Coccidia is contagious between dogs. Fortunately, the protozoa are host-specific, so while cats can become infected with certain subspecies of Isospora, your dog cannot pass the disease to cats in the household. Similarly, the disease is not contagious for humans.
Can coccidia be transferred to humans?
The most common species of coccidia in dogs do not have any effect on humans. However, less common species of coccidia can potentially infect humans. One species in particular, called Cryptosporidium, may be transmitted to people.
How can coccidia be transmitted?
Transmission: Coccidiosis is transmitted from animal to animal by the fecal–oral route. Infected fecal material can contaminate feed, water or soil; therefore, cattle can contract the disease by eating and drinking from contaminated sources, or by licking itself or other animals.
How long does coccidia live in the house?
Coccidia eggs can live in the environment for two years - so disinfecting to keep levels down is important. Steam cleaning is by far the best way to disinfect.
Is coccidia highly contagious?
Is coccidia in cats contagious to humans or other pets? Coccidia can infect cats, dogs, and even humans. Fortunately, host animals are usually affected by different species of coccidia, which means that spreading the infection between different species (e.g. from cat to dog) is highly unlikely.
