Degree colleges to reopen in Karnataka after lockdown is lifted: DyCM

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.

New Delhi, Jun 11: The Department of Pharmaceuticals has given its nod for lifting of ban on the export of hydroxychloroquine, Union Minister D V Sadananda Gowda said on Wednesday.

India had banned export of hydroxychloroquine on March 25, with some exceptions, amid views in some quarters that the drug could be used to fight COVID-19. On April 4, it completely banned the exports without any exception.

"Department of Pharmaceuticals has approved the lifting of ban on export of Hydroxychloroquine API as well as formulations. Manufacturers except SEZ/EOU Units have to supply 20 per cent production in the domestic market," the minister of chemicals and fertilisers said in a tweet.

The Directorate General of Foreign Trade (DGFT) has been asked to issue formal notification in this regard, he added.

In another tweet, Gowda said he held discussions with representatives of pharma companies along with some of his ministerial colleagues on the challenges being faced by the industry and on the roadmap to boost exports.

"Had detailed discussion with representatives of pharma companies & association, stakeholder Ministries along with Hon Ministers @piyushGoyal  ji, @HardeepSPuri  ji, & @MansukhMandviya  ji on entire gamut of challenges faced by the industry as well as strategies to boost pharma export," Gowda tweeted.

India exported hydroxychloroquine API (active pharmaceutical ingredient) worth USD 1.22 billion in April-January 2019-20.

During the same period, exports of formulations made from hydroxychloroquine was at USD 5.50 billion.

Bengaluru, Feb 7: Karnataka's Directorate of Health and Family Welfare Services on Thursday issued guidelines for testing, isolation, hospital admission and discharge in view of the outbreak of Novel Coronavirus (nCoV) in Wuhan city of China, a virus that has infected nearly 20,000 globally and has killed more than 500 in China.

According to the guidelines, the sample of any passenger, whether symptomatic or asymptomatic, with a history of travel to or residence in Wuhan city of China in the last 14 days, has to be collected and tested.

And the sample of any health personnel, who develops symptoms of the virus after being associated with the infected persons, has to be collected.

The circular further says that the clinical sample of any suspect/probable case of nCoV will be sent to the laboratory confirmation and the case will be kept in isolation. If tested positive, the treatment has to be provided as per the existing guidelines.

The virus originated from Wuhan, a Chinese city, in December and has since then spread to various parts around the world.

China has imposed quarantine and travel restrictions, affecting the movement of 56 million people in more than a dozen cities, amid fears that the transmission rate will accelerate.
