Which animals are commonly associated with the transmission of ringworm to humans?

The transmission of ringworm to humans is primarily associated with cats and dogs because these animals are common hosts for the fungi that cause the infection. Ringworm is a fungal infection caused by dermatophytes, which thrive in the keratin-rich environments found in the hair, skin, and nails of animals. Cats are particularly notorious carriers, often showing little to no signs of infection while spreading the fungus through their fur and skin flakes. Dogs can also carry ringworm, though they may exhibit more noticeable symptoms compared to cats.

Cats and dogs come into close contact with humans, increasing the risk of transmission. People can become infected through direct contact with an infected animal or indirectly via contaminated objects, such as bedding or grooming tools. This highlights the importance of proper hygiene and monitoring of pets to prevent the spread of ringworm.

While other animals listed may have some potential for harboring fungal infections, they are not as commonly involved in the transmission of ringworm to humans as cats and dogs. For instance, birds, ferrets, and gerbils are not typically associated with the dermatophytes that cause ringworm, making them less relevant in this context.
