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."

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

New Delhi: The Ministry of Home Affairs of Government of India today clarified to the Lok Sabha in a written reply that the so called “Love Jihad” is not defined under the extant laws and no such cases have been reported by any central agency.

It was ministry’s formal response to questions about whether the central government is aware of the observation of Kerala High Court that there is no case of Love Jihad in Kerala.

“The term ‘Love Jihad’ is not defined under the extant laws. No such case of ‘Love Jihad’ has been reported by any of the central agencies. However, two cases from Kerala involving interfaith marriages have been investigated by the NIA,” said the reply.

Communal and anti-Muslim political outfits backed by a section of media often use the term “Love Jihad” to accuse Muslims of marrying Hindu and Christian girls and then forcing them to change religion. Dr Hadiya’s conversion was also termed ‘love jihad’ by the BJP and media. The Supreme Court finally ruled that it wasn’t.

In January 2020, an influential Catholic Church in Kerala had said that “love jihad is a reality” and alleged that scores of women from Christian community from the southern state were being lured into the trap of Islamic State and used in terror activities.

The Viswa Hindu Parishad (VHP) had welcomed the Church statement and called for a united fight against ‘Love Jihad’ in Kerala Society.

The response comes weeks after the MHA, responding to an RTI query, said it has "no information" concerning the 'Tukde Tukde Gang' -- a term that has been used a number of times by PM Narendra Modi and Home Minister Amit Shah to attack opponents.

The RTI application was filed by activist Saket Gokhle on December 26 last year. In his RTI application, Saket Gokhle said Home Minister "Amit Shah addressed a public event in New Delhi, and in his address said, 'The Tukde Tukde Gang of Delhi needs to be taught a lesson and punished'." Gokhle's RTI asked for details of the 'Tukde Tukde Gang'.

The home ministry, in its reply to Saket Gokhle's RTI application, said, "Ministry of Home Affairs has no information concerning tukde-tukde gang."
