IS link suspicion: Kasargod youth who arrived from UAE held at Airport

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.

Udupi, Jun 28: A student appearing for the Secondary School Leaving Certificate (SSLC) exams in Kaup taluk of Udupi district has tested positive for the novel coronavirus (COVID-19) infection.

Officials of the Department of Public Instruction (DPI) and Udupi District Health and Family Welfare Department have confirmed the report. 

The 16-year-old girl had appeared for the Kannada and Mathematics exams on June 25 and 27 respectively. 

Her throat swabs were sent for testing on June 27 after her father tested covid-19 positive. Today she too obtained positive report.  

The student is unlikely to appear for the science paper on June 29.

Meanwhile, health officers have ruled out the possibility of subjecting other students to covid-19 test as all necessary precautions such as physical distancing and usage of sanitization were taken in the examination centre.

Udupi, Jun 9: A Mesolithic site has been discovered at Iduru-Kunjadi in Kundapura taluk of Udupi district of Karnataka by Prof T Murugeshi, Associate Professor of Ancient History and Archaeology at MSRS College, Shirva.

Prof Murugeshi said on Tuesday that the site is near a rock art site of the Mesolithic period that was unearthed. It is located in the Mookambika Wildlife Reserve Forest. At Iduru-Kunjadi, the finds of Mesolithic tools are characterised by blades, scrapers, burine, fluted cores, arrow-heads and flakes of the non-geometric pattern.

He said that though the site was found two years back, it took time to study and identify them. They resembled the tools found in a stratified context at Uppinangady on the Netravati basin, he added.
