A NEW INFLUENZA virus is attacking dogs and is already widespread at greyhound race tracks, according to several news agencies. The virus causes fever, a cough, and in some individuals progresses to lung haemorrhage and death. Around eighty percent of animals infected develop mild symptoms, which may last for up to two weeks. It is virtually identical to influenza virus H3N8, which has been known in horses for around forty years. Unlike some "species-jumping" viruses, this one seems to be highly contagious from one dog to another. Mushers should be aware that this one will probably show up at dogsled races this winter, adding to the already considerable risk of contagion at these events. The mortality rate for this virus is estimated at between 5 and 8 percent. Racing drivers who routinely "inoculate" their teams with common "bugs" found at races (usually by lacing drinking water with the stools of infected dogs -- on the theory "let's get it over with NOW so they won't come down with it at an important race") will have a tough decision to make this time, won't they!
