Yeddyurappa govt should get No. 1 award for corruption: Amit Shah!

Bengaluru, June 22: Even as the covid-19 positive cases are steadily increasing in Karnataka, an expert has claimed that community transmission has begun in Bengaluru and cases could keep rising over the next two months.

“If you look at the natural course of this virus across countries around the world, it is about six months. Now we’re in the fourth month. This will go on for another two months. It also sounds like this is the beginning of the peak. There is also a possibility of the number of cases going up from now on. Even across India, cases are increasing,” says Dr CN Manjunath, director of Sri Jayadeva Institute of Cardiovascular Sciences and Research and State Task Force member.

Besides the increase in number of cases, the virus is advancing silently, stealthily. A lot of people who are testing positive are asymptomatic. In areas like Padarayanapura, Nanjangud and many places in north Karnataka, there have been positive cases who have not had any contact with infected individuals. Some cases recorded in Bengaluru over the last two to three days have not had any contact with Covid-positive people.

Dr Manjunath adds: “We are in community transmission. This will happen because nature is ahead of everything. We have to take all possible precautionary measures at our command. This has to happen. Only then some kind of herd immunity will be developed.”

“We are expanding the guidelines of testing to include a large number of people to be tested. Now, according to the Indian Council for Medical Research (ICMR) guidelines, only symptomatic Influenza like Illness (ILI) or Severe Acute Respiratory Infection (SARI), or a person coming in contact with an infected person are being tested.

But since we have crossed 100 days in Karnataka from the first reported case and we’re getting cases with no travel history or contact with a Covid-positive person, we have to start random testing across the sub-group population. Only then will we understand the burden of the disease and what precautions need to be taken,” he says.

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, Apr 28: A local court in Karnataka on Tuesday granted bail to a CRPF commando who was arrested by state police officials for alleged assault on them during COVID-19 lockdown duty, a charge contested strongly by the paramilitary.

The jawan has been taken to the jungle warfare training school of the paramilitary force in Belagavi district, a senior official said.

Constable Sachin Savant of the 207th CoBRA battalion was granted regular bail by a court located in Chikodi taluka of the district, he said.

A team of CRPF and CoBRA officials were present in the court during the proceeding during which the state police did not oppose the bail, the official said.

The commando was arrested by police on April 23 from Examba village (Belagavi district) when he was washing his bike outside his house without wearing a mask, as required under the coronavirus prevention protocol.

An altercation and physical fight took place between the two sides, following which the trooper was taken to the local police station and arrested.

The Central Reserve Police Force (CRPF) had on Monday taken up the case with the Karnataka director general of police (DGP), calling the incident "unpleasant".

The CRPF letter said commando Savant was "manhandled, ill-treated, paraded to the police station barefooted, kept in chains and handcuffs" by police personnel and sought the intervention of state Director General of Police Praveen Sood.

The paramilitary had said that from the scrutiny of a viral video on social media of the incident "it is apparent that the conduct of the police personnel was not citizen-centric".

A police report had said the CoBRA commando "started the altercation" with the beat constable and another policeman accompanying him, and "assaulted" them.

As per the official Twitter handle of the Karnataka DGP's on Monday evening, "IGP (inspector-general of police) Belagavi has been asked to enquire into the incident involving the CRPF constable and action will be taken against guilty after receipt of the report".

The Commando Battalion for Resolute Action (CoBRA) unit of the CRPF specialises in guerrilla tactics and jungle warfare.
