Mangaluru: 8-year-old boy dies after getting trapped in lift

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 29: The test report of the man from Uppoor in Udupi district, who committed suicide fearing he had contracted coronavirus infection, has returned negative for the virus.

Health department officials in Udupi said the post- mortem test report had shown that he did not have the virus infection and asked the people in the area not to panic.

Gopalakrishna Madivala (56), had hanged himself on Wednesday suspecting he had the disease, leaving a death note to family members asking them to stay safe.

Ballari, Jan 6: Two members of a family were killed in a cylinder explosion at their home in Sanjeevarayana Kote, here on Monday morning, police said.

The deceased were identified as Parvathi and her daughter Huliyamma.

The incident took place when the two were in the kitchen. Fire tenders were rushed to the rescue.
