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.

Mysuru, Jan 2: Mysuru-based Karnataka State Open University is gearing up to offer courses online from this year onwards and a proposal in this connection will be placed before the University Grants Commission (UGC) this month, after approval from the board of management.

As of now, the university offers 31 courses, including undergraduate, postgraduate, and diploma programmes.

Vice-chancellor Vidyashankar S Said that the university will submit its proposal to the UGC soon.

“This is being done to make learning convenient and help students study their courses of choices from the comfort of their homes.”

After launching online admissions for courses, this is another step to go paperless and towards an e-campus, the V-C explained.

The university has also proposed to launch 12 new courses for 2020-21.

A proposal in this regard will be placed before the board for approval on Thursday and the same will be submitted to the UGC for its nod.

Prof. Vidyashankar said the these courses will be in addition to the 31 already available.

The new courses include LLM, MA in Education, BBA, BSc, BCA, diploma in Information Technology, postgraduate diploma in Information Technology, BSc in Information Technology, MSc in Information Technology, MSc in Botany, PG diploma in Banking and Insurance, MSc in Zoology, MA in Telugu, Executive MBA, and MSc in Food Sciences and Nutrition.

The new courses had been proposed based on students’ feedback and the trend.

The V-C said the admissions for the January cycle have begun and over 380 students had so far taken admissions online.

“We are hoping for good admissions this cycle and are expecting around 12,000 admissions,” he replied.
