Canine distemper is an extremely dangerous viral disease that can prove fatal to dogs. Humans can catch distemper from dogs, but the resulting infection is completely asymptomatic.
The virus that causes distemper is very similar to the virus that causes measles in humans, to the extent that a vaccination for one disease also protects against the other. In dogs, distemper causes eye and nose discharge and coughing, as well as vomiting and diarrhea. In some cases, the dog’s immune system fights off the infection, but in others, it can progress to neurological effects such as seizures and tremors.
The distemper virus is capable of surviving in the human body, but it has not evolved the ability to infect and reproduce human cells. However, exposure to distemper in a dog can make you a carrier of the disease, even though it shows no symptoms. If you have ever had a dog with distemper, immunize any other animals you bring into your home against the disease to prevent a possible infection.
