APD to monitor air quality in Mangaluru during Diwali

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.

Kasaragod, May 27: In a tragic incident, two persons, who were brothers, died of asphyxiation while trying to rescue a calf that fell in their well at Bandhiyod near here on Wednesday.

Police sources said the elder brother Narayanan (50) entered into the well first to save the calf that fell in the well early in the morning.

His brother Sankaran (40) also followed suit after he noticed his brother fainting deep down the well. However, he also fainted inside the well.

Bengaluru, May 5: The movement of migrant labourers from Karnataka to other states has stopped temporarily, as few North Indian states are yet to give consent.

Revenue Minister R Ashok said that the state government will convince labourers to stay back and ensure free food supply at their camps. "Even if we allow them to travel, they will be quarantined for 14 days as soon as they reach their native states.

The labourers don't know about this and some states have not yet given permission for their return," Revenue Minister R Ashok said.

According to sources in CMO, the decision to convince the workers to stay back came after several major projects - both government and private - were affected by the mass migration of labourers to their native districts and states.

Ashok, along with S Suresh Kumar, Primary and Secondary Education minister and head of the group of ministers focusing on migrant workers, also visited labourers who had gathered demanding that they be allowed to return.

Chief Minister BS Yediyurappa will chair a meeting tomorrow and instruct builders under CREDAI to pay pending wages of labourers, provide food supply and ensure their safety, Ashok said, adding that all construction work by BBMP will also be taken up to help the labourers.
