbreak of COVID-19 in a Toronto homeless shelter before cases were otherwise identified. This process served as an early warning signal and allowed the timely preventive screening of residents.
