CM did not warn me, he just asked me to convince my brother: Mohiuddin Bava

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."

Bengaluru,  Jun 19: Following the coronavirus outbreak, Bengaluru's Kempegowda International Airport has introduced ultraviolet treatment while scanning outbound baggage apart from other measures to enhance passenger and staff safety.

"Two custom-designed UV tunnels have been created to disinfect trolleys after every use. Two custom-designed UV tunnels have been created to disinfect trolleys after every use. These Tunnels are located at a cordoned-off area of the Terminal," according to a statement by the Bangalore International Airport Limited (BIAL).

The airport plans to use an ultra-low volume (ULV) spray treatment for check-in bags: all outbound passenger baggage is sanitised before dispatch to the aircraft

Authorities also plan to minimise use of additional trays for footwear by introducing specially designed trays; the trays that are in use are UV treated and sanitised manually after every use.

Officials are currently in the process of implementing silver nano-coating for frequently used touchpoints for self disinfection like check-in counters, Immigration counters, ATRS trays, etc. Currently, sanitisation of high-traffic areas and frequently touched surfaces continues to be done every thirty minutes manually without disrupting the flow of passengers.

All high-traffic areas are sanitised once every three hours by using ULV machines - eight times in 24 hours.

Washrooms across the Airport premises are sanitised on a regular basis with dedicated manpower, irrespective of the frequency of use. 456 units of tabletop hand sanitiser and 107 units of sensor-based hand sanitisers have been placed across the Terminal.

120 biowaste bins located across the Airport campus enable passengers and staff to dispose of their masks, gloves and other PPE conveniently and safely. This bio-waste is managed by a dedicated team and handed over to a Pollution Control Board-approved vendor and taken away for incineration.

The Airport said that the passenger feedback for the contactless process has been positive. "The objective of the process is to minimise physical contact and enhance passenger throughput," it said.

These sanitisation measures come in light of the highly infectious COVID-19 pandemic which spreads through person-to-person contact. Small droplets from the nose or mouth can spread the virus when they land on objects and surfaces around the person.

Bengaluru, Jun 8: Facing a shortage of labour, some top builders in the city have initiated efforts to bring back the migrant workers, who have returned to their native places following the COVID-19 lockdown, and are holding parleys with Railway authorities for operation of special trains to ferry them.

After the lockdown was announced, many construction projects came to a halt and accordingly the labourers were rendered jobless. These migrant workers preferred to go back to their home state as they were not paid when the projects were stopped and were caught in the big financial mess. Many of these migrants even chose to cover thousands of kilometres by foot when even trains, buses or any motor vehicles were not operating.

Keeping their woes in view, the Centre decided to run the Shramik Special trains to ferry them to their native places. But, after they were gone, the builders found themselves in a lurch. An executive of a builder told PTI "Yes, our builder and a few others are in talks with the Railways to run the special train to bring back the labourers." She said nothing has been materialised as of now.

According to her, the builders took the contact numbers of the workers when they left the city to their home states and are now contacting them one by one. The South Western Railway has so far sent 3.11 lakh migrant workers in 216 Shramik Special trains starting from May 3 to June 6.
