Karnataka Cong to kick-start preparations for bypolls in 17 seats

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.

Mangaluru, Mar 30: In continuing cases of tipplers in the southern states ending their lives due to non-availability of liquor during the lockdown, two men committed suicide in Karnataka's Dakshina Kannada district.

The two suicides were reported in Kadaba taluk on Saturday, police said.

Tomy Thomas (50), a rubber tapping labourer in an estate at Kutrupadi village of the taluk, was found hanging at his rented house on Saturday. Thomas, a native of Kottayam in Kerala, had joined at the estate here a month ago.

Local people said he was desperately moving around in the last few days asking about places where he can get liquor. He had also not reported to work in these days. The body has been kept at the mortuary of a hospital at Deralakatte.

In another incident, a 70-year old man, belonging to Kodimbala village in the taluk, allegedly hanged himself from the branch of a tree near his house at Nakur.

The deceased has been identified as Thomas, who had left his family here 30 years ago and had been working in Kerala. He had returned here only a few years back.

Sources said Thomas, an alcohol addict, was having health problems related to withdrawal. He has been living on pavements at Kadaba without going home.

Kadaba police has registered cases in connection with the two incidents.

Incidents of tipplers committing suicide have been reported in Kerala and Telangana in the past few days. Two men ended their lives in Kerala today while a 50-year old daily wage worker jumped to death from a building in Hyderabad on Friday.
