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, July 13: The Karnataka government today announced the cancellation of I PUC supplementary examinations across the state. 

Primary and Secondary Education minister S Suresh Kumar announced that the government took the decision in the wake of rising cases of Covid-19 and re-introduction of the lockdown. According to sources in the education department, as many as 60,000 students were supposed to appear for the examination.

Previously, the state government had decided to hold these exams at the college level in every district and publish the results by 30 July. However, the government has withdrawn even that arrangement and completely cancelled the exams. 

According to the minister, all the students who failed in the I PUC examination, shall also be promoted to II PUC. "The students who have attended all the subjects but unable to pass the exams will also be promoted to the next class," Suresh Kumar said.

However, those who missed out on the exams due to health reasons or failed in the examinations will be given a small test at the time of commencing classes for II PUC to assess their learning ability at the college level, according to the minister. "Only those students who missed out on the examination due to shortage of attendance will not be promoted to the next class," Suresh Kumar clarified.

New Delhi, Mar 19: The Supreme Court on Thursday upheld the validity of Karnataka's 2018 reservation law, which granted reservation in promotion to employees belonging to SC and ST categories.

A bench headed by Justice DY Chandrachud holds that applications filed by a group of general category employees for applying 'post-based quota' and the principle of the creamy layer at entry-level in public employment are not maintainable.

The apex court had, in November last year, reserved its order on the applications filed by general category candidates in the matter.

In May last year, the top court had upheld the law allowing reservations in promotions for SC and ST candidates with consequential seniority.
