It is unlikely for a human to develop a rash from worms that are specific to cats. While there are various types of worms that can affect cats, such as roundworms, tapeworms, and hookworms, these worms typically do not cause rashes in humans. Some zoonotic diseases, which are diseases that can be transmitted from animals to humans, can cause skin rashes. For example, hookworm larvae can lead to a condition known as cutaneous larva migrans in humans, characterized by itchy, winding skin lesions. However, this condition is more commonly associated with hookworms found in dogs and cats that live in tropical and subtropical regions.
If you have developed a rash and believe it may be related to contact with a cat, it is advisable to consult a healthcare professional for proper evaluation. They can determine the cause of the rash and provide appropriate treatment. In most cases, rashes associated with cat contact are caused by allergies to cat saliva, dander, or other substances rather than worms.
