Question: Paragraph: Sweeping testing for the coronavirus among the entire crew of the Roosevelt has already yielded a curious result: The majority of the positive cases so far are among sailors who are asymptomatic. With so many of the crew symptom-free, it is unclear how many of them had been infected and recovered without anyone realizing they had contracted the virus. Many of these infections could have finished their cycle before testing of the crew began. The extent of the infections aboard the vessel should become more clear with results of the new “outbreak investigation” the Navy announced that will use serology testing developed by the U.S. Centers for Disease Control and Prevention (CDC). The serology tests look for the presence of specific antibodies that are created by the immune system’s attack response to the presence of the virus and remain in the blood for a period of time. “We are seeking crew member volunteers,” Navy Surgeon General Rear Admiral Bruce Gillingham told reporters. The roughly thousand volunteers who are being sought for testing over the next week or so will also be swabbed again for COVID-19, the respiratory disease caused by the virus, as well as asked to answer a short survey, officials said. The U.S. coronavirus death toll - the highest in the world - surged past 35,000 on Friday. It also claimed the life of a sailor from the Theodore Roosevelt this week. The Navy’s testing of the entire 4,800-member crew of the aircraft carrier - which is about 94% complete - was an extraordinary move in a case that already has led to the firing of the ship’s captain and the resignation of the Navy’s top civilian official. It has also given scientific researchers a case study about how the virus spreads asymptomatically in a confined environment among mostly younger adults. That cohort has been somewhat underrepresented in the epidemiological data so far. As of Friday, some 660 sailors - nearly 14% of the crew - had tested positive for the coronavirus. The Navy has said that about 60% of those positive tests were among sailors who were symptom-free. The Navy said medical staff on the island of Guam, where the ship pulled into port, would take the samples and collect questionnaire results. The actual serology tests will be sent to the CDC in Atlanta for analysis. The data could further shed light on how the coronavirus spreads undetected, which could help inform the U.S. national response to the pandemic and efforts to restart the economy. “We will also be sharing that with the White House task force so that that information can be used for the benefit of the nation,” Gillingham said. Claim: U.S. to start antibody testing of sailors on coronavirus-hit aircraft carrier.

Answer: The U.S. Navy said on Friday it will conduct antibody testing of sailors aboard the coronavirus-hit aircraft carrier Theodore Roosevelt to determine whether they were exposed to the virus as it spread through the ship.


Question: Paragraph: There is also the revival of the humble foam roller, which experts say, like old-time push-ups, squats and planks, has never been more popular. Anita Golden, fitness manager at a Crunch gym in New York City, said she’ll be giving clients a foam roller called the GRID. “We’ve always had foam rollers in the club but now more people are using them as a way to ease post-workout muscles, prevent injuries and exercise the core,” Golden said. When it comes to big-ticket items, Colleen Logan of Icon Health and Fitness, which manufactures a number of fitness brands, said the treadmill remains the most popular gift. “Treadmills continue to lead the industry in terms of home fitness purchases,” said Logan. They account for about 57 percent of fitness purchases, while elliptical trainers and stationary bicycles are a distant second and third place at about 8 percent each. The average home treadmill costs about $700, said Logan, but the technology revolution has transformed even this stalwart at the high end. The ultimate splurge, at $4,000, she said, is the Boston Marathon Treadmill, which allows users to adjust speed in 1/10 of a mile per hour increments without touching the console. It also lets users run a virtual Boston Marathon. For people on a smaller budget, there is the iFit app that lets the iPhone capture a favorite vacation run or bike ride in Hawaii, store it in data centers all over the world which collectively are referred to as the “cloud,” and download it to an iFit-enabled treadmill at home. “You’ll view the exact route and experience the same terrain again,” Logan explained. Devices, gadgets and apps proliferate as tech-savvy fitness becomes more accessible, according to Jessica Matthews of the American Council on Exercise (ACE). “There’s a lot of interest in on-body monitoring devices as ways to motivate and track progress,” she said. “They run the gamut from basic devices to track hours, steps, and caloric expenditure to full-body tracking.”  Nike+ Sportsband has a series of small lights on the wrist band that change from red to green as the runner nears his goal, while the BodyMedia FIT Armband tracks everything from the number of calories burned to the quality and quantity of sleep. ACE also studied fitness DVDs released for the holidays. “We evaluated them for quality of instruction, safety, effectiveness and design of workout,” Matthews said. Among the best were “Amy Dixon’s Breathless Body Vol.2: The Edge.” Matthews called it a challenging cardio workout best suited to those on your list with “an established base of fitness.”  “Jessica Smith’s 10 Pounds Down Better Body Blast” also got a thumbs up for its well-rounded routine and clarity of instruction. For people seeking a mind-body approach, Matthews praised “STOTT Pilates Intense Body Blast: Pilates Interval Training: Level I,” which she said is accessible for someone new to fitness. “They do a great job queuing movements and creating flow,” she said. Richard Cotton of the American College of Sports Medicine suggests giving the fitness novice the gift of a personal trainer. “The best is human assistance,” he said. “Another way is a beginner group exercise class.”  He also suggests a gift certificate for shoes at a running store equipped with a treadmill. “You need shoes that fit your gait,” he said. “People should always get their gait analyzed.”  Golden likes to cite the law of reciprocity to the personal trainers she manages. “I always tell them to get their clients something,” she said. And what does the personal trainer want for Christmas? “I like the roller, or a new jump rope,” she said. “Fitness people aren’t hard to please. Get me a new yoga mat and I’m happy.” Claim: Holiday fitness gifts trend from high-tech to basic.

Answer: Looking for the perfect holiday present for a fitness fan? Gift offerings this year range from apps that can store a run in the country to be viewed later to gadgets so sophisticated they measure quality of sleep as well as calories burned.


Question: Paragraph: In a report issued Thursday, the U.N. health agency said the number of measles cases from January to June this year is double the number reported for the same period in 2018. Measles is among the world’s most infectious diseases and is spread mostly by coughing, sneezing and close personal contact. Although numerous European countries have introduced stronger vaccination policies, stubborn pockets of vaccine refusal have fueled epidemics across the continent. Last month, the German government proposed making measles immunization mandatory for children and employees at kindergartens and schools; there have been more than 400 cases of measles in Germany this year. With more than 84,000 cases, Ukraine accounted for the vast majority of measles in Europe, followed by Kazakhstan and Georgia. In February, Ukraine’s health ministry said eight people had died of measles. An expert WHO committee said four countries — Albania, the Czech Republic, Greece and the U.K. — have now lost their status as having eliminated measles. Measles is preventable with two doses of the vaccine, but there is no effective treatment once people are infected. “If high immunization coverage is not achieved and sustained in every community, both children and adults will suffer unnecessarily and some will tragically die,” said Dr. Guenter Pfaff, chair of a WHO expert committee on measles in Europe. In some developed countries, measles vaccination rates dropped sharply following the publication of a flawed study in the late 1990s that linked the combined measles, mumps and rubella vaccine to autism. Health officials have struggled to debunk misperceptions about the vaccine’s safety ever since. “Misinformation about vaccines is as contagious and dangerous as the diseases it helps to spread,” WHO Director-General Tedros Adhanom Ghebreyesus in a statement this week. In 2017, WHO estimated about 110,000 people died from measles worldwide, mostly children under 5-years-old. Claim: ‘Dramatic resurgence’ of measles seen in Europe, WHO reports.

Answer:
The World Health Organization says there has been a “dramatic resurgence” of measles in Europe, in part fueled by vaccine refusals, with nearly 90,000 people sickened by the virus in the first half of 2019.
