When traveling to many places, it’s required to quarantine or get tested for COVID-19 before and after you arrive.Starting Thursday, Iceland is going to let visitors skip all of that if they prove they've had COVID-19 and recovered. But for now, travel from the U.S. to the country still isn't allowed.So, are these so-called immunity passports a good idea?Dr. Ania Wajnberg at Mount Sinai has been studying COVID-19 antibodies since March. Her team has tested more than 80,000 people in the New York area, and they’ve found the majority of people who had COVID-19 form moderate or high levels of antibodies.“Since March and April, almost everybody has maintained their level of antibodies. We do see a slight decrease, but overall, they've maintained their antibody levels,” said Wajnberg.But it's not entirely clear how long immunity does last and how good the protection against COVID-19 is.Wajnberg says we also don't have a lot of data on whether people who have antibodies could still possibly carry enough of the virus that they could spread it.The World Health Organization has advised against immunity passports. It says there's not enough evidence of immunity from antibodies alone.“I think given that we know that many or most people likely have some protection, this is not an unreasonable way to begin to open up society in a safer way than just throwing open the doors and hoping for the best,” said Wajnberg.Iceland's chief epidemiologist says he doesn't think it's fair to people who've had COVID-19, that they shouldn't be allowed to travel freely afterward.Critics of immunity passports warn they could potentially reward reckless people who become infected after ignoring COVID-19 rules or take away more of our medical privacy. 1755

We've all heard exercise helps you live longer. But a new study goes one step further, finding that a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease.Dr. Wael Jaber, a cardiologist at the Cleveland Clinic and senior author of the study, called the results "extremely surprising.""Being unfit on a treadmill or in an exercise stress test has a worse prognosis, as far as death, than being hypertensive, being diabetic or being a current smoker," Jaber told CNN. "We've never seen something as pronounced as this and as objective as this."Jaber said researchers must now convey the risks to the general population that "being unfit should be considered as strong of a risk factor as hypertension, diabetes and smoking -- if not stronger than all of them." 799

With his pledge to save a major Chinese company from crippling US sanctions, President Donald Trump has delivered yet another twist in the trade clash with Beijing.His announcement on Twitter that he's working to give China's ZTE "a way to get back into business, fast" was a sudden shift in the US stance at the start of a big week for trade ties between the world's top two economies.Washington and Beijing have threatened to impose tariffs on tens of billions of dollars of each other's products, fueling fears of a full-blown trade war.Talks in Beijing earlier this month aimed at dialing down the tensions failed to produce any major breakthroughs. But Chinese President Xi Jinping's top economic adviser is heading to Washington this week for more negotiations. American companies will also have a chance to publicly tell the Trump administration what they think about its planned tariffs on Chinese goods.Here's what to keep an eye on this week. 960

With coronavirus cases ramping up in a number of US states, more and more US governors have issued mandates to wear masks while in public settings.The continued spike in COVID-19 cases has caused several states to close bars and pause plans to reopen some businesses such as movie theaters.While a number of states had previously mandated masks in many public spaces, several more have been added to the list in recent days. Requiring face coverings are largely being seen as a way to avoid reinstituting stay-at-home orders, which most states implemented during the spring.Researchers from the University of Washington say that a projected 33,000 American lives would be saved between June 23 and October 1 if 95% of the population wore masks in public settings.A study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.The following states generally require face coverings to be worn in public:Alabama - July 16Arkansas - July 16California – June 18Colorado - July 17Connecticut – April 20Delaware – May 1District of Columbia – May 16Hawaii - April 17Illinois – April 30Indiana - July 27Kansas - July 3Kentucky - July 10Louisiana - July 13Maine – April 29Maryland – April 18Massachusetts – May 6Michigan - April 24Minnesota - July 25Montana - July 16Nevada – June 24New Jersey - April 10New Mexico – May 15New York – April 15North Carolina – June 26Ohio - July 23Oregon - July 1Pennsylvania – April 18Puerto Rico Rhode Island – May 8Texas - July 2Vermont - August 1Virginia - June 8Washington - June 26West Virginia - July 7Some states, like Ohio and Texas, require mask wearing only in counties where there are high coronavirus case rates. More than a dozen other states have issued recommendations for wearing masks. Some of those states require employees in certain fields to wear a mask while at work. 2059

When you think of police officers, you may think of the badge or the local precinct may come to mind, but a lasso?“You got to have a lasso in a small town,” Sgt. Jace Peterson said with a laugh.Sgt. Peterson says it is an item he never leaves home without. Home is Nephi, Utah and it has been most of his life.“Oh, I was a good kid who got in very little trouble,” Peterson said.Nephi is a "blink and you miss it" stop along Interstate-15 between Salt Lake City and Las Vegas.Sgt. Peterson is just one of 10 full-time officers.“I just patrol all the corners of town, backstreets and the main thoroughfares,” he said.A disorderly conduct call sometimes comes in the form of a farm animal.“We’ve had cows and goats,” Peterson said. “I mean you name it and they run loose around here.”Sgt. Peterson knows he is just one call away from a surprise class reunion.“It makes it entertaining when you stop somebody you know or you’re on a call with somebody you went to high school with,” he said.Life moves at a slower pace in these parts. It is a stark contrast from what officers in major cities across the country are dealing with.“The rioting and the protest,” Sgt. Peterson said slowly shaking his head. “I mean, it starts to wear on you a little bit and know that other officers aren’t as lucky as we are.”The Nephi Chief of Police echoes those sentiments.“You know, the great thing is I had the big city policing experience when I was young,” said Chief Mike Morgan. “When I was young, I could get out and do the things that needed to get done and I was able to learn; that experience brought me here.”Like Peterson, Chief Morgan has come home.“There’s no place like home,” Chief Morgan said with a chuckle.The move from big city life means big changes.“There are no protests at all down here,” Chief Morgan said.The department is prepared for the day some of the bigger city issues may creep into town.“We’ve got all the equipment I could ever ask for and it’s such a great community,” Sgt. Peterson said.Even a worldwide pandemic is not affecting the small-town police force much.“I mean, we know it’s there and we know it’s just one bad day away, but until then, we’re just going to sort of enjoy it,” Sgt. Peterson said. 2231
