12-year-old girl dies after consuming poison in dance class

Bengaluru, Apr 16: With two more people testing positive for COVID-19 in Karnataka, the state's corona cases count has reached 279, including 80 discharged and 12 deaths, said the government on Wednesday.

A total of 19 corona cases were confirmed in the state on Wednesday. 17 cases were reported earlier in the day, of which 15 are male patients and two are female. Of the 17 cases, nine are workers of a pharmaceutical company in Mysuru, the government stated.

Meanwhile, a 65-year-old from Chikkaballapur, who had tested positive for COVID-19, lost his life this afternoon.

"He was referred to a Bengaluru hospital with complaints of H1N1 positive, chronic obstructive pulmonary disease with obstructive sleep apnea and a past history of diabetes and hypertension," the government said.

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.
