BJP’s star campaigner Yogi to address over 30 rallies across Karnataka

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 27: A 65-year-old coronavirus patient who died in Karnataka this morning after apparently contracting the infection on a train ride has raised concern about community transmission of the highly contagious disease.
The man, the 60th coronavirus patient in Karnataka, died in Tumakuru. It is not known for certain how he caught the virus. The Karnataka Health Department has posted a notice on Twitter asking whoever travelled with him on train to come forward.

He had no history of recent foreign travel but had apparently traveled to Delhi on March 5 by Sampark Kranti Express and returned on March 11.

On March 7, he arrived at Delhi's Nizamuddin station and participated in an event at Jamia Masjid.

The man took a train back on March 11 and arrived at Yeshwantpur in Bengaluru. From there, he took a bus on March 14 to his hometown Sira.

He first showed symptoms of COVID-19 on March 18 and was taken to a private hospital. He was sent home with medicines but his condition worsened.

On March 23, he was admitted to a district hospital, but checked himself out against all advice and went to a private hospital. When his health showed signs of deterioration, he was again sent to the district hospital, where he tested positive for coronavirus yesterday. He died around 10.30 am today.

The health department has since traced 24 people who came in direct contact with him and are so, in the high-risk category. Thirteen are in hospital and eight have tested negative.

"All passengers who had travelled with him on the train are being traced," K Rakesh Kumar, Deputy Commissioner, Tumakuru, was quoted as telling news agency ANI.

A 70-year old woman and a 76-year old man had died of coronavirus or COVID-19 earlier in Karnataka.

India has over 700 coronavirus cases, including 17 deaths.
