Traces of Covid-19 can be successfully detected in sewage, helping to give health officials an early warning of local outbreaks of the virus, the British government said.
A project, originally launched in June, has now proved that fragments of genetic material from the virus can be detected in waste water, indicating if a local community or institution is experiencing a spike in cases, according to Reuters.
The government said this would allow health officials to identify large outbreaks especially where there were carriers not displaying any symptoms and to encourage people to get tested or take precautions.
