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."

Mangaluru, May 17: A team of staff and students from the Department of Electrical and Electronics Engineering, NMAM Institute of Technology, Nitte, have designed and developed a simple and cost-effective touch-less hand sanitiser dispenser kit at Research and Innovation Centre, Nitte.

According to a release here on Sunday, NITTE said that the most effective medicine for Covid-19 is social distancing, frequent use of sanitiser, and washing hands regularly. In work areas, many people sharing common sanitiser might lead to issues.

The developed product dispenses sanitiser upon sensing the presence of the hand. The product has features like automatic hand detection, indication for power, and sanitiser quantity in the system.

Bengaluru, May 19: In the wake of assurance by Chief Minister B S Yediyurappa to look into their demands, hotels and restaurants in Karnataka today decided to continue takeaway services for three more days.

Hotels were also exempted from the total lockdown on Sundays in Karnataka - under the state guidelines issued for Lockdown 4.0.

The Karnataka Pradesh Hotel and Restaurants' Association (KPHRA) had earlier threatened to stop takeaway services over refusal to allow dine-in facility in the fourth phase of the lockdown. 

B Chandrashekar Hebbar, president of KPHRA said that the CM urged hoteliers to wait for three days, assuring that a decision will be taken. 

"We appraised the government over the mounting losses by keeping just take-away services open. Noting that social distancing and other guidelines will be followed, we urged him to allow dine-in facility," he said.

The Association will wait three more days before discontinuing parcel services, Hebbar said. 

The government also provided relaxation to hotels from the total lockdown announced in Karnataka on Sundays, he said. 

A package for hotel employees such as cooks and waiters, along the lines of those announced for farmers, cab drivers and weavers, was also sought in a petition submitted to the chief minister.

In fact the state government had expressed its willingness to open hotels under the Lockdown 4.0, subject to restrictions. However, the central guidelines do not allow dine-in services.
