CHENNAI: From registering just under 1000 new COVID-19 cases every day for a period of 22 days, new cases in Chennai have gradually risen since September 24, touching almost 1300 a day. However, the percentage of active cases in the city has remained almost the same.
The percentage of active cases in a day -- referring to the number of people undergoing treatment for COVID-19 on a given day -- is now at 7%, only slightly higher.
From September 3 to 5, the city had 9% active cases overall, gradually decreasing to 8% between September 6 to 10 and then 7% between September 11 and 16. It then further decreased to 6% from September 17 to 27 before going back up to 7%, which has been maintained until Friday.

After a short spell where the city had no streets as containment zones, meaning no three index cases were registered in the same street or more than three families tested positive in the same street, the city had 10 streets under containment since Friday.
