Q: Paragraph: The airline had earlier said only cabin crew operating mainland China flights could wear masks, in response to the airline’s flight attendants calling for permission to wear masks on all flights globally as cases have also been confirmed in the United States, Thailand, South Korea, Japan and Taiwan. “Due to the evolving information from health authorities, we will allow crew members and frontline airport employees to wear surgical face masks when on duty at their discretion,” Cathay said in a statement. The coronavirus outbreak, which began in the central Chinese city of Wuhan, struck as millions of Chinese prepared to travel for the Lunar New Year, heightening contagion risks. Wuhan’s local government said it would close all urban transport networks and suspend outgoing flights from the city as of 10 a.m. on Thursday (0200 GMT), state media reported, adding that the government said citizens should not leave the city unless there were special circumstances. The Cathay Pacific Airways Flight Attendants Union said on Tuesday it had received a “tremendous” amount of emails and messages from members concerned over catching the virus given they are exposed to over 300 passengers from numerous places on a single flight. On Wednesday evening, Cathay said on its website that rebooking, rerouting and refund charges would be waived for all tickets booked on or before Jan. 21, arriving to or departing from Wuhan through March 31, an extension from the Feb. 15 date listed the prior evening. Deaths from China’s new flu-like virus rose to 17 on Wednesday, with more than 540 cases confirmed. The virus has already spread beyond Wuhan to population centers including Beijing, Shanghai, Macau and Hong Kong. Cathay said that as required by the Hong Kong health authorities, it was distributing health declaration forms and will be making face masks and antiseptic wipes available at the boarding gate to passengers traveling from Wuhan to Hong Kong. “Our frontline staff are reminded to maintain good personal and environmental hygiene, and to remain alert and vigilant while being on the lookout for passengers presenting with infectious disease symptoms,” the airline said. Cathay has already been hit by plummeting demand as a result of anti-government protests in Hong Kong, leading it to cut capacity and defer the delivery of four planes. Shares in Cathay have fallen by 10% since the start of January as the virus spread. Jefferies analysts said shares in Cathay and mainland Chinese carriers could remain under pressure for some time if the coronavirus situation paralleled the 2003 SARS outbreak and cases continued to increase. That coronavirus outbreak killed nearly 800 people. Claim: Cathay to let crew wear masks on all flights due to new coronavirus.

A: Hong Kong’s Cathay Pacific Airways Ltd (0293.HK) will allow all crew members and frontline employees to wear surgical masks due to concerns over a new coronavirus, and said passengers to and from Wuhan, China, could change or cancel flights for free through March 31.

Q: Paragraph: Such a test could initially be used to select patients for clinical trials of experimental treatments being developed to try to halt progression of Alzheimer’s, the researchers said, and may one day move into routine use in doctors’ clinics. “Alzheimer’s begins to affect the brain many years before patients are diagnosed (and) many of our drug trials fail because by the time patients are given the drugs the brain has already been too severely affected,” said Simon Lovestone of Oxford University, who led this work from King’s College London. “A simple blood test could help us identify patients at a much earlier stage to take part in new trials and hopefully develop treatments,” he said. Alzheimer’s is the most common form of dementia, a brain-wasting disease which in 2010 was estimated to be costing the world $604 billion a year. The fatal disease affects 44 million people worldwide, with the number set to triple by 2050, the campaign group Alzheimer’s Disease International says. Several big pharma firms including Roche, Eli Lilly, Merck & Co and Johnson & Johnson, are pursuing various approaches to get to the root cause of Alzheimer’s and try to find treatments to halt its progression. Yet over the past 15 years, more than 100 experimental Alzheimer’s drugs have failed in trial. Lovestone and other experts believe this may be because drug trials are conducted too late, in patients whose condition has already gone too far. A predictive test for use before people develop symptoms would help researchers select the right people for drug trials, and help show whether the experimental drugs are working. Previous studies have found that PET brain scans and tests of lumbar fluid can be used to predict the onset of dementia from people with a less severe condition known as mild cognitive impairment (MCI), but these tests are expensive and invasive, so scientists are keen to develop a cheaper, simpler blood test. MCI includes problems with day-to-day memory, language and attention. It can be an early sign of dementia, or a symptom of stress or anxiety. Around 10 percent of people diagnosed with MCI develop dementia within a year. Apart from regular assessments to measure memory decline, there is currently no accurate way of predicting who will or won’t develop dementia. For this study, published in the journal Alzheimer’s & Dementia, Lovestone’s team used blood samples from 1,148 people - 476 with Alzheimer’s, 220 with mild cognitive impairment and 452 elderly controls without dementia. They were analyzed for 26 proteins previously found to be linked with Alzheimer’s. The team found 16 of these 26 proteins to be strongly associated with brain shrinkage in either MCI or Alzheimer’s and then ran a second series of tests to see which of these could predict which patients would progress from MCI to Alzheimer’s. With this second series, they found a combination of 10 proteins capable of predicting with 87 percent accuracy whether people with MCI would develop Alzheimer’s disease within a year. Experts in the field welcomed the results but said they should be replicated in larger studies before an Alzheimer’s blood test could be rolled out for use in doctors’ clinics. “The results reported today are interesting, but as the authors point out there is still a very large amount of work remaining until a usable blood test for Alzheimer’s disease becomes available,” said Adrian Pini of the MRC Center for Developmental Neurobiology at King’s College London. James Pickett, head of research at the Alzheimer’s Society, said the research “does not mean that a blood test for dementia is just around the corner”. “These 10 proteins can predict conversion to dementia with less than 90 percent accuracy, meaning one in 10 people would get an incorrect result,” he said. “Accuracy would need to be improved before it could be a useful diagnostic test.” Claim: Study paves the way for a blood test to predict Alzheimer's.

