FYI: INFLUENZA, CANINE - USA: (TEXAS) ********************************
Date: 17 Sep 2011 Source: My San Antonio.com [edited] <http://www.mysanantonio.com/community/article/Dog-flu-cases-reported-in-San-Antonio-2174695.php> 20 confirmed cases of canine influenza and 70 suspected cases have been recorded in San Antonio dogs within the past 30 days, according to a local veterinarian. The disease, also known as dog flu, has also been reported in Austin and Dallas, said Dr. Michele Wright, who helped identify the virus at a local clinic. According to the Centers for Disease Control and Prevention, Texas is one of 38 states where dogs have been exposed to the H3N8 virus. The 1st San Antonio case originated with 2 dogs that stopped at dog day care centers and parks, both community sites where dogs could have contracted the disease, Wright said. Signs include a fever, runny nose and coughing, but some dogs infected with the virus do not show symptoms. The virus is not transmitted to humans, cats or other species. Wright said dogs shed, or transmit, the virus through secretions that expose it to the environment. "What's scary for me as a veterinarian is they can act and look healthy and still be shedding the virus," Wright said. Two tests can confirm the virus. The vaccine is available at veterinarian offices. According to the CDC, the virus was 1st detected in 2004 in greyhounds. Scientists believe it jumped species from horses to dogs and adapted to cause sickness and spread among dogs. Wright said because many local dogs haven't been vaccinated, close to 100 percent would get the virus if exposed. 20 percent would transmit it but not appear sick. 72 percent would show mild signs of coughing that could linger for 2 to 3 weeks, and 8 percent could develop pneumonia that could be life threatening. Animal Care Services director Gary Hendel said ACS has not confirmed any cases of canine influenza in the shelter. "It's a situation that bears watching," Hendel said. "Should that situation change, we will work with our local veterinary community to identify solutions to prevent widespread outbreak." Wright suggested that pet owners vaccinate their dogs; limit visits to communal areas to prevent exposure, and keep dogs away from contaminated areas for a month after immunization, to build up immunity. "I think if we can get people vaccinating, we'll be able to contain the virus," Wright said. "The hard thing is getting people to vaccinate in areas that haven't seen it yet." Dog flu is a contagious respiratory disease in dogs caused by a specific Type A influenza virus known as canine influenza virus. It is not a human influenza virus, and people cannot get it. The virus can be spread to other dogs by direct contact with respiratory secretions from infected dogs, by contact with contaminated objects, and by people moving between infected and uninfected dogs. Nearly all dogs are susceptible to infection, but most will have a mild form of the disease. Clinical signs are cough, runny nose and fever; a small proportion of dogs can develop severe disease, characterized by the onset of pneumonia. Testing to confirm flu virus infection is done at veterinary centers. An approved vaccine is available. [Byline: Vincent T. Davis <[email protected]>] -- Communicated by: ProMED-mail from HealthMap alerts <[email protected]> [Canine influenza is a type A orthomyxovirus. It mimics "kennel cough" or _Bordetella brochiseptica_/parainfluenza virus complex, which sounds like a hacking cough that does not seem to stop. The cough with canine influenza can be either moist or dry, and about 20 percent of infected dogs may show little or no clinical signs but still be shedding virus. Canine influenza is contagious by aerosolized droplets and contaminated fomites (inanimate objects) that the dog can contact. People can transmit the disease to their pets. Unfortunately, treatment is non-specific but generally supportive. It is important to get treatment early to reduce the death rate.
