Pune Sewage Reveals COVID-19 Signals, Similar to Past Surges
Scientists in Pune are checking the city's sewage water to look for signs of COVID-19.
They've found the virus in all the sewage treatment plants since the start of May.
This is similar to what they saw before past surges of the virus, giving them an early warning.
The scientists can't tell exactly which version of the virus is present, but the amount they find helps them watch how the virus is spreading.
They share this information with health officials so they can get ready for any potential increase in cases.
It helps track the spread through the community.
COVID-19 viral presence has been detected in all 10 sewage treatment plants (STPs) in Pune since early May.
Wastewater surveillance by NCL reveals patterns similar to those before previous surges.
The first positive sample was detected on April 22.
