Ragpicker finds bag carrying Rs 1,000 notes of 52K face value

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, Jul 19: Three legislators of the opposition Congress in Karnataka, including 2 MLAs and 1 MLC tested positive for coronavirus and are under treatment, a party official said on Saturday.

"Our Bailhongal MLA Mahantesh Koujalgi in Belagavi district and Humnabad MLA Rajashekhar Patil and his MLC brother Chandrashekhar Patil in Bidar district tested positive for the infection and are under treatment at designated hospitals," party spokesman Ravi Gowda told media persons in Bangaluru.

Koujalgi's swab sample was taken on Friday after he showed signs of illness and its result turned positive earlier in the day.

"As Koujalgi attended a review meeting at Bailhongal, about 20 officials who participated in the meeting have been home quarantined," said Gowda.

Koujalgi is the second lawmaker in the state's northwest region to test positive after BJP's Belagavi North assembly segment MLA Anik Benake tested positive for the virus on July 15.

"Patil brothers were in self quarantine after meeting BJP's Bidar Lok Sabha member Bhagwanth Khuba, who tested positive on Wednesday. Their tests also showed they were infected with the virus," Gowda said.

Congress MLC Sandesh Nagaraj, who tested positive on Friday, is under treatment at a private hospital in Mysuru.

Dakshina Kannada district Youth Congress president Mithun Rai is in institutional quarantine in Bengaluru after he tested positive for the infection.
