39-yr-old woman, 42-yr-old brother end lives by self-immolation in Bantwal

Bengaluru, Mar 4: Seeking to allay fear among the citizens in the wake of Coronavirus scare, Karnataka Health Minister B Sriramulu on Wednesday made an appeal to the people not to pay heed to rumours spreading on social media.

In a series of tweets, Mr Sriramulu assured people that the government has taken adequate measures to ensure that the disease does not spread further. "Don't lend your ears to rumours about the Coronavirus in the social media. Rely only on the authentic information," he tweeted.

The minister's tweet came as Bengaluru reported the first case, after a techie from the city with a travel history to Dubai and interaction with Hong Kong-based people there, was admitted to a hospital in Hyderabad.

As panic gripped the city, Mr Sriramulu said the apartment where the software engineer was staying has been sanitised. Besides, his 25 colleagues have been identified. One of them has been admitted to the hospital as a precautionary measure and his blood sample has been sent for lab test.

"So far 40,207 people have been screened at the International airport. 251 blood tests have been done, of which 238 were found negative, while the rest of the reports are yet to come," Mr Sriramulu tweeted.

The health department said three people have been admitted to the isolation ward at the Rajiv Gandhi Institute of Chest Diseases (RGICD).

Meanwhile, a parent appealed to people not to panic about the Coronavirus in the techie's apartment, where his son too resides. "My son is from the same apartment. To update everyone, there is absolutely nothing wrong here. It was more of panic on social media that created this," he said in a message.

He said that the man who is in Telengana and testedpositive stayed in this building on February 21. "His roommate was taken to hospital and has tested negative," he said. It is been two weeks since the incident. The virus cansurvive only for 48 hours under optimal conditions, he noted. "Everyone in this building is safe. Please educate yourself. Refrain from spreading panic and misinformation." he added.

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.
