Sub Inspector Akhtar Khan killed in Dadri encounter

Bengaluru, Apr 19: Karnataka Deputy Chief Minister CN Ashwath Narayan on Sunday said that "only essential and critical number of" employees of the Information Technology (IT) companies will be allowed to work from offices from April 20 onwards in Bengaluru, while others will have to continue working from home.

"Only essential and critical number of employees required will be allowed to turn up. In the next two days, it will be reviewed and a suitable decision will be taken. 

All the details will be communicated to the IT companies," Narayan said here.

Earlier on Saturday, in a meeting to review COVID-19 situation in Karnataka, it was considered that one-third of the employees of IT and biotechnology companies could be allowed to work from the office premises, while the rest should continue to work from home.

Earlier on April 17, the Deputy CM, after holding a video conference meeting with heads of the IT and biotechnology companies, had told reporters that up to 50 per cent of the workforce would have the opportunity to function from office premises after April 20.

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.
