Karnataka polls: JD(S) endorses CM’s demand for ballot papers, but BJP wants EVMs

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, May 17: A group of 86 college students, who went to Malaysia for internship and have been stranded due to lockdown, have appealed to Karnataka Chief Minister B S Yediyurappa to help them return to Karnataka.

The students in the video have also mentioned Union Minister D V Sadananda Gowda and Kolar MP S Muniswamy and stated that States such as Kerala and Tamil Nadu have made arrangements to bring back their natives from South East Asia.

The students added that they are in the Selangor State of Malaysia. They had arrived there on March 13 for a three-month-long internship as part of their college studies. They are living in apartments arranged by their college and money with them is almost spent, their college is extending them support in this regard. They are not in a position to complete the remaining two months of internship due to lock-down in Malaysia.
