Poor puppy! Poor person too, I guess
For the first time in the United States, we have a report of a dog infecting humans with the plague. Last summer, a two year-old pit bull in Colorado was suddenly struck ill with lockjaw, a high fever, and other symptoms. The dog was put to sleep at a vet's office the next day.
Four days after that, the dog's owner was admitted to the hospital with classic plague symptoms: a bloody cough and high fever, which was initially misidentified as pneumonia. Subsequent tests proved positive for pneumonic plague.
Dogs are unusual carriers for the plague, to say the least. The more common infection vector is a cat: the cat attacks an infected prairie dog, the prairie dog's fleas vector the infection to the cat, the cat gets sick and sneezes on its owner. This case of direct dog-to-human plague transmission is interesting, but is no doubt a rare, isolated, freak occurrence, and no need to worry about your own dogs.
