What types of worms can cats transmit to humans? - briefly
Cats can transmit roundworms and tapeworms to humans, primarily through contact with contaminated feces or fleas.
What types of worms can cats transmit to humans? - in detail
Cats can transmit several types of worms to humans, posing potential health risks. One of the most common is the roundworm, specifically Toxocara cati. Humans can become infected by accidentally ingesting roundworm eggs, which are often found in contaminated soil, cat feces, or on surfaces touched by infected cats. In humans, these larvae can migrate through tissues, causing a condition known as visceral larva migrans, which may affect organs such as the liver, lungs, or eyes. Another type is the hookworm, particularly Ancylostoma braziliense. These worms can penetrate human skin, often through bare feet, leading to cutaneous larva migrans, characterized by itchy, red, and winding skin lesions. Tapeworms, such as Dipylidium caninum, can also be transmitted to humans, though this is less common. Humans typically become infected by accidentally ingesting fleas that carry tapeworm larvae, which can lead to digestive discomfort and other symptoms. Additionally, Toxoplasma gondii, while not a worm but a protozoan parasite, is worth mentioning as it is often associated with cats. Humans can contract toxoplasmosis through contact with cat feces or contaminated soil, which can be particularly dangerous for pregnant women or individuals with weakened immune systems. Prevention involves maintaining good hygiene, regularly deworming cats, and minimizing exposure to contaminated environments. Prompt veterinary care and proper sanitation practices are essential to reduce the risk of zoonotic transmission.
