[EX Q]: Paragraph: Three of the other five patients are in either a serious or a critical condition in hospital, while the remaining two have mild symptoms, the United Nations health agency said in a disease outbreak update. H7N9 bird flu emerged last year in China and has infected around 150 people so far there and in Taiwan and Hong Kong, killing at least 46 of them. The latest death was a 38-year-old man from China’s Fujian Province who became ill with H7N9 on January 3, was admitted to hospital on January 8 but died 2 days later. He had underlying illnesses, including tuberculosis and pneumoconiosis. China’s state news agency Xinhua reported another death from H7N9 in the southwestern Guizhou province on Monday, but this has yet to be confirmed by the WHO. A 65-year-old man infected with H7N9 also died in Hong Kong, the government said on Monday. The WHO reiterated there is no evidence as yet of any easy or sustained person-to-person transmission of the strain, and that the source of the human infections is still under investigation. Researchers in the United States said last month that while it is not impossible that H7N9 could become easily transmissible between people, it would need to undergo multiple mutations to do that. Scientists around the world are keeping a watchful eye, on alert for any sign the virus might develop that potential and start to spread rapidly. Claim: Death toll from new China bird flu rises: WHO.
[EX A]: Six more people in China have been confirmed as infected with the new H7N9 strain of bird flu and one of them has died, the World Health Organisation (WHO) said on Monday.

[EX Q]: Paragraph: The article did not discuss costs. Screening mammograms impose a significant cost on the U.S. health care system and insurers, particularly Medicare. The story detailed the relative harms of earlier mammograms, but did not translate those percentages into absolute numbers. For instance, women who were diagnosed with breast cancer 25 months or more after their last mammogram were “50 percent more likely” to need chemotherapy, “32 percent more likely” to need mastectomy, and “66 percent more likely” to need lymph nodes removed. However, relative risk can be misleading, sometimes inflating numbers to sound scarier than when absolute numbers are used. Also, we don’t know what kind of risk these women had at baseline, so it’s hard to know if they were higher risk. The story made no mention of the harms of earlier or more frequent screening, which have been documented time and time again. More screening can mean more false positives or more finding of breast changes that lead to more testing, such as biopsies, more costs, and more worry. The story did make clear some of the weaknesses of the study: The study found an association but did not prove causality and the study population was limited to a single health care institution. The story also mentions that the findings were presented at a meeting, which means they have not undergone peer-review. The story does not directly engage in fear-mongering. However, some of the quotes advocating for earlier and more frequent screening play into a scenario that breast cancer is lurking in every woman. A discussion of what a woman’s average lifetime risk is would have been helpful. The story quotes the study author and an outside source. The story makes clear that different advisory groups have differing guidelines for what age to start getting mammograms (40 or 50 years old). It would have been nice if the story had included examples of what makes someone higher risk or not (personal cancer history, family history, history of radiation), but we think this was satisfactory. We believe that mammograms are well-known to be widely available. And the earlier and more frequent screening described here is not earlier or more frequent than what many guidelines recommend, so would not be expected to be denied by health insurers. The story makes clear the distinctive aspects of this study —using avoidance of more aggressive treatment regimens as a deciding factor, as opposed to the more extreme avoidance of cancer death. The story goes beyond what was contained in a news release on the presentation at the American Society of Breast Surgeons annual meeting. Claim: Earlier Mammograms May Mean Less Need for Aggressive Treatments
[EX A]: This HealthDay news story reports on findings among women diagnosed with breast cancer: those who had longer intervals between mammograms end up getting more aggressive treatments, including chemotherapy and surgery. The story would have been stronger had it described the findings using absolute rather than relative numbers. But, we were glad to see an independent source offer some reservations about the small observational study raised. A final note — the image accompanying the story was laughably unrealistic. Mammograms are the primary screening method for detecting breast cancer. However, when to start getting mammograms and how often to get screened have been subjects of controversy for the past decade. That’s because the data on how to balance risk of developing breast cancer and the risk of harms from screening (unnecessary tests and procedures) are interpreted differently by doctors and other experts. A story that adds new data to the field and that might tip current guidelines one way or the other is newsworthy.

[EX 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.
[EX 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.
