I am confident of easy victory; PM Modi too has appreciated my work: Simha

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, Jul 14: More than 80 Namma Metro workers have tested positive for COVID-19 in Bengaluru on Tuesday, said Yashwanth Chauhan BL, public relations officer of Namma Metro.

"All safety and treatment protocols would be followed at the camps," he added.

These workers were staying in a camp near Nagavara-Gottigere lane, reach-6 of phase two. More than 200 contract workers of Larsen and Toubro who had come from different states have been tested after a labourer complained of fever.

All coronavirus positive workers were shifted to a COVID care centre while others were kept in isolation as per the guidelines.

Bengaluru, May 27: A yet incomplete state-wide survey has revealed that there are over 53.99 lakh households vulnerable to the infection in Karnataka. The survey is being conducted by the government to find COVID-19 vulnerable population particularly with comorbidities and cases like SARI and ILI.

The survey, which is 67.16% complete so far, finds 1.37 lakh households across Karnataka have people with comorbid conditions, excluding a further 13,341 households with symptoms of Influenza Like Illness (ILI), Severe Acute Respiratory Infection (SARI) and Covid-19.

Over 48 lakh households have senior citizens, who on account of their age are at highest risk of death from the disease.

Munish Moudgil, Director of the State COVID War Room, clarified that households could have multiple types of vulnerable people. According to the survey data (which is dated May 26), Kalaburagi and Bengaluru Urban have the highest cases of SARI, ILI with 1,902 households and 1,703 households respectively, although these numbers are likely to rise, as the survey is still incomplete in these districts. 

A BBMP source said that 68% of the survey has been completed in the city, but the data has not been logged yet. The number of SARI/ILI cases is next highest in Shivamogga with 1,217 households, Mysuru with 1,200 and Davangere with 1,178.

The government regards SARI and ILI as indicators of coronavirus and on April 17, had passed an order instructing healthcare workers to test people with these conditions for the coronavirus. Consequently, 51 COVID-19 cases were discovered by testing people with these symptoms.

Belagavi, meantime, has reported the highest incidents of households with comorbid conditions with 12,427 identified so far, followed by Mandya with 9,289, Kalaburagi with 8,311, Shivamogga with 8,140 and Bengaluru Urban with 7,562. Importantly, 3,45,443 vulnerable people have been identified in Bengaluru Urban within 28.26% of data logged in so far.
