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.

Mar 11: The Karnataka government on Wednesday started a campaign called 'Namaste over Handshake' that encourages people to greet in the traditional Indian style, to tackle the spread of coronavirus.

The campaign also includes health advice on how people can protect themselves from the infection by adopting hygiene practices such as regularly washing hands to prevent the spread of COVID-19.

As part of the campaign, the state health and family welfare department has uploaded a poster on the social media, featuring a 'Bharatnatyam' dancer draped in a red saree saying 'Namaste'.

"Use Namasthe to greet others, fight against corona" read a message on the poster online.

The poster has health helpline numbers (104 and 011- 23978046) for public queries on the viral disease, which has claimed 4,251 lives worldwide.

A health department official told PTI that as part of the campaign, posters have been uploaded on social media and it would be printed and despatched to different districts to be put up at important junctions.

"We had been working on this idea. Kerala has already done it. They are using Kathakali dancers whereas we are using a Bharatanatyam dancer as our model," the official said.

Medical Education Minister K Sudhakar too had insisted that people should adopt 'Namasthe' or 'Namaskara' to greet people instead of handshakes or hugs.
