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.

Mangaluru, Apr 23: The scarcity of water in Kukkavu area of Belthangady town in Dakshina Kannada district has forced school-going children to dig a well with their hands.
The children studying in primary schools were seen lifting the heavy buckets of water from the well.

The residents were facing the water shortage from the past couple of days, amid the coronavirus lockdown.
A group of five adolescents managed to dug the well as deep as 12 feet within just a span of four days.

" We are facing water problem now. With the support of my five more friends, we dug this well. At the beginning we just found soil, then in the deeper layers, we also found stones. We got access to the water at 10 feet down," said Dhanush, a class 9th student, while speaking to news agency.

The shortage of water during the summer months is a perennial problem in across several states in India, and the growing population has only added to the woes.

In extreme conditions, poor have to draw water from small water holes.

Bengaluru, Mar 4: With details of the Bengaluru links of the Covid-19-positive patient from Hyderabad emerging, state health authorities on Tuesday got down to tracking any infection trail he may have left behind before heading home.

Schools from southeast Bengaluru asked parents to send students with masks and hand sanitizers or keep them at home if they had fever. Medical shops in Bengaluru reported panic buying of masks and hand sanitizers.

Two persons with no symptoms — the Hyderabad man’s flatmate in city, and a colleague — reported at Rajiv Gandhi Institute of Chest Diseases and put under watch at the isolation ward. Their test results are expected on Wednesday.

The authorities tracked down 71 people who had come in contact with the Hyderabad man and put them under surveillance. The 24-year-old techie had travelled to Dubai for work on February 15 and returned to Bengaluru on February 20. He attended work on February 20 and 21 before taking a bus to Hyderabad. His flat has been sealed for sanitizing.

According to Telangana officials, at least 36 of the 88 people who came in contact with the techie are showing some symptoms of Covid-19.

Contrary to reports, the infected person was not tested at the KIA since guidelines don’t say flyers from Dubai must be screened. WHO guidelines say identification of the infected person should not be revealed. However, WhatsApp groups were flooded with messages on where the infected person lived and details of his flatmate.
