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.

Wayanad, Apr 21: Panic gripped residents of Mananthavady and Mepaddi regions of the district after several cats in the region were found dead.

A group of people approached authorities after which the Animal Husbandry Department tested samples from the carcasses and found that the cat deaths were caused by Feline Parvovirus, which does not transmit to humans.

Speaking to ANI, Dr D Ramachandran, Chief Veterinary Officer, Wayanad said that Feline Parvovirus affects cats and vaccines are available to protect cats and keep the virus at bay.

"There were incidents of cat deaths in Mananthavady and Meppadi region of Wayanad district creating panic among the local residents. The officials of the Animal Husbandry department visited the spots for epidemiological investigations. The samples were collected and sent to the State Institute of Animal Diseases, which confirmed that the deaths were due to Feline Parvovirus. There is no need to worry as this virus does not spread to humans," he said.

A cat owner in Meppadi said that within a span of two-three days, over 13 cats had died in the region.

"We are afraid of these sudden cat deaths amidst coronavirus outbreak. We have informed the Health Department and Animal Husbandry department. Officials came here and collected the samples," she said.

Kalaburagi, Apr 20: With no COVID-19 case reported here on Sunday, the total number of virus-infected people in the district stood at 22.

While three persons have succumbed to the infection in the district so far, three others have been cured and discharged.

"No COVID-19 case was reported in Kalaburagi district today. Total 22 positive cases and 3 deaths have been reported in the district till date. Three persons have been cured," said District Magistrate B. Sharat.

Karnataka's total count of coronavirus patients has surged to 390, said the State Health Department on Sunday.
