Will not allow Hindu temples in Pakistan to be destroyed: Hafiz Saeed

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, Mar 10: Three more positive COVID-19 cases have been confirmed in Karnataka taking the tally to four, state Health Minister B Sriramulu on Tuesday informed.

"Their family members have been isolated and their health is being monitored. I urge citizens to take precautionary measures and co-operate in preventing the spread of this infection," Sriramulu said.

As on Monday, the national tally of persons affected by the coronavirus is 45.

According to the Indian Council of Medical Research (ICMR), in the past 24 hours, one positive case from Kerala, two from Pune, and three from Bengaluru have been confirmed.

Apart from the ICMR; National Institute of Virology in Pune; 51 Virus Research and Diagnostic Laboratories; and National Centre for Disease Control, New Delhi are carrying out tests for COVID-19.

Bengaluru, May 18: Indian food delivery startup Swiggy said on Monday it would lay off 1,100 employees, or nearly 14% of its workforce, to cut costs, as a weeks-long nationwide lockdown to curb the coronavirus outbreak hits demand for online food ordering.

The company, backed by South African internet giant Naspers, also said it will scale down adjacent businesses and has already shut several of its cloud kitchens - facilities that only cater to takeaway orders - temporarily or permanently.

“The core food delivery business has been severely impacted and will stay impacted over the short term, but is expected to start growing again after that,” said Sriharsha Majety, co-founder and chief executive at Bengaluru-based Swiggy.

Swiggy, one of India’s best known startups, is among many that are laying off employees and reshaping their business in response to the COVID-19 pandemic, which has forced 1.3 billion Indians indoors and crippled business.

India is currently under a two-month lockdown, and though several curbs are being eased, public places such as restaurants remain closed, hurting restaurants themselves as well as companies such as Swiggy and main rival Zomato.
