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.
