Shocking: No passport for PM's wife, as she has no marriage certificate

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, Jun 8: Facing a shortage of labour, some top builders in the city have initiated efforts to bring back the migrant workers, who have returned to their native places following the COVID-19 lockdown, and are holding parleys with Railway authorities for operation of special trains to ferry them.

After the lockdown was announced, many construction projects came to a halt and accordingly the labourers were rendered jobless. These migrant workers preferred to go back to their home state as they were not paid when the projects were stopped and were caught in the big financial mess. Many of these migrants even chose to cover thousands of kilometres by foot when even trains, buses or any motor vehicles were not operating.

Keeping their woes in view, the Centre decided to run the Shramik Special trains to ferry them to their native places. But, after they were gone, the builders found themselves in a lurch. An executive of a builder told PTI "Yes, our builder and a few others are in talks with the Railways to run the special train to bring back the labourers." She said nothing has been materialised as of now.

According to her, the builders took the contact numbers of the workers when they left the city to their home states and are now contacting them one by one. The South Western Railway has so far sent 3.11 lakh migrant workers in 216 Shramik Special trains starting from May 3 to June 6.
