‘Entire world should embrace Islam’: Out-of-context clip of Om Puri goes viral

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 30: The coronavirus scare has taken a toll on the poultry industry in Karnataka with many poultry farm owners culling the birds, insiders in the poultry industry said.

At least one lakh birds have been culled in the last one week, the sources said.

Ever since the news spread about novel coronavirus spreading rapidly, the poultry industry started feeling the heat.

The lockdown spelt further trouble for the industry with reduced business compelling farm owners to go in for the culling.

According to Muddukrishna of C N Nischchith Enterprises, a live chicken dealer in Bengaluru, the culling had taken place in Shivamogga, Kolar and other places.

"There is a drastic decline in business. There are neither customers nor enough supply of birds for sale. We are badly hit. There are many poultry farm owners who have incurred tremendous loss due to the lockdown," Muddukrishna told news agency.

Another major poultry industry owner, having his farms in Channapatna, Ramanagar, Anekal and surrounding places, said he had to get rid of at least 4,000 birds in each of these farms.

"This is not restricted to me alone. There are about 64 major poultry industries who have gone for the drastic measure of culling," said the farm owner.

He said in the last one week, at least one lakh birds have been culled as it was hard for them to maintain them.

"Each bird needs at least a kilogram of grains in three days to eat whereas each kg of poultry food costs about Rs 32. We have about two lakh birds in our farm. How can we maintain if there is no business," rued the poultry farm owner.

The industry has suffered a double whammy.

People gave up eating chicken following rumours that the novel coronavirus COVID-19 is similar to SARS, another virus.

Further, the lockdown has blocked the transportation of these birds, he added.

According to the farm owner, in the last one month, he had suffered a loss of around Rs 15 lakh and if the situation continues for the next three months, his condition would be beyond imagination.

Muddukrishna said the poultry farm association had given a memorandum to the animal husbandry and fisheries department seeking direction on the transportation of these birds.

Accordingly, the secretary in the department of Animal Husbandry and Fisheries A B Ibrahim issued a circular to all the city police commissioners, deputy commissioners of the district, superintendent of police and the CEO of Zilla Panchayath on Friday that the animal husbandry services have been declared as essential services.

Ibrahim said in his circular that the production of chicken birds, sheep, goat, pigs, etc in the farm and their transportation, manufacturing feed, liquid nitrogen meant for veterinary use and other items related to the Animal Husbandry should be permitted.

"Despite the order, our vehicles are stopped and drivers are harassed," alleged Muddukrishna.
