Mangaluru: K MC Manipal lifts Medi Quiz 2019 trophy

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.

Mangaluru, June 28: Three fresh deaths in last 24 hours have taken the total number of covid-19 deaths in Dakshina Kannada district to 13.

The woman from Jokatte was reportedly suffering from tuberculosis. On June 26, she was admitted to a private hospital in the city, where she was tested coronavirus positive.

As per the district health bulletin on Saturday June 27 evening, a total of 12,919 samples have been sent for tests till date, out of which 12,198 have turned out negative, and 576 positive, including 10 persons from other districts.

Bengaluru, Apr 10: Renowned ophthalmologist and Narayana Nethralaya Chairman Dr K Bhujang Shetty today advised those wearing contact lenses to switch to eyeglasses as a preventive measure.

“Though the facial mask is mandatory as a preventive measure against the dreaded Coronavirus, not many know that the virus can also enter the body through eyes. Wearing glasses or spectacles reduces the spread of the virus,” Dr Bhujang Shetty said.

Although it is more likely that people may catch Coronavirus infections through mouth and nose, there are chances of the virus also entering through eyes. “In a day, humans tend to touch their face and eyes almost 20 times an hour knowingly or unknowingly. Users of contact lenses end up touching their eyes and face frequently, increasing the risk of infections. Therefore, it is advisable that they switch to eyeglasses until the situation improves”, according to a release here on Friday.
