Patient dies as BJP leader holds up ambulance for half an hour

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.

Jan 31: President Ram Nath Kovind on Friday hailed the contentious Citizenship Amendment Act as "historic" in his address to joint sitting of both houses of Parliament, prompting protests by some opposition members.

He also said that debate and discussion on any issue strengthens democracy while violence during protests weaken it.

"The Citizenship Amendment Act is a historic law. It has fulfilled wishes of our founding fathers including Mahatma Gandhi," he said.

"Debate and discussions strengthen democracy, but violence during protests weaken democracy," he said without directly referring to the anti-CAA protests in the country some of which have witnessed violence.

In a reference to abrogation of Article 370, Kovind said there is happiness among people of India that people in Jammu and Kashmir and Ladakh have got rights on par with the rest of the country.

The president said Parliament has created record in the first seven months of the new government headed by Narendra Modi by enacting several landmark legislations.

"My government is taking strong steps for making this decade as India's decade and this century as India's century," he said.
