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, May 2: The Centre’s classification of districts created confusion in Karnataka as the state’s own categorisation deviates significantly from the health ministry’s list.

For instance, the Centre put the number of districts in the red zone in state at three, while the state Covid-19 war room puts it at 14. Bengaluru Urban and Mysuru figure in the red zone in both lists. While Bengaluru Rural with zero active cases on May 1makes it to the Centre’s red-zone list, it is in the orange zone according to the state.

In addition to these two, the state classifies Belagavi, Kalaburagi, Vijayapura, Bagalkot, Mandya, Bidar, Dakshina Kannada, Chikkaballapura, Dharwad, Gadag, Tumakuru and Davanagere as red-zone districts.

State Covid war-room authorities said they would take a look at the Centre’s criteria for classification and take a call. Besides, incharge Munish Mudgil pointed out that states are allowed to make additions to the red and orange zones. According to the Centre’s list, Karnataka has 13 districts in the orange zone and 14 in the green zone.

Sudan said, “the districts were earlier designated as hotspots or red zones, orange zones and green zones primarily based on the cumulative cases reported and the doubling rate. Since recovery rates have gone up, the districts are now being designated across various zones duly broad-basing the criteria.

This classification takes into consideration incidence of cases, doubling rate, extent of testing and surveillance feedback. A district will be considered under the green zone if there are no confirmed cases so far or if there is no reported case in the past 21 days.”

Bengaluru, Feb 20: German software group SAP said on Thursday that it had temporarily shut down its offices across India for sanitisation after two employees in its Bengaluru Ecoworld office tested positive for H1N1 virus.

"Two SAP India employees based in Bangalore (RMZ Ecoworld office) have tested positive for the H1N1 virus. Detailed contact tracing that the infected colleagues may have come into contact with is underway," SAP India said in an emailed statement.

The company said its offices across Bengaluru, Gurugram and Mumbai have been closed for extensive sanitisation. All employees based in these locations have been asked to work from home till further notice

SAP India also advised its employees to seek medical advice if they or their family members have any symptoms of cold, cough with fever.

H1N1 or swine flu can spread through air. Its symptoms are cough, fever, sore throat, running nose, body ache, headache, chills and fatigue.
