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, Feb 1: “1) Take necessary precautionary measures. 2) Don’t blindly believe in social media rumours.” These are the two important advisories issued by the authorities in Dakshina Kannada district in the wake of coronavirus scare.

According to DHO Dr Ramakrishna there is no specific antiviral treatment recommended for coronavirus infection. Supportive care for infected people can be highly effective, but, there is no vaccine available for coronavirus.

In a health meeting, he advised people to take precautionary measures to prevent the spread of the virus. Following are some of the precautionary measures.

1) Wash your hands often with soap and water or an alcohol-based sanitiser.

2) Avoid touching your eyes, nose and mouth with unwashed hands.

3) Avoid close contact with people who are sick.

4) Stay home when you are sick, and cover your mouth when you cough or use a tissue while sneezing.

5) Throw the used tissue in the dustbin. Clean and disinfect surfaces frequently.

Deputy commissioner Sindhu B Rupesh said there is no need for people to panic about coronavirus.

Dakshina Kannada zilla panchayat CEO R Selvamani said IEC programmes will be held to create awareness on possibilities of spread of diseases.

He also advised people not to follow blindly the advisories being shared on social media, especially WhatsApp without proper verification.

“Posts on cures for coronavirus which are not scientifically proven are being shared on social media. Do not follow such advisories without verifying facts,” he said.

Bengaluru, Jun 11: Within hours after claiming that it has decided to prohibit schools from schools from conducting online classes till Class 7, the Karnataka government has taken a U-turn and said that currently than ban is only till Class 5.

“Karnataka Govt has decided to stop all online classes for LKG, UKG & classes up to 5th std. To extend this up to 7th std is only a suggestion from few cabinet ministers as expressed in an informal discussion and NOT a decision,” tweeted Prime and Secondary Minister Suresh Kumar.

Law Minister J C Madhuswamy earlier today had stated that the decision to ban online classes till 7th standard was taken by the government.  "All of us were of the opinion that there were challenges faced by students studying in rural areas. Hence, we urged the government to extend the ban on online classes till 7 standard," he said
