For the first time since the second wave of COVID-19 began, the test positivity rate (TPR) in Chennai on Wednesday dropped below the 5% mark. With 32,168 tests performed and 1,345 cases reported, the TPR was 4.2%.

The last time the TPR was below 5% was 75 days ago in the last week of March. The city was then reporting around 700 to 900 cases a day, while the tests performed were just around 15,000.

From the second week of April, the Greater Chennai Corporation (GCC) gradually began to increase the tests even as cases shot up and the TPR went beyond 20%. Since the second week of May, the tests done daily continuously crossed the 30,000 mark.

The cases, meanwhile, reached a peak in the second and third week of May with May 12 recording the most — 7,564 cases. While cases have now dropped below early-April levels, one month before the peak, the civic body has not reduced testing.
