Stalker' drags college girl out of bus, stabs her to death as people watch

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.

The United States of America has bought almost the entire world's supply of remdesivir, one of just two drugs proven to treat COVID-19. 

“President Trump has struck an amazing deal to ensure Americans have access to the first authorised therapeutic for Covid-19,” said the US health and human services secretary, Alex Azar. 

“To the extent possible, we want to ensure that any American patient who needs remdesivir can get it. The Trump administration is doing everything in our power to learn more about life-saving therapeutics for Covid-19 and secure access to these options for the American people.”

The announcement implies that no other country in the world will be able to buy remdesivir for next three months at least.

The anti-viral drug patented by the US-based Gilead biotech firm is the only one approved by the European Medicines Agency (EMA) to treat patients with the novel coronavirus.

The Trump administration has already shown that it is prepared to outbid and outmanoeuvre all other countries to secure the medical supplies it needs for the US.

“They’ve got access to most of the drug supply [of remdesivir], so there’s nothing for Europe,” said Dr Andrew Hill, senior visiting research fellow at Liverpool University.

Remdesivir, the first drug approved by licensing authorities in the US to treat Covid-19, is made by Gilead and has been shown to help people recover faster from the disease. 

The first 140,000 doses, supplied to drug trials around the world, have been used up. The Trump administration has now bought more than 500,000 doses, which is all of Gilead’s production for July and 90% of August and September.

Bengaluru, Jun 24: Karnataka Chief Minister BS Yediyurappa was all praise for a sixth standard student from Kallianpur in Udupi district for joining the fight against COVID-19 by stitching Face Masks with one hand for SSLC students writing examination beginning from Thursday.
