BJP has nothing to do with the Congress MLAs resignation: BSY

Bengaluru, May 23: The Karnataka government on Friday said returnees from six states with high COVID-19 cases will be kept in institutional quarantine for seven days.

The states are - Maharashtra, Gujarat, Delhi, Tamil Nadu, Rajasthan and Madhya Pradesh.

As per the standard operating procedure released by the government, all people to arrive via rain, air road are expected to quarantine.

After they test negative for the disease in pool testing, they will be sent for home quarantine for another seven days, the government said.

Returnees from other low prevalence states will be asked to follow 14 days of home quarantine, according to the standard operating procedure (SOP) for entry of persons from other states to Karnataka issued by the state health department late on Friday night.

However home quarantine is allowed for pregnant ladies, people above 80 years, patients with comorbidities and children below 10 years of age, along with one attendant after they test negative.

In special cases like businessmen coming for urgent work, the quarantine period will be waived if they furnish a report from an ICMR-approved laboratory showing they tested negative for COVID-19, it said.

However, if they don't have reports, they will have to stay in institutional quarantine and can leave once their results test negative.

In case their stay exceeds 5 days, they will be sent to the fever clinic and get a five-day extension if found asymptomatic.

The report should not be more than two days old from the date of travel.

All Karnataka returnees who entered from 4 May will be tested from 5-7 days from the time of their arrival.

If found COVID-19 negative, they will be sent to home quarantine and will have to follow due precautions, the SOP stated.

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.
