Mangaluru: CET topper Ananth says, he avoided mobile phone for 2 years

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, June 10: Former minister and Mangaluru MLA U T Khader has hit out at the Karnataka government for what he opined that it is misusing the Epidemic Diseases Act to target opposition parties. 

The statement comes in the backdrop of state government’s move to scuttle oath taking ceremony of KPCC president designate D K Shivakumar.

Asserting that the oath taking will be a grand affair, Mr Khader said that Congress will not be browbeaten by the tactics of the BJP.

Citing the blatant violation of all norms laid down under the Act by minister for health B R Sriramulu at Chitradurga earlier this month, Khader told reporters that the BJP is using the Act for its narrow political gains.

“KPCC has twice deferred swearing in ceremony of Shivakumar after being given the oral go ahead,” Khader claimed, adding the state government must explain to people the issue it has with the Congress organising this function.

Referring to the back-to-back virtual political rallies – one for Bihar and the other for Odisha – on Sunday and Monday that union home minister Amit Shah conducted, Khader wondered if the Act did not apply to the BJP leadership.
