Gowda demands case against CM Yediyurappa in audio-tape case

Bengaluru, May 6: More than a month after international flights have been barred, Karnataka government is preparing to quarantine all 10,823 of the state''s people poised to return home from overseas amid the Covid pandemic, an official said on Tuesday.

"The state has planned to quarantine all 10,823 passengers coming back to Karnataka. The quarantine guidelines framed as below would be applicable," said Health Commissioner Pankaj Kumar Pandey in a statement.

According to the Government of India, 10,823 Karnataka residents have been stranded abroad by April 30, comprising 4,408 tourists, 3,074 students, 2,784 migrants and professionals and 557 ship crew.

Out of the 10,823 people, the state government is expecting 6,100 to return early as the government has decided to allow Indians stuck abroad to return.

"All the passengers arriving at points of entry (airports and seaports) will be compulsorily screened for symptoms of Covid-19," said Pandey.

Point of entry screening will include self-reporting form verification, thermal screening, pulse oximeter reading, briefing with instructions, categorisation, stamping for some and downloading of Aarogya Setu, Quarantine Watch and Apthamitra apps.

Arriving passengers are also required to declare existing comorbidities such hypertension, diabetes, asthma or any lung disease, organ transplantations, cancer, tuberculosis and other ailments.

Passengers will be categorised into three groups: Category A (symptomatic on arrival), Category B (asymptomatic with co-morbidity or aged above 60 years) and Category C (rest of asymptomatic passengers).

Depending on the category into which the people fall, their quarantine place and time will be determined.

Category A arrivals will be subjected to institutional quarantine for a fortnight, Category B one week quarantine at a hotel or hostel, followed by another week at home, and Category C home quarantine for a fortnight.

Karnataka government is making elaborate arrangements and logistical means, deploying healthcare, police and several other departments into action to handle the huge influx of Kannadigas and state residents.

Pandey has issued a 21-page elaborate standard operating procedure (SOP) guidelines on how to face the international returnees.

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.
