[Q]: 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.

[Q]: Preliminary results found the bacteria in the water supply at a prison medical facility in Stockton and at two neighboring youth correctional facilities, Corrections Department spokeswoman Vicky Waters said. Officials had thought it was isolated to one housing unit where the two inmates lived. They restricted water use throughout the medical facility and neighboring juvenile facility, bringing in bottled water. But they put special filters only on showers in the housing unit where the inmates had been housed in the California Health Care Facility, which treats about 2,670 inmates needing medical or mental health care. The neighboring O.H. Close Youth Correctional Facility houses about 150 youths and N.A. Chaderjian Youth Correctional Facility about 260 youths. No subsequent illnesses were reported and the source hasn’t been found. But officials now are adding the shower filters in other areas and warning against using unfiltered water throughout the three facilities. “We are responding to preliminary findings and recommendations,” Waters said in an email. “We are still awaiting the final findings and working on a remediation plan.” That includes deciding how they will clean out the bacteria from the facilities’ water system and how much it might cost, she said. The bacteria weren’t detected in the Stockton city water supply, though the city supplies water to the state facilities. An inmate who died last month had Legionnaires’ disease, which is considered a severe form of pneumonia. A second inmate tested positive for the bacteria but is in good condition. Legionella bacteria grow in water and spread through water vapor. They can cause a mild infection known as Pontiac fever or the more serious infection known as Legionnaires’ disease, according to the federal Centers for Disease Control and Prevention. The disease occurs when contaminated water is inhaled into the lungs. It is considered particularly dangerous for older people and those with underlying health issues. Officials tested 28 inmates who suffered from pneumonia in February or March, but only the two inmates tested positive, officials said. Tests are pending on a more recent inmate with pneumonia. No inmates died but nearly 80 were sickened during a 2015 outbreak at San Quentin State Prison, 80 miles to the west. That temporarily forced the state’s oldest prison to cancel visits, hot meals and showers and ship in water and portable toilets.

[Q]: In the early 1990s, 43 percent of U.S. homes were smoke-free, a figure that rose to 83 percent in 2010-2011, according to the study, issued by the Centers for Disease Control and Prevention. More than 90 percent of homes without a smoker and nearly half of those with at least one adult smoker had smoke-free rules, the study said. “It’s a shift in social norms,” said Brian King, lead author of the CDC study. “People no longer see smoking around non-smokers as socially acceptable behavior.”  Still, he said, more progress is needed, particularly in homes where smokers live, as secondhand smoke from cigarettes kills an estimated 41,000 non-smokers annually. “We know there is no safe level of secondhand smoke,” King said. “The ultimate goal is to not expose people to a known carcinogen.”  The increased number of smoke-free homes is attributable in part to the diminishing segment of Americans who smoke. Some 18 percent of Americans were smokers in 2012, down from 42 percent in 1965, the CDC said. With smoking bans increasingly common at bars, restaurants and in private workplaces, homes are the primary source of secondhand smoke for children and non-smokers, the CDC said. Roughly half of U.S. residents are now covered by laws that ban smoking in public places, the agency said. Smoking bans are now expanding to apartments, public housing and even to cars with children inside, King said. Among states, the percentage of smoke-free homes ranged from a low of 69.4 percent in Kentucky and West Virginia to 93.6% in Utah during 2010–2011, the CDC said. The study did not ask respondents to specify whether they were referring to tobacco or marijuana smoke in the home, the CDC said.
