[EX Q]: Paragraph: In 2004, a virulent form of canine influenza surfaced at greyhound racing parks in Florida. In that outbreak, it infected 24 greyhounds and killed 8 more. The contagion has since been confirmed in seven states, having killed greyhounds at tracks in Florida, Massachusetts, Arizona, West Virginia, Wisconsin, Texas and Iowa. It is highly contagious, spreading through shared items (like toys) or human contact (kennel workers have carried the virus home with them), in addition to dog-to-dog encounters. The virus that has been felling greyhounds is an H3N8 flu closely related to an equine flu strain. It is not related to typical human flus or to the H5N1 avian flu that killed about 100 people in Asia. Several states — including Florida, Minnesota, and Louisiana, among others — reported another rash of cases in late June 2017. According to the American Veterinary Medical Association (AVMA), the outbreaks in those states were caused by a strain known as canine H3N2 influenza, which was first reported in Chicago in 2015. An AVMA spokesperson, Sharon Granskog, told us in a phone interview that such outbreaks can be seasonal in nature: There’s a time of year when more dogs are in contact with one another, they’re at dog parks, it’s highly contagious. We suggest that you make sure if your dog is going to a dog park that it’s healthy and talk to a veterinarian about whether or not a vaccine would be right for your dog. The disease was first reported in the U.S. in 2004 after several racing greyhounds in Florida contracted it. The AVMA said that they believed that the dogs became infected by a strain of H3N8 influenza, which is particular to horses. Dr. Ruben Donis, chief of molecular genetics for the influenza branch of the Centers for Disease Control and Prevention, confirmed that the flu jumped from horses to dogs, “a very rare event of considerable scientific interest” and added “at this point, there is no reason to panic.” How that jump occurred is either not known at this point or is not being commented on, so the email’s assertion that the eating of raw meat was to blame should be regarded as speculation rather than as fact. While there is always the possibility the virus might again jump species, this time to humans, this strain of flu has been present in horses for more than 40 years without any documented cases of humans catching it or the related canine flu. But there are vaccines available for both the equine and canine flus. Many readers have been confused (and unnecessarily frightened) by the difference between the terms “morbidity rate” and “mortality rate.” The morbidity rate describes the percentage of animals that will contract the disease after being exposed to the virus, but, despite its name, the term has nothing to do with the death rate associated with the flu. (Nearly 80 percent of dogs exposed to the canine flu virus will contract only a mild form of the disease which mimics kennel cough, a type of canine bronchitis that is rarely serious.) The mortality rate, which describes the percentage of animals that will die after contracting the disease, is in the much lower range of 5 to 8 percent, according to Dr. Cynda Crawford, the veterinary immunologist who first isolated the canine flu virus: The mortality rate is around 5 to 8 percent, says veterinarian Cynda Crawford at the University of Florida’s College of Veterinary Medicine in Gainesville. “I want to stress that despite the rumors that are out on the Internet and other such sources, this disease is not as deadly as people want to make it,” Crawford said. She says she receives more than 30 calls a day from concerned veterinarians. Dr. Crawford describes the contagion as producing in dogs “a moist, productive cough that ends in a gagging response, that will persist for one to four weeks, despite treatment with antibiotics or cough suppressants. Some dogs develop a thick, yellow discharge from the nose. A very few dogs will spike a high fever, between 105 to 107 degrees Fahrenheit. They become lethargic and weak, with rapid, shallow breathing. This is likely to progress to pneumonia.” Other veterinary experts have estimated the potential death rate as between 1 and 10 percent, with the higher percentage applying to very young, very old, or infirm dogs. Presence of the virus in dogs can be confirmed only through blood tests performed at the Cornell University College of Veterinary Medicine. Results of such blood screens take as long as two weeks. Dr. Crawford recommends keeping dogs showing symptoms of respiratory disease at home and away from other dogs for up to two weeks. The CDC, which is tracking the disease, issued no official recommendations. Because the symptoms of this as yet unnamed virus somewhat mimic bordetella, a less virulent illness commonly known as kennel cough, it is hard to ascertain how widespread the flu has become. On the flipside of that confusion, vets in various parts of the country have been thrown into a panic when encountering run-of-the-mill kennel cough in any of their clients, fearing they are instead confronting cases of the new flu. The Animal Health Diagnostic Center at Cornell University inserted a caution against such hair-trigger diagnosis within a larger advisory about the potential for the flu to have spread to the state of New York: “One should not lose sight of the fact that all respiratory infections in dogs are not due to canine influenza virus. Adhering to the ‘band wagon’ approach could result in the failure to appropriately treat dogs with infections previously known to cause respiratory problems in dogs.” We found this good advice for vets and dog owners in our inbox one day: PLEASE DO NOT PANIC, and do NOT assume that every cough is Canine Influenza. Kennel Cough from parainfluenza and Bordetella is more common. However, the Animal Health Diagnostic Center at Cornell is interested in receiving samples from dogs that appear to have kennel cough. Clinical Signs: Since this is a new pathogen in dogs, there is currently no natural immunity present in the unexposed canine population. Almost all exposed dogs will become infected, and nearly 80% have clinical signs. In the mild form the dogs will have a cough that persists for 10 to 21 days. The cough may be soft and moist or dry. Many dogs will have a nasal discharge from a secondary bacterial infection and low grade fever. The nasal discharge responds to broad spectrum antibiotics. In the severe form with pneumonia there is a high fever (104-106 F) and respiratory difficulties. X-rays may show consolidation. These dogs often have secondary bacterial infections and have responded to broad-spectrum antibiotics and supportive care including intravenous hydration. The incubation period is two to five days and dogs may shed virus for seven to 10 days. The disease can spread rapidly throughout a boarding kennel. Dogs that are coughing SHOULD NOT BE BROUGHT TO SHOWS or Performance EVENTS. In a 1 June 2017 advisory to its members, the AVMA suggested that vaccines against the H3N2 virus strain “might be another prevention option” for dogs who were at least 8 weeks old and also recommended isolating dogs who could be infected, as well as not sharing toys between dogs and disinfecting shelter, veterinary, and boarding facilities. Claim: A virus deadly to dogs has been spreading in the canine population of the U.S.

