Bengaluru, Mar 19: To better enforce social distancing and prevent further spread of Covid-19, the Karnataka health and family welfare department on Wednesday said it will "stamp the back of the palm" of international passengers advised to be on home quarantine, along with the date they are allowed to get out of home. The stamping process began at 12am Thursday.

Pankaj Kumar Pandey, commissioner, health and family welfare, said: "It is noted that a few passengers under home quarantine are not following the instructions. Therefore, it has been decided to stamp the back of the palm of their left hand with a specially designed stamp which will indicate the last day of quarantine."

He said the special stamp will use an indelible ink and "airports in Karnataka have been instructed to follow this without fail". On average, about 3,000 people are arriving in Bengaluru on international flights every day.

The department said social distancing is the only known method of combating the spread of Covid-19 and added, "International passengers are segregated as symptomatic and asymptomatic."

High-risk flyers kept at mass quarantine unit

The symptomatic passengers (Group-A) are taken to designated hospitals; asymptomatic ones, depending on the port of origin, are taken to the quarantine centre or permitted to go on home quarantine.

At the mass quarantine centre, the asymptomatic passengers are divided into moderate-risk (Group-B) and high-risk (Group-C) categories.

“The high-risk passengers are kept at a mass quarantine centre for medical observation. The moderate-risk passengers are being sent for home quarantine where they need to spend 14 days,” the statement added.

Pandey said: “International passengers changing flights within the country cannot be stopped. Ideally, they should be stamped at the first port of entry when they arrive from a foreign country which is not happening.” He said this issue will be brought to the notice of the Directorate-General of Civil Aviation.

Bengaluru, Apr 28: Karnataka has found that the rapid antibody test kits for COVID-19 that the Centre supplied to the state have only 47% sensitivity. The state will be returning the kits to the Indian Council of Medical Research (ICMR).

Karnataka had received 11,400 rapid antibody test kits from the ICMR a few days back, out of which it had sent around 200 of them to NIMHANS for validation.

After the ICMR, on Monday, sent a circular to all states to return the test kits to the suppliers, Dr CN Manjunath, Director, Jayadeva Institute of Cardiovascular Sciences and Research, and nodal officer for lab testing in the state's COVID-19 task force, said, "We have cancelled the orders we placed to Guangzhou Wondfo Biotech and Zhuhai Livzon Diagnostics for one lakh rapid antibody test kits. Since the ICMR supplied us with 11,400 kits out of the 6.5 lakh kits it procured, we will be returning the kits to them."

Manjunath told said that the validation at NIMHANS revealed the kits to have only 47% sensitivity. Sensitivity is the ability of a test to identify the true-positives in a population, i.e., the actual number of people who've been infected with the disease. With the rapid antibody testing kits being shelved, the state's plan to randomly test high risk groups has taken a backseat. 

So far, the state has tested 43,791 samples. 

Karnataka now has 22 testing facilities -- 14 government and seven private labs. Many private labs have not tested any samples so far because of the lack of test kits (the state has made it clear that it will not provide test kits to private labs). So, getting an ICMR approval for testing has become a moot point.p

Agreeing to the setback the state's plans of ramping up testing has taken, Manjunath said, "It is true that RT-PCR test kits are in shortage. Even Pune's Mylabs had a shortage in supplying test kits. But we are relying on institutes like Kidwai, Narayana Health and Biocon's Syngene that have received approval for testing. They're big institutes and we hope that they will test a large number of samples."

On reports that the Centre has RT-PCR test kits that will last for only a week, he said, "We have test kits that will last for eight to 10 days. We have ordered for more. We are hoping to receive them before the current kits run out."
