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 23: Karnataka Health Minister B Sriramalu on Monday confirmed that there are 27 positive coronavirus cases in the state so far.

A fresh COVID-19 positive case has been reported from Mysore today.

We have also ordered 10 lakh N90 mask, five lakh PPE testing kits, 15 lakh three-layer masks. Sanitizers and thermal scanners will also be purchased on-demand," said Sriramalu while addressing a press conference here.

The Karnataka Health Minister said that decision will also be taken to purchase lab testing kits and equipment.

Meanwhile, Dr Ashwath Marayan, Deputy Chief Minister, Karnataka said that all necessary measures are being taken to contain the spread of COVID-19.

"We will take important decisions as soon as possible. 80 per cent of the companies are following work from home. Critical and essential things should be provided in this situation and we have kept them available to serve the people," said Marayan.

"We have taken all the required decisions including the logistics and supply. Social distancing is much important and we will implement it," he added.

The total number of positive coronavirus cases in the country mounts at 415, according to the Indian Council of Medical Research (ICMR).
