Anant kumar Hegde’s convoy accident: Probe ordered

Kasaragod, June 2: As Kerala commenced fresh academic year with online classes from Monday, a ninth-standard student at Malappuram district in North Kerala ended life allegedly owing to lack of online study facilities like television connection and a smartphone at her house.

Devika, daughter of Balakrishnan, hailing from a Dalit community at Valancherry, about 25 kilometres from Malappuram town, ended her life.

Balakrishnan told the media that he could not recharge the television connection owing to financial crunches. He was working as a daily wage worker and owing to COVID-19 and lockdown, he was not having much work these days. 

The family also did not have a smartphone or computer. The family members alleged that Devika was quite upset as she could not attend the virtual class that began on Monday. She was a student of a nearby government school.

Local police said that Devika, who was the eldest among four children of Balakrishnan, was suspected to have self-immolated using kerosene at a premise close to her house on Monday evening. The cause and provocations were still being probed only. No suicide notes were recovered yet.

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.
