Airport bomb: Home minister refuses to call Aditya Rao a terrorist, accuses Opposition of appeasing minorities

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, Apr 19: In order to boost the Coast Guard's (CG) surveillance and reconnaissance capabilities on the country's west coast in Karnataka, CG OPV Varaha and CG Dornier 785 ex Kochi were pressed to service to undertake extensive surveillance.

"Both seawards and aerial surveillance of Karnataka coast line will be undertaken from Sunday," said S Babu Venkatesh, Commander, Coast Guard, Karnataka. The surveillance will be an air-sea coordinated operation.

The Coast Guard ships and aircraft maintained extensive search in the area for intercepting any suspect vessel. Indian Coast Guard ships classified various contacts in the area and kept them under constant surveillance.

Bengaluru, Mar 8: The Indian Council of Medical Research (ICMR) has identified three more locations to open Viral Research Diagnostic Laboratories (VRDL) including in Mysuru, Hassan, and Shivamogga in Karnataka.

According to a statement issued here on Sunday, these laboratories will start functioning shortly in Mysuru Medical College and Research Institute, Hassan Institute of Medical Sciences, and Shivamogga Institute of Medical Sciences. Besides, the ICMR has also identified sample collection centres in Vijayanagar Institute of Medical Science in Ballari and Kalaburgi Institute of Medical Sciences.

B G Prakash, State Joint Director (Communicable Diseases), said that the new Laboratories will help to ease the load on the two designated laboratories in Bengaluru. Currently, the virology laboratory in Bangalore Medical College and Research Institute and the NIV branch in Rajiv Gandhi Institute of Chest Diseases are doing COVID-19 tests in Karnataka.
