ASHAs hold protest across Karnataka demanding PPE kits, salary hike

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, Jun 23: Karnataka Medical Education Minister K Sudhakar's wife and daughter have tested positive for COVID-19, a day after his father was confirmed to have been infected with the virus.

"Test results of our family members have come. Unfortunately, my wife and daughter have tested positive for #Covid19 and are undergoing treatment," the minister tweeted on Tuesday.

He said he and his two sons have tested negative.

Sudhakar's father P N Keshava Reddy tested positive for coronavirus on Monday. He was admitted to the hospital with a cough and fever.

Earlier, the domestic help of the minister had tested coronavirus positive and was admitted to a hospital.

In April, Sudhakar was quarantined along with three other ministers for coming in contact with a journalist who was coronavirus positive.

Karnataka reported 249 new COVID-19 cases and five deaths on Monday taking the total number of cases in the state to 9,399 and the death toll to 142.

Test results of our family members have come. Unfortunately, my wife and daughter have tested positive for #Covid19 and are undergoing treatment. My two sons and myself have tested negative. I am grateful to everyone for their best wishes and prayers.
