'If Hindu, then why promote eating beef?' Yogi asks Siddaramaiah

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, Mar 3: Chief minister BS Yediyurappa on Monday introduced the Karnataka Municipalities and Certain Other Law (Amendment) Bill, 2020, in the assembly to give voters the opportunity to reject candidates in civic polls.

The bill, if passed, will enable election officials to offer the NOTA option in the elections to municipal corporations on the lines of assembly and Lok Sabha polls.

An amendment bill which seeks to enable the government to set up a separate university for the districts of Raichur and Yadgir was also tabled. The government said the workload of Gulbarga University necessitated creation of a separate university for the two districts, a move that will also help reduce regional imbalance in Kalyana Karnataka region.

Another amendment bill seeks to allow industrial units, which have failed to start operations on allotted land after seven years, to sell off the parcels to another unit. Bills which empower authorised agencies to regulate turf clubs and horse racing and regulate salary and pension of teachers in higher education institutions were also introduced in the assembly on Monday.
