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 19: To better enforce social distancing and prevent further spread of Covid-19, the Karnataka health and family welfare department on Wednesday said it will "stamp the back of the palm" of international passengers advised to be on home quarantine, along with the date they are allowed to get out of home. The stamping process began at 12am Thursday.

Pankaj Kumar Pandey, commissioner, health and family welfare, said: "It is noted that a few passengers under home quarantine are not following the instructions. Therefore, it has been decided to stamp the back of the palm of their left hand with a specially designed stamp which will indicate the last day of quarantine."

He said the special stamp will use an indelible ink and "airports in Karnataka have been instructed to follow this without fail". On average, about 3,000 people are arriving in Bengaluru on international flights every day.

The department said social distancing is the only known method of combating the spread of Covid-19 and added, "International passengers are segregated as symptomatic and asymptomatic."

High-risk flyers kept at mass quarantine unit

The symptomatic passengers (Group-A) are taken to designated hospitals; asymptomatic ones, depending on the port of origin, are taken to the quarantine centre or permitted to go on home quarantine.

At the mass quarantine centre, the asymptomatic passengers are divided into moderate-risk (Group-B) and high-risk (Group-C) categories.

“The high-risk passengers are kept at a mass quarantine centre for medical observation. The moderate-risk passengers are being sent for home quarantine where they need to spend 14 days,” the statement added.

Pandey said: “International passengers changing flights within the country cannot be stopped. Ideally, they should be stamped at the first port of entry when they arrive from a foreign country which is not happening.” He said this issue will be brought to the notice of the Directorate-General of Civil Aviation.

Mangaluru, Jul 22: Institute of Medical Sciences and Research Centre, within the metropolis, has obtained approval from the Indian Council of Medical Research (ICMR) for testing SARS-CoV-2 virus by Real Time RT-PCR technique.

This has given a lift to the prevailing Covid-19 testing services in Dakshina Kannada, according to a press release by the AJ Institute here on Wednesday.

Institute Dean stated that devoted kiosk for pattern assortment has been opened in the hospital. Staff and technicians from the Department of Microbiology have undergone coaching in molecular testing at NIMHANS, Bengaluru.
