Sewage-based surveillance suggestion
Testing wastewater samples for the coronavirus could help local authorities to identify and tackle COVID-19 outbreaks sooner, scientists say. Studies in the United Kingdom suggest that this approach could help to detect infection spikes up to ten days earlier than existing medical-based tests. “By sampling wastewater at different parts of the sewerage network, we can gradually narrow an outbreak down to smaller geographical areas, enabling public-health officials to quickly target interventions,” says pollution scientist Andrew Singer. “It seems obvious that we should be doing this.”BBC News | 5 min read
