If the advice by the State’s COVID-19 Technical Advisory Committee (TAC) that the lockdown needs to be continued until the State’s Test Positivity Rate (TPR) falls beneath 5% is taken into account, the State nonetheless has a lengthy option to go earlier than unlocking restrictions. As of now solely two districts, Bidar and Kalaburagi, have a TPR beneath 5%.
Although there was a appreciable decline within the quantity of new instances within the final one week, the State’s common TPR for the final seven days (May 25 to May 31) is 12.79%.
What is worrisome is that the TPR in 20 districts is larger than the State common over the past seven days previous to May 31.

Giridhara R. Babu, member of the State’s COVID-19 Technical Advisory Committee (TAC), who can be the top of Lifecourse Epidemiology on the Indian Institute of Public Health in Bengaluru, stated it can’t be predicted when the TPR will cut back considerably.
“During the second wave, both the ascent and descent of TPR has been more rapid. Different districts are peaking at different times and tests should be increased considerably depending on the test positivity rate in the particular district. TPR will increase when the background prevalence is really high and the number of tests done are less,” he stated.
“TPR is estimated using the formula comprising the number of positive cases in the numerator and the total number of tests done in the denominator. Test positivity will increase when the denominator is small or the numerator is high,” he defined.
C.N. Manjunath, nodal officer for labs and assessments within the State’s COVID-19 job power, stated because the illness can’t be uniform in all districts, graded stress-free of lockdown restrictions will be thought-about when the TPR is between 5% – 10% in a majority of the districts.
“Even when unlocking is considered, it should be in a graded manner with continued restrictions on public, social, and religious gatherings including marriages. Inter-district transport and travel from high-risk to low-risk districts should also be regulated depending on the positivity rate in those districts,” Dr. Manjunath stated.
V. Ravi, TAC member and nodal officer for genomic affirmation of SARS-CoV-2 in Karnataka, stated every district needs to be thought-about individually. “Restrictions should be relaxed in a graded manner in the districts depending on the positivity rate there,” he stated.
Asserting that aggressive testing needs to be taken up in districts with a excessive prevalence, Dr. Ravi identified that every one symptomatic optimistic instances and their contacts needs to be recognized and examined.
