BS Yediyurappa may drop some Lingayat ministers for caste balance

Bengaluru, May 28: The Karnataka government has done away with previously mandatory COVID-19 testing for asymptomatic international travellers. 

The development comes a day after the government issued a circular, which allowed placing of international travellers into home quarantine if they had completed seven days of institutional quarantine.

A circular signed by Jawaid Akhtar, Additional Chief Secretary to the State Government, dated May 27, says that any “person who has completed seven days of institutional quarantine and is asymptomatic can be permitted for home quarantine with a COVID-19 test (RT-PCR), subject to undergoing a medical check-up.”

This check-up equates to thermal screening (with a required temperature of under 37.5C or 99.5F and pulse oximetry of under 94%). 

The circular added that all elderly people, over the age of 60, and those with comorbidities (such as Diabetes mellitus, hypertension, asthma, heart ailment, renal disease...etc) are “required to be clinically evaluated diligently prior to shifting them for quarantine.”

On Wednesday, Pankaj Pandey, Commissioner, the Department of Health and Family Welfare said that these new guidelines were based on recommendations from the COVID Task Force. A member of the COVID Task Force said that new strategies had been formulated based on the latest findings on how the SARS-Cov-2 virus affects people.

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, Jun 12: Karnataka Medical Education Minister K Sudhakar on Friday said experts have indicated a surge in coronavirus cases in the state after August 15 and the government was taking all precautionary measures in that direction. Speaking to reporters in Ballari, Sudhakar said, "About 97 percent of over 3,000 active cases in the state are asymptomatic.

Experts after studying the developments in other countries and states have said that there will be a surge in infections after August 15."

He said the government was taking all precautionary measures in that direction.

 As of June 11 evening, cumulatively 6,245 COVID-19 positive cases have been confirmed in the state, which includes 72 deaths and 2,976 discharges, the health department's bulletin said.

It said, out of 3,195 active cases, 3,185 patients are in isolation at designated hospitals and are stable, while 10 are in ICU.

Meanwhile, in a tweet pointing out that nearly 60 per cent of the COVID cases in the country are from 10 cities, Sudhakar said, despite being the fourth most populous city in the country Bengaluru has been successful in containing its spread.

"Nearly 60% of total COVID-19 cases in India are found in 10 cities. Despite being 4th most populous, Bengaluru has been successful in containing spread of virus.

I urge people to keep up the fight, continue vigil & together with #CoronaWarriors we can defeat the virus," Sudhakar tweeted.

Bengaluru that does not figure in the list of 10 cities shared by the Minister has reported 581 coronavirus cases till last evening, out of which 258 are active.