A: British scientists have identified a set of 10 proteins in the blood that can predict the onset of Alzheimer’s and call this an important step towards developing a test for the incurable brain-wasting disease.

Q: Paragraph: "Sunday show talking heads continued to debate vaccinations of children -- specifically, how there should be no debate -- as they analyzed political missteps from the past week. BBC World News America anchor Katherine ""Katty"" Kay made a startling comparison to highlight how Americans have been less diligent in making sure their children are properly immunized. ""There are countries in Africa where they have higher vaccination rates than here in the United States,"" Kay said on NBC’s Meet the Press. ""Because when people really need it, and they see the effects that measles can have on their communities, they will make sure that their children vaccinate."" Rhetoric about the measles outbreak stemming from Disneyland in California, home to a significant measles-resistant population, is keeping PunditFact and PolitiFact busy. We wanted to continue our look at this re-emerging viral threat by examining the accuracy of Kay’s claim. While we did not hear back from her by our deadline, we have a pretty good idea of Kay’s source. The World Health Organization, which recommends infants be vaccinated with at least one dose of the MMR vaccine before their first birthday, maintains immunization rates for the measles vaccine among 1-year-olds by country. The most recent data is for 2013. There were 16 African countries that beat the U.S. rate of 91 percent for the measles-mumps-rubella vaccine in 2013, according to the WHO data. (The Centers for Disease Control and Prevention puts the measles immunization rate in the United States is 91.9 percent. But the WHO and CDC measure the statistic in different ways, and as you'll see, it doesn't make a difference.) The countries besting the United States are Algeria, Botswana, Burundi, Egypt, Eritrea, Gambia, Kenya, Lesotho, Libya, Mauritius, Morocco, Rwanda, Seychelles, Tanzania, Tunisia and Zimbabwe. United States 91 percent * Algeria 95 percent Botswana 94 percent Burundi 98 percent Egypt 96 percent Eritrea 96 percent Gambia 96 percent Kenya 93 percent Lesotho 92 percent Libya 98 percent Mauritius 99 percent Morocco 99 percent Rwanda 97 percent Seychelles 97 percent Tanzania 99 percent Tunisia 94 percent Zimbabwe 93 percent  Of course, many African countries facing steep impoverished conditions have lower and substantially lower rates, such as Central African Republic (25 percent), Chad (59 percent), Equatorial Guinea (42 percent), Ethiopia (62 percent), Nigeria (59 percent), South Sudan (30 percent) and South Africa (66 percent). More broadly, it’s not just African countries beating the United States. Latin American countries with rates about the same as or exceeding the United States’ include El Salvador, Guatemala, Honduras and Mexico. South Africa-based think tank Good Governance Africa spurred news about the United States trailing some African countries in a Feb. 5 press release highlighting the WHO data. Researcher Kate van Niekerk hailed the improved availability and widespread usage of the vaccine as a ""major public health success"" that has reduced child deaths even though the disease continues to kill about 400 children every day. Still, Dr. Cathy Troisi, infectious disease epidemiologist at the University of Texas Health Science Center at Houston School of Public Health, said the nearly universal use of the measles vaccine in some parts of Africa is the result of a large international effort to reduce child mortality. Reducing by two-thirds the under-five mortality rate between 1990 and 2015 was one target of the United Nations millenium goals. Unlike in some regions of Africa, where measles remains a leading cause of child death, some American parents are strangers to scary, eradicated diseases that afflicted prior generations, she said. Americans also generally value individual rights over community needs, she added. ""I’m old enough that I was born before the polio vaccine became available,"" Troisi said, ""and you can bet when it came out, my mom was first in line to get me vaccinated. Part of the reason we’re seeing this refusal is because parents haven’t seen what these diseases can do."" Because we were curious, we wondered how the U.S. vaccination rate stacked up against its more populous companions. The U.S. population is about 319 million, making it the third-most populated country. China, with 1.36 billion people, is at 99 percent. India, with 1.24 billion people, has a rate of 74 percent. Indonesia, at 253 million residents, had a rate of 84 percent. Brazil and its population of more than 200 million residents had a measles vaccination rate of 99 percent. Our ruling Kay said, ""There are countries in Africa where they have higher vaccination rates than here in the United States."" We found ample evidence to back up her point, with several African countries boasting better vaccination rates than the United States. Mauritius, Tanzania and Morocco have nearly complete vaccination of 1-year-olds, according to World Health Organization data." Claim: There are countries in Africa where they have higher vaccination rates than here in the United States.
