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.
Has a virus deadly to dogs been spreading in the canine population of the U.S.?

Paragraph: The state Department of Environmental Protection is considering new regulations on how much toxins are allowed in the state’s waterways. The Tampa Bay Times reports that environmentalists say the state should set numeric limits on the amount of toxins. However, the state agency believes the new limits should determine when and where to declare a public health emergency, not as a tool to try to prevent such emergencies. Florida had the worst blue-green algae bloom last year in the state’s history. That was coupled with a devastating red tide outbreak along the state’s beaches that caused respiratory irritations in people and killed sea turtles, manatees, dolphins and fish. ___ Information from: Tampa Bay Times (St. Petersburg, Fla.), http://www.tampabay.com. Claim: Environmentalists, state officials disagree on toxin limits.
Environmental activists and state environmental officials disagree about how regulations should be used to combat algae blooms in Florida’s waterways.

Paragraph: Oly Ilunga has overseen Democratic Republic of Congo’s near year-long response to what is the second deadliest Ebola outbreak in history. It has killed more than 1,700 and been declared an international health emergency by the World Health Organization (WHO). President Felix Tshisekedi on Saturday appointed a team led by Jean-Jacques Muyembe, the head of Congo’s biomedical research institute, to coordinate the government’s response in Ilunga’s place. In his resignation letter, the minister criticised pressure by unnamed “actors” to deploy the second vaccine, manufactured by Johnson & Johnson and backed by the WHO. It has yet to be used on the ground due to Ilunga’s objections. It is designed to complement a Merck treatment that has been given to 170,000 people and proved effective. Ilunga has said the J&J vaccine has not been proved effective and that deploying a second one would confuse people in eastern Congo, where health workers are struggling to overcome widespread misinformation about the haemorrhagic fever as well as sporadic hostility. Ilunga said it would be “fanciful to think that the new vaccine proposed by actors who have shown an obvious lack of ethics by voluntarily hiding important information from medical authorities, could have a significant impact on the control of the current outbreak”. J&J says the vaccine has been tested on more than 6,000 volunteers and raised no particular safety concerns. Its chief scientific officer, Paul Stoffels, said in a telephone interview that the company had been “very transparent, very open and in full communication” with Congolese authorities. He said J&J had discussed with Muyembe how people could be vaccinated around eastern Congo’s biggest city, Goma, where a first Ebola case was confirmed last week, to create a protective “curtain”. “Whether they use it or not, it’s fine for us,” said Stoffels, referring to Congolese officials. “They have to judge based on their personal knowledge of how and where to use it.”   The WHO and other international donors including medical charity Medecins Sans Frontieres have publicly supported using the second vaccine, of which 1.5 million doses are available. A WHO spokesman said the organisation was grateful for Ilunga’s leadership and dedication and looked forward to “working closely with the new coordination team as we have with the previous one”. Last week, the organisation labelled the outbreak an international emergency, a rare designation aimed at galvanising global support as it threatens to gain a foothold in neighbouring Rwanda and Uganda. Only the 2013-16 epidemic in West Africa that killed more than 11,000 people has been deadlier. Claim: Congo minister's resignation over Ebola snub could unblock new vaccine.

Congo’s health minister resigned on Monday after being stripped of responsibility for managing the country’s Ebola outbreak, potentially paving the way for the introduction of a second vaccine to contain the spreading epidemic.
