Congress, JD(S) pretend to fight each other but are in tacit alliance: PM Modi

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, Jul 25: Kalmane Kamegowda, the lake man who was recently praised by Prime Minister Narendra Modi during a recent Mann Ki Baat, is in serious condition after he tested positive for COVID-19, former Karnataka Chief Minister HD Kumaraswamy said on Saturday.

"The health condition of Lake Kamegowda is serious. It is our responsibility to save him. I demand that the state government make appropriate arrangements for emergency treatment," Kumaraswamy tweeted.

"The Prime Minister also praised him in Mann Ki Baat. Chief Ministers expressed appreciation. Only praising doesn't help him at this point of time. The government needs to come forward to treat him in a good hospital when he's sick," he said in the following tweet.

Kamegowda of Dasanadoddi village in Malavalli taluk had drawn the attention of the Prime Minister in the 66th 'Mann Ki Baat' for constructing ponds to conserve rainwater during the summer.

Responding to Kumaraswamy's remark, State Medical Education Minister Dr Sudhakar K said that he has already called up the Mandya Medical College and directed the hospital to admit and treat Kamegowda.

"As soon as I noticed the seriousness of Kamagowad's health, I called the director of the Mandya Medical College and informed him that he should be admitted to the hospital and treated. I pray to the Lord that the Kamagowadas who inspire the whole country will heal soon," Sudhakar K tweeted.
