NEW DELHI: Holding out hope amid rising
, the all-India positivity rate, total confirmed cases per 100 tests, measured over a 14-day period, showed a declining trend for three consecutive fortnights — from a high of 11.23% between July 15-28 to 8.84% during August 1-14 and now at 7.87% (between August 14-27) though states like Maharashtra,
and Chhattisgarh remain worries.
Maharashtra, accounting for almost 22% of India’s 34 lakh confirmed cases till Friday, continued to show a positivity rate of 20% over the last 14-day period, between August 14-27. After briefly moderating at 16.5% between August 1-14, Maharashtra’s positivity rate has risen, indicating a worrying spread of the disease. Barring the first half of August, the state’s positivity rate has been over 20% since June 5.
A positivity rate of 5% or below over a 14-day period is considered a ‘green zone’ where a state can safely relax lockdown measures. Anything above that mark is considered a ‘red zone’. Also, higher the positivity rate, more likely that only the sickest are being tested and a large infected population remains untested and points to the disease spreading.
In the latest TOI study, Maharashtra, Andhra Pradesh, Karnataka, Chhattisgarh, West Bengal, Tamil Nadu and Delhi, in that order, had the highest positivity rates. Andhra Pradesh had a positivity rate of 17% in the August 14-27 period, followed by Karnataka with 14%, Chhattisgarh and
with 9% each, Tamil Nadu with 8% and Delhi with 7%.
Delhi again seems to be slipping back into the red zone with its positivity rate climbing for the first time after remaining at around 6% for two consecutive fortnights till August 14.
Chhattisgarh has emerged as a new hotspot with its positivity rate in the latest fortnight reaching 9%. In the previous two fortnights, the state had a positivity rate between 5% and 6%. Tamil Nadu has shown some promise with its positivity rate declining for three successive fortnights from a high of 10% during July 15-28 to 9% between August 1-14 and down to 8% during August 14-27.