[EX Q]: Paragraph: Use of such pills, which include Sanofi SA’s Ambien and other similar drugs, was significantly higher for those in their 50s as well as age 80 and older, according to the findings from the Centers for Disease Control and Prevention. Overall about 8.6 million people, or 4 percent of U.S. adults reported recently using sleep medication, CDC’s National Center for Health Statistics said in a report. But data showed higher use among middle-aged adults ages 50 to 59 and the elderly. Six percent of those ages 50 to 59 said they had taken a prescription sleep pill in the last 30 days, and 7 percent of those age 80 and older reported such use. In between, the numbers dip slightly below 6 percent for those in their 60s and 70s. In comparison, just 2 percent of those aged 20-39 said they had recently taken a sleep aid. CDC researcher Yinong Chong said people in their 50s could have trouble sleeping because of work and family stress. “It gives the picture of a sandwiched group who has family, not only children but also probably elderly parents but still you’re likely to be in the workforce, so you get squeezed at both ends in terms of family responsibility and job responsibility,” she said. Sleep may improve when people retire before potential chronic health problems kick in and begin interfering with sleep, Chong said, adding more study is needed. The data also showed that 5 percent of women surveyed said they had recently taken a sleep aid compared to about 3 percent of male respondents, according to CDC’s report. Chong said it was not clear why women were more likely to use the drugs. While previous data have tracked prescriptions dispensed for sleep aids, the CDC said its study is the first based on a survey of actual use of such drugs. Researchers for the Atlanta-based health agency’s National Center for Health Statistics questioned a sampling of adults age 20 and older about whether they had used prescription sleep aids within the last 30 days and asked participants to show interviewers the prescription medication. “You get how many people are actually using them,” Chong said in an interview, noting that prescription data could include multiple prescriptions for one patient or prescriptions that are never filled or even used. “This is actual use.”  Prescription sleep aids have become somewhat controversial because their effect can linger even after some patients wake up. The U.S. Food and Drug Administration has begun taking a closer look at sleep drugs, ordering lower-doses for Ambien and similar pills amid concerns that their active ingredient remained in patients’ blood the following morning at levels high enough to make driving and other activities dangerous. And just last month, the FDA rejected an experimental sleep drug from Merck & Co Inc, saying the proposed doses were not safe but that a lower-dose version might be acceptable. Not surprisingly, respondents to CDC’s study who said they slept five hours or less each night or those diagnosed with a sleep disorder were more likely to report using prescription aids. Additionally, more whites and people with higher levels of education also reported greater use, the agency said. Socioeconomic factors are likely behind those numbers, Chong said, since patients must be able to afford a doctor’s care and the medication. According to prescription data from IMS Health, Ambien and other versions of the drug zolpidem was ranked 15th among the most dispensed medications in the United States. Claim: Use of sleeping pills highest among older Americans: CDC.
[EX A]: Older U.S. adults, particularly women, are more likely to use prescription sleep medications to try to get the minimum seven hours of sleep experts generally recommend, U.S. data released on Thursday showed.

[EX Q]: Paragraph: The zoo said Tuesday that 9-year-old Jiao Qing was examined last week by experts at the city’s Leibniz Institute for Zoo and Wildlife Research after the discrepancy was picked up on an ultrasound. The 110-kilogram (243-pound) bear underwent the scan while under anesthesia. Doctors confirmed one kidney is smaller. The panda’s urine will be tested to determine whether the smaller kidney is functioning properly. Even if not, animals can live healthy lives with only one kidney. Jiao Qing is the father of twin cubs born Aug. 31. They are doing well. Claim: Grin and bear it: Berlin panda gets CT scan for kidney exam.
[EX A]:
A Berlin zoo says a giant panda whose twin cubs have captured international attention has undergone a CT scan after veterinarians discovered one of his kidneys was smaller than the other.
