Dr Zakir Naik files defamation case against 10 media houses

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, May 26: Karnataka chief minister BS Yediyurappa has been urged to cancel the proposed SSLC examinations in Karnataka and allow “mass-pass” for every student in the wake of covid-19 crisis. A group of intellectuals and educationists have put forth this demand.

In the letter released by educationist VP Niranjan Aradhya, said that they were listing the scientific reasons to the CM for cancellation of exams which are slated to be held from June 25 to July 4th.

In the letter, the intellectuals have elucidated a number of reasons for cancelling the upcoming exams. “There are close to 8.5 lakh students and 2.5 lakh staff involved. If we include parents who would drop their kids at the exam centre, around 30 lakh people will be involved in the process, making it a risky affair. Though the government has said that it will separate the students with fever or other ailments, will students admit to having fever? What if they consume paracetamol and come to write exams?” asks the letter. 

Added to this, the question papers have to be sent from the district and taluk centres and there may be chances of transmission.

“Even if we conduct exams, then what about the students who have failed? Every year, around 2.5 lakh students fail in the exam. Will the government conduct the supplementary exams again? The whole process of conducting exams comes at a huge cost of Rs 20 cr to Rs 25 crore. Hence, we are suggesting that the government cancels the exams and pass the entire group of student en masse,” said the letter.

Bengaluru, Mar 3: Karnataka Health Minister B Sriramulu has said that a medical team is monitoring the health condition of all those people who had stayed with the coronavirus-hit techie who is admitted to a hospital in Hyderabad.

The first confirmed case of the novel coronavirus (COVID-19) in Telangana was reported from Hyderabad on Monday where a man from Bengaluru, who recently returned from Dubai, tested positive for the virus.

"It has come to our knowledge that the coronavirus-hit person in Hyderabad had gone from Bengaluru. Therefore, all the members in the house where he had stayed here have been identified and are under watch," Mr Sriramulu tweeted on late Monday night.

The minister said he has convened a meeting with the additional chief secretary, commissioner and other senior officials of the health department today.

"Our government has initiated all the measures to prevent the spread of this virus," the minister said.

It is learnt that the 24-year-old techie had not contracted it when he was in Bengaluru but all precautionary measures have been taken.

The software engineer, who works in Bengaluru, had worked with people from Hong Kong in Dubai last month where he is suspected to have contracted the virus, Telangana health minister E Rajender told reporters in Hyderabad.

The man reached Bengaluru on February 19/20 and later went to Hyderabad in a bus.

He took treatment for fever after coming to Hyderabad and was admitted to a private super speciality hospital in the city. As it did not subside, he came to the state-run Gandhi hospital on Sunday evening, Mr Rajender said.
