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.

Karwar, Jun 3: The India Meteorological Department (IMD) has issued an alert, predicting thundershowers and heavy rainfall over north interior Karnataka, coastal Dakshina Kannada and Udupi over the next three days.

With Cyclone Nisarga hitting the Uttara Kannada coast on Tuesday,  parts of coastal Karnataka received heavy rainfall. Gusty winds tore through the coastal towns, as the sea too turned violent with rough waves smashing the shore.

The alert was issued with the advancement of Nisarga from east-central Arabian Sea to north Maharashtra, and adjoining south Gujarat coast. “Though it does not cover Karnataka, the range of cyclonic winds is very big and reaches north interior Karnataka also.

So an alert has been called out,” CS Patil, director in-charge, IMD, Bengaluru, said. The weather department has forecast a severe cyclonic storm and then a depression. Patil said formation of systems is a common factor before the onset of the monsoon and they help in its advancement.

“Cyclone Nisarga is helping in the quick advancement of the southwest monsoon to Karnataka, and the monsoon is likely to arrive before the scheduled date as conditions are favourable,” he added.

Bengaluru, Jul 15: Karnataka Pradesh Congress Committee President D K Shivakumar on Tuesday alleged Chief Minister B S Yediyurappa led state government of corruption and said it had not spared even beds and pillows meant for COVID-19 patients to make "corrupt" money.

Taking to microblogging site Twitter, Congress leader said BJP government will be exposed in the coming days.

"It is nauseating that @BSYBJP govt has not even spared the beds and pillows meant for CoVid patients to make corrupt money from. There are many such scams involving ministers. Evidences about them will be placed before people and the BJP Govt will be exposed in the coming days," he tweeted.

Cabinet minister Jagadish Shettar on Monday announced a complete lockdown in Karnataka's Dharwad area from 10 am on July 15 to 8 pm on July 24 in a bid to control the rising number of COVID-19 cases.

According to the State's health department, Karnataka has a total of 41,581 positive cases so far, including 24,572 active cases and 16,248 recoveries.

So far, 757 people have lost their lives to coronavirus in the State.
