Bengaluru, Mar 10: With concerns growing by the day, the Karnataka government is readying three more labs to test throat swab samples.

Currently, only two labs in Bengaluru — National Institute of Virology and Virus Research and Diagnostics Laboratory (VRDL) lab attached to Bangalore Medical College and Research Institute — are categorised biosafety level 2+, a requirement for coronavirus tests.

Now, the government is working on upgrading three more labs, one each in the government medical colleges at Hassan, Mysuru and Shivamogga. “The labs will be ready within one week,” the authorities said.

Currently, the labs are testing only throat swab samples of suspected patients and taking 24 hours to give the results. “A patient’s blood sample will be collected only if he or she tests positive for covid-19 infection in the first throat swab sample.

While earlier the state would send all samples of suspected coronavirus cases to NIV, Pune, the two labs were upgraded to biosafety level 2+ in mid-February.

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.

Bengaluru, Apr 28: With fresh guidelines on the COVID-19 lockdown expected soon, Karnataka Chief Minister B S Yediyurappa on Monday chaired a meeting with key ministers, officials and Deputy Commissioners of districts and discussed about re-starting economic activities in the state, as he took stock about of the pandemic.

"At the video conference with DCs, CM took stock of COVID-19 situation and measures taken to control its spread. Discussions also happened regarding starting of certain economic activities in parts of the state," official sources said. The state government would take any decision in this regard after the Centre issues fresh guidelines or directives, they said, without elaborating.

The meeting came hours after Prime Minister Narendra Modi held a video conferencing with Chief Ministers to discuss the situation arising due to COVID-19 in the country, which is under lockdown since March 25 to contain the pandemic. Only nine chief ministers spoke in the virtual meeting with the Prime Minister and Yediyurappa did not get an opportunity.

A senior Minister, who attended the meeting told PTI, necessary directions regarding the lockdown after May 3, they were likely to come in a couple of days.

"Most of the Chief Ministers wanted the lockdown to continue to contain the spread.... nothing concrete emerged, but we expect the necessary directions will follow in couple of days. This is what we expect after seeing what has happened as a followup to three to four such video conferences in the past," he said.

The Minister said the larger opinion was that the current measures should continue and interstate or inter-district movement should not be allowed. Regarding movement within the districts that are green zone, some decision may be taken soon, he said, adding the Prime Minister also asked states to concentrate on reforms, aimed at attracting investments in the days to come.
