BSF jawan shoots dead 3 colleagues, kills self

Thiruvananthapuram, Jun 10: The man who fled from the Medical College Hospital where he was undergoing treatment for COVID-19 committed suicide on Wednesday morning after being brought back. He used his bed sheet to hang himself from the ceiling.

Hailing from Anad near Nedumangadu, the man, who was undergoing treatment in the isolation room set up at KHRWS pay ward, escaped from the hospital and boarded two KSRTC buses to reach his home.

The Health Department had said the latest tests had returned negative and he was to be discharged on Wednesday. However, City Police Commissioner Balram Kumar Upadhyay had claimed that one more test result of the person was awaited.

The man was blocked by locals upon his arrival at Anad. He was later taken back to the hospital and the police had registered a case against him under the Kerala Public Health Act and Epidemic Diseases Ordinance.

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.
