We won't allow division of religion: Amit Shah

Bengaluru, May 7: A 55-year old woman from Davanagere became the 30th COVID-19 related fatality in Karnataka, where a total number of infections has crossed 700-mark, with eight new positive cases being confirmed, the health department said on Thursday.

The deceased woman was a known case of diabetes and hypertension, she was admitted with a complaint of Severe Acute Respiratory Infection (SARI) and was on a ventilator, the department said in its mid-day situation update.

She died today at a designated hospital in Davanagere, it said.

"Eight new positive cases have been reported from last evening to this noon...

Till date 701 COVID-19 positive cases have been confirmed. This includes 30 deaths and 363 discharges," the update said.

The eight new cases reported include three from Davangere, indulging the deceased patient; also three from Kalaburagi, and one each from Hirebagewadi in Belagavi district and Bengaluru urban.

While four cases are contacts of patients earlier tested positive, three are with the history of Influenza-Like Illness (ILI) and one is a SARI case.

Five among eight new cases are women and three are men.

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.

Mangaluru, Jun 11: City police on Thursday filed a 700-page chargesheet in connection with the arrest of Aditya Rao, 36, accused of planting an IED at Mangaluru International Airport on January 20.

The chargesheet said the bag placed near MIA entrance had a real bomb, as per the FSL report. The IED in the tin box was made of sulphur, ammonium nitrate, potassium chlorate and charcoal.

Rao, an engineer, who learnt bomb-making through online videos, had also placed a timer along with it and sharp objects such as nails and metals. However, he had not fixed wires to trigger a blast. “His intention was not to cause a blast but only to create a scare,” said sources.

The bomb was made in less than two weeks. However, it had taken Rao several days to procure raw materials. Police had completed the chargesheet process in April.
