[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: Scientists at Vienna University medical school’s Institute of Hygiene and Applied Immunology came to the conclusion after analyzing the water quality at 21 “holy” springs and 18 fonts at churches and chapels at various times of year. Only 14 percent of the water samples from holy sources showed no fecal contamination, and none of the springs could be recommended as a source of drinking water, the study presented to a conference in Vienna this week found. The springs held not only fecal contamination - likely the result of poor hygiene - but many also had agricultural nitrates and bugs that can cause inflammatory diarrhoea. “We need to warn people against drinking from these sources,” microbiologist Alexander Kirschner said in the study. Kirschner said the healing effects ascribed to holy sources arose from the hygienic conditions of the Middle Ages, when water quality in urban areas was generally so poor that people constantly contracted diarrhoea or other conditions. “If they then came across a protected spring in the forest that was not as polluted and drank from it for several days, their symptoms would disappear. So although in those days they were drinking healthier water, given the excellent quality of our drinking water today, the situation is now completely reversed.”  The study noted some ways to help address the problem, including regularly replacing holy water in church fonts. One Italian priest has invented a holy water dispenser that dispenses drops of holy water rather than having the faithful dip a hand in, it noted. Claim: Holy water in Austria unsafe to drink: researchers.
[EX A]: Holy water at religious shrines and churches in Austria is often contaminated with fecal matter and bacteria, researchers have found, advising the faithful not to drink it, especially in hospital chapels.

[EX Q]: Paragraph: The review was requested by the Swedish medicines regulatory agency, which decided in November to amend the product information for Norlevo, which contains levonorgestrel, the European Medicines Agency said. The labeling was changed to say that in clinical trials, contraceptive efficacy was reduced in women weighing 165.34 pounds or more, and levonorgestrel was not effective in women who weighed more than 176.37 pounds. Emergency contraceptives, which contain levonorgestrel or uliprista acetate in the European Union, act by blocking or delaying ovulation. The emergency contraceptives being reviewed include medicines that contain levonorgestrel, such as Norlevo, Levonelle/Postinor and Levodonna, the EMA said. It also includes a centrally-authorised medicine, ellaOne, which contains ulipristal acetate and was granted a marketing authorisation in Europe in 2009. The United States is also reviewing the effect of weight on the efficacy of emergency contraception. Claim: Europe assessing if weight affects 'morning after pill' success.
[EX A]:
European regulators said on Friday they would assess whether emergency contraceptives, known as the “morning after pill” worked as effectively in women weighing more than 165.34 pounds, and whether the warning labels should be changed.
