Rich haul of gold seized at Mangaluru Airport in January

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.

Mangaluru, Mar 27: Amid fear of coronavirus spread, the District Collector on Friday ordered the closure of the city’s major fishing area Dhakke.

''The fish caught by us on Wednesday were dumped, without being sold'', fishermen said. Meanwhile, a few them obtained police permission and took the fish to the nearby fish mill.

All the boats which had gone for fishing are back to the dock and the port is deserted. Also, the fishermen who went fishing have been advised to return.

Mangaluru, Mar 25: A full-fledged control room was set up at the Deputy Commissioner's office in Mangaluru to collect all information about the suspected patients.  

The control room will function under the guidance of KIADB special land acquisition officer.  

All the details on those who arrived from foreign countries via Mangalore Airport, via airports in other districts, primary and secondary contacts of the people who arrived from foreign countries are being compiled at the control room.
