California Gov. Gavin Newsom is quarantining with his family after three of his four children were exposed to a patrol officer who tested positive for Covid-19, he said in a tweet late Sunday.

Malaysia will close some factories of the world’s largest maker of latex gloves in stages as it moves to screen employees for Covid-19 after more than 2,000 workers tested positive, authorities said.

Top Glove has racked up record profits this year on sky-rocketing demand for its products and protective gear, thanks to the pandemic.

But 28 factory buildings will be shut in phases after 2,453 workers tested positive for the virus, from 5,767 screened, the country's director-general of health Noor Hisham Abdullah said on Monday. The cases are the country’s largest active cluster and its second largest since the start of the pandemic.

The government put up barbed wire fences in front of the workers’ hostels on Tuesday, with checkpoints that were guarded by police and army personnel. 

Top Glove has around 16,000 employees and runs 47 factories across Malaysia, Thailand, China and Vietnam, with 36 of them producing gloves. Europe and North America are its biggest markets.

Queen Letizia and their two daughters will continue their royal activities, the source said.

The boss of Australia’s largest airline said Monday that once a coronavirus vaccine becomes widely available, it may require passengers to use it before they can travel abroad.

Qantas Chief Executive Alan Joyce said he’s been talking to his counterparts at other airlines around the world about the possibility of a “vaccination passport” for overseas travelers.

“We are looking at changing the terms and conditions to say for international travelers that we will ask people to have the vaccination before they get on the aircraft,” Joyce told Australia’s Network Nine television.

Australia has imposed some of the most severe border restrictions in the world since the pandemic began, closing its borders to most international visitors. The country has weathered the pandemic, with nearly 28,000 cases and just over 900 deaths since pandemic began, fewer than many other nations of its size.

Players in the National Football League must wear masks on the sidelines unless they have their helmet on and are preparing to enter the game, the league said Monday as it unveiled an enhanced set of Covid-19 protocols.

In a memo distributed to teams, the NFL also outlined increased safety regulations for play-callers and said post-game interactions between players and staff would be limited.

Players that failed to comply would be subject to discipline, the league said.

The league added that the maximum number of players permitted to travel to road games would be reduced to 62 and access to club facilities would be limited for non-essential personnel. All members of a team's traveling party must wear N95 or KN95 masks on team planes and buses, it said.

HELENA, Mont. — The Montana governor’s office says more than 100 contracted medical staff have arrived in the state to assist hospitals in responding to the spike in COVID-19 cases.

The 110 health care workers are part of an anticipated total of 200 to be deployed in the state before Thanksgiving and who will remain until the end of the year.

The workers, including registered nurses and respiratory therapists, will aid hospitals that are at or near capacity as part of a contract between the state and NuWest, which provides traveling health care workers.

U.S. Sen. Kelly Loeffler, R-Georgia, has tested negative for Covid-19 after a second PCR test, her campaign said Monday.

Loeffler, who is in a competitive runoff race that could determine the balance of power in Congress, had been quarantining after Covid-19 tests in which some tests were negative, another PCR test was positive and another test was inconclusive.

Monday night Loeffler "received her second consecutive negative PCR test result," campaign spokesperson Stephen Lawson said in a statement. Lawson said Loeffler has no symptoms and feels great. "She looks forward to getting back out on the campaign trail," the statement says.

PCR stands for polymerase chain reaction, and the tests are considered highly accurate but take longer than some other tests.

Colorado's governor on Monday signed an executive order that allows the state health department to order hospitals to stop admitting patients or transfer patients to other facilities.

The executive order granting the authorization to the Colorado Department of Public Health and Environment lasts for 30 days.

The order says that given the rise in Covid-19 cases, the number of people seeking treatment may far exceed capacity and hospitals may need to transfer patients. NBC affiliate KUSA of Denver reports that it gives the state department flexibility and that hospitals in the state have already shown a willingness to transfer patients from one that is overburdened to another facility.

There have been more than 202,000 cases of Covid-19 in Colorado, with more than 2,400 deaths, according to state data.
