New research confirms that temperature and symptom checks miss many coronavirus infections. A study published Wednesday found that these measures failed to detect infections in new Marine recruits before they started training, even after several weeks of quarantine. Many recruits had no symptoms yet still spread the virus. The work has implications for colleges, prisons, meatpacking plants and and other places that rely on symptom screening. Doctors say more COVID-19 testing is needed, especially in younger people who often don't develop symptoms.“We spent a lot of time putting measures like that in place and they’re probably not worth the time as we had hoped,” said Jodie Guest, a public health researcher at Atlanta’s Emory University who had no role in the research.“Routine testing seems to be better in this age group” because younger adults often have no symptoms, she said.The study was led by researchers from the Icahn School of Medicine at Mount Sinai in New York and the Naval Medical Research Center.It involved 1,848 Marine recruits, about 90% of them men, who were told to isolate themselves for two weeks at home, then in a supervised military quarantine at a closed college campus, The Citadel in Charleston, South Carolina, for two more weeks. That included having a single roommate, wearing masks, keeping at least 6 feet apart and doing most training outdoors. They also had daily fever and symptom checks.The recruits were tested for coronavirus when they arrived for the military quarantine and 7 and 14 days afterward. Sixteen, or about 1%, tested positive on arrival and only one had any symptoms. Another 35 -- an additional 2% -- tested positive during the two-week military quarantine and only four had symptoms.Only recruits who tested negative at the end of both quarantine periods were allowed to go on to Parris Island for basic training.Genetic testing revealed six separate clusters of cases among the recruits.A separate study published Wednesday in the New England journal reports on an outbreak last spring on the aircraft carrier USS Theodore Roosevelt. Among the crew of 4,779, mostly young people, 1,271 became infected; 77% did not show symptoms when diagnosed and 55% never developed any.The case shows that “young, healthy persons can contribute to community spread of infection, often silently,” Dr. Nelson Michael of the Walter Reed Army Institute of Research wrote in a commentary. 2442

NEW YORK (AP) — As monuments, statues, and memorials around the world come under increased scrutiny, some former Most Valuable Players in Major League Baseball are saying they'd like to see a change in future MVP plaques.The trophy is engraved with the name of Kenesaw Mountain Landis in large letters. Landis was baseball's first commissioner and there were no Black players in the majors during his reign from 1920 until his death in 1944. His name has been on every American League and National League MVP plaque since then. Barry Larkin, Terry Pendleton, and Mike Schmidt say they'd like to see it pulled off. 621

NEW YORK (AP) — New York City police were concerned about Pete Davidson after he wrote "I don't want to be on this earth anymore" on Instagram. And they visited the "Saturday Night Live" star to make sure he was OK.A police spokesman declined to say where officers met with Ariana Grande's ex-fiance on Saturday. But his Instagram posting was deleted and NBC did not cancel its live show.On the show, Davidson introduced a performance of John Lennon's song "Happy Xmas (War is Over)" by musical guests Miley Cyrus, Mark Ronson and Sean Ono Lennon.What alarmed Davidson's fans and authorities was the tone of the entertainer's post: "I'm doing my best to stay here for you but I actually don't know how much longer I can last. All I've ever tried to do was help people. Just remember I told you so." He added a heart emoji.Social media erupted with words of love for the 25-year-old comedian and native New Yorker who first appeared on "Saturday Night Live" in 2014. And his name is trending on Twitter.One admirer tweeted "hang in there. There is a lot of help out here. Surrender to some love ... I'm praying for you Pete. I've been there. It gets better."Earlier this month, Davidson wrote on Instagram that he has spoken about borderline personality disorder from which he says he suffers, "and being suicidal publicly only in the hopes that it will help bring awareness and help kids like myself who don't want to be on this earth."No matter how hard the internet or anyone tries to make me kill myself. I won't. I'm upset I even have to say this."Davidson and Grande were engaged in June, but broke up earlier this fall.In November, Davidson apologized for mocking the appearance of a veteran who lost an eye in Afghanistan.He said Lt. Com. Dan Crenshaw, now a congressman-elect from Texas, "deserves all the respect in the world."On SNL's "Weekend Update" segment , Davidson was joined by Crenshaw, a Navy SEAL.Davidson had mocked Crenshaw a week earlier, saying viewers might be surprised he's "not a hit man in a porno movie."Crenshaw, a Republican who won a House seat in the 2018 midterm elections, took some joking shots at Davidson. And when his cellphone rang, the tone was "Breathin" by Grande.Crenshaw got serious at the end, encouraging civilians and veterans to connect and paying tribute to heroes like Davidson's father, a firefighter who died in the 9/11 terror attacks.If you or a loved one needs help, call 1-800-273-8255. 2453
