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 26: Karnataka chief minister BS Yediyurappa has been urged to cancel the proposed SSLC examinations in Karnataka and allow “mass-pass” for every student in the wake of covid-19 crisis. A group of intellectuals and educationists have put forth this demand.

In the letter released by educationist VP Niranjan Aradhya, said that they were listing the scientific reasons to the CM for cancellation of exams which are slated to be held from June 25 to July 4th.

In the letter, the intellectuals have elucidated a number of reasons for cancelling the upcoming exams. “There are close to 8.5 lakh students and 2.5 lakh staff involved. If we include parents who would drop their kids at the exam centre, around 30 lakh people will be involved in the process, making it a risky affair. Though the government has said that it will separate the students with fever or other ailments, will students admit to having fever? What if they consume paracetamol and come to write exams?” asks the letter. 

Added to this, the question papers have to be sent from the district and taluk centres and there may be chances of transmission.

“Even if we conduct exams, then what about the students who have failed? Every year, around 2.5 lakh students fail in the exam. Will the government conduct the supplementary exams again? The whole process of conducting exams comes at a huge cost of Rs 20 cr to Rs 25 crore. Hence, we are suggesting that the government cancels the exams and pass the entire group of student en masse,” said the letter.

Mangaluru, Jun 26: In a gut-wrenching incident, a pack of stray dogs attacked a herd of barking deer, also known as Indian muntjac at Dr Shivaram Karanth Biological Park at Pilikula on the outskirts of the city last night.

Dhama H Jayaprakash Bhandary, director of the biological park said: “Due to heavy rains a tree was uprooted damaging the compound wall of the park one day ago. Last night pack of stray dogs entered the park and attacked the barking deer. When the incident came to light, 10 barking deer had lost their lives and many others were injured.”

He said that five years ago they had rescued four barking deer that bred and multiplied to 40. “We had planned to release some of the barking deer to jungle and retain around a dozen in the park. Last night’s incident has shocked us,” he said, adding that the injured barking deer are being treated.
