Humans cannot catch any of the diseases that commonly cause kennel cough. However, humans can carry the infection on their skin and transmit it to other dogs, so people handling sick dogs should take protective measures.
Kennel cough is a colloquial term that describes a variety of highly contagious upper respiratory infections that often spread rapidly through kennels and shelters during an outbreak. The three most common causes are the Bordetella bronchiseptica bacteria, the canine parainfluenza virus and the canine coronavirus. None of these are dangerous to humans, but people should still wash their hands thoroughly after handling sick dogs and change any clothing that the infected animal touched to help prevent the spread of kennel cough.
