Note ban will end up making UP polls more costly: Survey

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, Jul 16: People volunteering as civil police wardens with the city police department will not receive any remuneration, an official said on Wednesday.

“We wish to clarify the rumours floating on social media and confirm that the volunteers helping local police as civil police wardens in enforcement of anti-Covid measures will not be paid any remuneration,” said an official.

On Tuesday, Bengaluru city police commissioner Bhaskar Rao had urged interested people to volunteer for the department, indicating how strained the department has been amid Covid.

“Inviting physically fit and service minded residents of Bengaluru, both men and women, between the age of 18-45 to volunteer as civil police wardens,” said Rao.

The department is offering a choice of the police division, jurisdiction and the shifts one wants to choose to be a civil police warden.

Additional Commissioner of Police Hemant Nimbalkar said volunteers are a welcome support to the police in their field duty but should not be left alone.

“Volunteers are a support to the police in the field and shall not work standalone. They shall be attached with duty police as assistance. A jacket and a cap should be provided to them,” said Nimbalkar.

He reminded that the safety of the volunteers is the responsibility of the policemen.

Many city policemen have been infected with the virus and quarantined while more than six have succumbed.

“It is a tough time for all policemen irrespective of the rank. Four hundred and fifty active cases across the state and the loss of six lives speak volumes about their involvement in the war against Covid,” said Director General of Police Praveen Sood recently.

He expressed hope that the difficult times will pass, saying all the members of the police department are a family.

Tumkur, Jun 2: Karnataka Agriculture Minister BC Patil on Monday said that state will not be affected due to locust swarm as it has moved to other states.

"There will be no effect as locust insects diverted to other states after they came from Pakistan. We were also worried and were prepared to face it, luckily we will not be affected by insects," he said.

Locust is a type of grasshoppers and moves in large numbers and devastates crops. Several parts of Rajasthan including Ganganagar have reported locust attacks.

There is a prediction of another attack in June this year.
