Congress leaders stage protest against VHP

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 20: Karnataka State Road Transport Corporation (KSRTC) had to confront an unprecedented situation as there was a commotion at bus stands in various parts of the state due to the mad rush of passengers.

Deputy Chief Minister Laxman Savadi, who is in charge of the transport department, admitted that there were some shortcomings in the arrangements. He, however, was confident that things would improve from Wednesday.

As against the dearth of passengers in the bus stands in Bengaluru a day ago, Wednesday witnessed an overwhelming crowd blaming BMTC authorities for not providing enough buses for all the destinations on time.

Some of the employees who were asked to report to duty before certain time were facing difficulty in reaching the office in the absence of bus despite having daily pass and arriving at the stand well in advance.

Authorities were finding it difficult to convince the public as a bus could ferry only 35 passengers at a time which was way less than the demand.
