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 3: Undergraduate and postgraduate students skipping online classes held by their universities run the risk of being debarred from writing their exams. 

State universities, which are monitoring the attendance of online classes, are asking their affiliate colleges to send the monthly online attendance details and this would reflect in their regular attendance. This would apply to those studying professional courses like medicine and engineering. 

State medical education minister Dr K Sudhakar has asked all medical colleges to regularly send attendance details to the Rajiv Gandhi University of Health Sciences (RGUHS).

RGUHS vice-chancellor Dr Sachidanand confirmed to DH that the varsity is indeed monitoring the attendance of students. “Online classes are equal to classroom teaching. (Such method of conducting classes) are necessary during the Covid-19 pandemic and the nationwide lockdown,” he said.

According to the Supreme Court directions, students should have 75% attendance to be eligible to appear for the final exams. There could be relaxations if they have health issues. If students are bunking online classes, it would reflect on their minimum attendance necessary to appear for the exams, the vice-chancellors of state-run varsities said.

Bangalore University vice-chancellor Prof K R Venugopal said most of the students are attending online classes and teachers are messaging the parents of those who are irregular. “(Of course) if they fall short of the minimum attendance, they won’t be allowed to appear for the exams,” he said.

Bengaluru North University vice-chancellor Prof T D Kemparaju said the administration has asked its teachers to record details of students attending online classes and update the university.

Mixed signals 

Meanwhile, the University Grants Commission (UGC) on Wednesday issued guidelines directing all universities to treat the lockdown period as “deemed as attended” for students and research scholars. Experts pointed out that the order would prompt students not to take the online classes seriously.

“Arrangements have been made at the state varsities to make students attend online classes compulsorily and students are also serious about it. Now, because of the UGC guidelines, they may bunk classes,” said the vice-chancellor of a state-run university.
