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, Mar 25 : Karnataka recorded its highest single-day tally to date, as 10 people tested positive, taking the total number of cases to 51 in the state.

“Till date 51 COVID-19 positive cases have been confirmed in the state which includes one death and three discharged," the health department said in a statement on Wednesday.

The rise in cases adding to the growing national tally of people who have tested positive for COVID-19.

The daughter of a former union minister from the Bharatiya Janata Party (BJP) from Karnataka has also tested positive.

Bengaluru accounts for 32 of the total 51 cases recorded in the state so far,including three who have fully recovered and released.

Dakshina Kannada has five confirmed cases, Chikkaballapura and Kalaburagi has three cases each, Mysuru has and Uttara Kannada has two cases each and four other districts have one case each.

Prime Minister Narendra Modi has announced a 21-day lockdown of the country to keep people indoors and contain the spread of the virus in the community.

The government has also been trying to scale up testing.

Medical education minister K.Sudhakar on Wednesday told Mint that Karnataka will scale up testing by 10-fold with the help of government and private labs approved by the Indian Council of Medical Research (ICMR).

A total of 2,438 people have been tested in Karnataka and 2242 have tested negative, according to state health department. 214 people are lodged in medical hospitals.
