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.

New Delhi, Apr 15:  Union Health Minister Dr Harsh Vardhan on Wednesday said that both Maharashtra and Karnataka are in a bit of trouble due to spike in COVID-19 cases.

"Bihar is not in so much trouble right now, but definitely, Maharashtra is in a bit of trouble, particularly Mumbai and as well as Karnataka," said Vardhan in a video conference meeting while speaking about surge in COVID-19 tally in the country.

"But I was happy to see the confidence of 3 secretaries more particularly when Maharashtra Secretary said with confidence 'we will take care of it'," he said.

According to the ministry, Maharashtra is the worst-affected state with 2,687 cases of which 259 patients have recovered/discharged while 178 patients have lost their lives due to the virus.

Karnataka has confirmed 277 positive COVID-19 cases, including 75 cured and discharged and 11 deaths.

India's tally of coronavirus cases has risen to 11,933, said the Union Ministry of Health and Family Welfare on Wednesday.

Out of the total tally, 10197 cases are active while 1344 patients have been cured/discharged and migrated and 392 people have succumbed to the virus.

Udupi, May 18: As many as eight fresh coronavirus positive cases have been reported in coastal districts of Udupi and Uttara Kannada.
