While the number of tests for COVID-19 has doubled from an average of 6,000 per day in July to over 12,000 per day now, the number of cases has also risen and the Total Positivity Rate (TPR) of the city remains above 18 per cent.

In the past three weeks, the number of tests done was over 11,000 day. Last week, it crossed 12,000 per day. But the TPR has not reduced. The TPR shows how many patients tested positive among 100 people. It is an indicator that an adequate number of tests are being done. While the World Health Organisation has recommended that the TPR value be below 5 per cent, the Indian Council of Medical Research (ICMR) has said it must be below 10 per cent. The TPR rate was above 28 per cent in June in Mumbai, when an average of 4,408 tests were conducted every day.
