CHENNAI: Even as Chennai Corporation intensifies surveillance on passengers return from the UK due to new strain of the virus, the city’s test positivity rate (TPR) has fallen down further to less than 3%.
As per latest data from the corporation, the TPR, the percentage of samples that return positive and a measure of the spread of the infection, has come down below 3% in the last few days.
For instance, the TPR on Thursday was 2.4%. It must be recalled that during the months of May and June, TPR was in the range of 25-30% on many days. It has gradually decreased over the months. Medical experts say that testing should be at a limit where the TPR is 5%.
