Govt doctor, who was turned away by 3 Bengaluru hospitals, dies of covid

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, Mar 15: The Karnataka government has intensified screening all international passengers at airports by classifying them into three risk categories.

Passengers, who are symptomatic on arrival fall under risk category 1, those aged above 60 and have Symptoms fall under category 2. Those who fall in both these categories are being quarantined at designated facilities for 14 days from arrival.

Asymptomatic passengers arriving from any of the COVID-19 affected countries will fall under category 3 and will be advised to be under strict home quarantine for 14 days, Medical Education Minister Dr K Sudhakar said here on Sunday.

Bengaluru, Mar 3: Bengaluru mayor Gautam Kumar on Tuesday said that the decision to ban protests in front of Town Hall was made by the council and not only by him.

"The decision to ban the protest in front of the Town Hall was made by the entire council and not only my decision. Also, the things which are approved by the councillor are also read by the ruling party leaders," Bengaluru mayor told media.

"Still it is the discretion of the Commissioner to take a call after the council also. As of now, we have banned any protests in front of Town Hall," he added.

Meanwhile, Congress leaders staged a protest against Bruhat Bengaluru Mahanagara Palike (BBMP) Mayor Gautam Kumar and BJP at Council BBMP building against the decision.

"If people will start protesting, it will badly affect the traffic of the city," said Kumar, while commenting on the protest. If they want to talk about the matter, let us have a healthy discussion. I don't have a problem with and I don't think the ruling party has a problem too," he added.

On Sunday, pro-Kannada activist and former MLA Vatal Nagraj staged a protest in front of Sir KP Puttanna Chetty Town Hall (Bangalore Town Hall) against the decision taken by Bengaluru mayor.

Talking to reporters, Nagraj had said: "He does not know the history of the Town Hall. It is a historic building and protests can be staged there."

"Mayor's decision is against Bengaluru's tradition and culture, that's why we are condemning it and are protesting against this decision. We will not allow Mayor's programs in Bengaluru and he will be shown black flags", he added.
