‘We know to set afire like Hanuman’: B L Santhosh warns beef eaters

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.

Udupi, Feb 10: The throat swabs of three suspected coronavirus patients in Udupi that was sent for tests have come back as negative.

Throat swabs of three persons who got admitted at a district government hospital in Udupi with symptoms of fever on Friday was sent to Bangalore medical college and research institute for test to know whether the admitted persons who returned from China 15 days back had contracted coronavirus.

The 30-year-old man from Kaup taluk had been China on personal work and had returned to Udupi 15 days back. Upon showing the symptoms of fever, throat pain and cold, he was suggested to get admitted.

He was admitted in the isolation ward and was directed to remain under quarantine till the observation period ends and till the test report is obtained.

Another family from Mandarthi, a man and his wife, who had returned after a tour from China 15 days back were also kept under observation at the isolation ward in the district government hospital, Udupi.

Udupi DC G Jagadish has said that there are no coronavirus case reported in Udupi and people need not panic. Sources said that the three tested negatives for coronavirus in Udupi will be discharged from the hospital on Monday.
