Expats advised to carry re-entry visa printouts

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.

Mysuru, Mar 3: Three leopard cubs were rescued by a team of Forest Department in Mysuru on Tuesday.

The cubs were found in a sugarcane field and came into notice of a farmer while cutting the sugarcane.

The villagers alerted the forest department which rescued the three cubs.

In a shocking incident, a pharmacist-cum-production manager of an Ayurvedic product company in Chennai’s T.Nagar died after drinking a chemical preparation he reportedly formulated for tackling the Coronavirus.

The managing director of the company, who is an ophthamologist by qualification, was hospitalised after he fainted soon after he ingested the chemical component.

The deceased, K.Sivanesan, 47, of Perungudi, was with Chennai-based Sujatha Biotech, an Ayurvedic and herbal products company which was founded 30 years ago. It has a plant in Kashipur, Uttarakhand, where Sivanesan was working. Sivanesan had devised formulas of various products and used to visit his managing director Dr. Rajkumar frequently in the city.

Due to the lockdown, Sivanesan came to Chennai and stayed with his family in Perungudi. On Thursday morning, he procured the chemical component from a market in Parry’s Corner.

First he gave a small amount powder he derived from the chemical to 67 years-old Rajkumar who fainted after tasting it.

Even as he was being resuscitated, Sivanesan went into the kitchen of the house and gulped it in liquid form after adding water to it. He could not be revived.

Deputy Commissioner of Police, T.Nagar, Ashok Kumar, said, “Our investigation revealed that Sivanesan died after drinking the preparation he claimed would help COVID-19 patients. His managing director fainted after tasting it initially. Further investigation is on.”

Sivanesan was rushed to a private hospital in T.Nagar and declared dead by the doctors there. Later his body was shifted to Government Royapettah Hospital for post-mortem. Teynampet police registered a case under section 174 of Criminal Procedure Code for unnatural death.

N.S.Vasan, designer-cum-media manager of the company said, “Due to the lockdown, Sivanesan stayed in the city and one day told us he heard of some medicine from U.S. President Donald Trump’s recent speech for curing Coronavirus. He said it would bring more immunity and help to prevent COVID-19. Deciding to test the effect of the medicine, he went to Parry’s Corner and bought the powder.” He added that Sivanesan must have taken a heavy dosage of the ‘drug’ and he was killed instantly.
