NEW DELHI: The national positivity rate for Covid-19 in the total samples tested so far stands at 6.73%, the health ministry said on Monday even as the positivity rate during a single day on Sunday was much higher at 13.4%. In Delhi, the positivity rate has declined from 30% to 10% in the last three weeks, even as testing has improved substantially, data shows.
Officials said the positivity rate for a day is higher because case detection has improved substantially subsequent to rise in daily testing, whereas the average positivity reflects the assessment of overall spread in the country. The rate of positivity is an important indicator in assessing the trend of an outbreak. Experts say the trend whether a community is conducting enough tests.
According to the World Health Organisation (WHO), a positivity rate of more than 10% indicates inadequate testing. Overall, India has tested more than one crore samples so far with over 3.46 lakh samples tested in the last 24 hours. “In Delhi, the efforts were significantly bolstered by the central government to ensure increase in testing.
Tests were ramped up through increased RT-PCR testing along with the new rapid antigen point-ofcare tests which gives results within 30 minutes,” the health ministry said. The average number of samples tested per day in Delhi improved from 5,481 in the first week of June to reach an average of 18,766 samples per day between July 1 and July 5.
The health ministry said that in some states including Karnataka and Rajasthan positivity rate was less than the national average even as they conducted more tests per million of the population. Among the states Punjab reported the lowest positivity rate at 1.92%. On Sunday, 1,80,596 samples were tested and 24,248 fresh positive cases were added to the total count taking the tally to nearly 7 lakh cases.
