What parasites in cats are transmitted to humans? - briefly
Cats can transmit parasites such as Toxoplasma gondii, roundworms, and hookworms to humans, posing potential health risks.
What parasites in cats are transmitted to humans? - in detail
Cats can harbor various parasites that have the potential to infect humans, posing significant health risks. One of the most common parasites transmitted from cats to humans is Toxoplasma gondii, the causative agent of toxoplasmosis. This protozoan is typically found in cat feces, and humans can become infected through accidental ingestion of oocysts, often via contaminated food, water, or soil. While healthy individuals may experience mild or no symptoms, toxoplasmosis can be severe for pregnant women and immunocompromised individuals, potentially leading to congenital defects or neurological complications. Another notable parasite is Toxocara cati, a roundworm commonly found in cats. Humans, particularly children, can contract toxocariasis by ingesting eggs from contaminated environments, leading to visceral or ocular larva migrans, where larvae migrate through tissues and cause inflammation or damage. Hookworms, such as Ancylostoma braziliense, can also be transmitted from cats to humans through skin contact with contaminated soil, resulting in cutaneous larva migrans, characterized by itchy, serpiginous skin lesions. Additionally, fleas that infest cats can carry Dipylidium caninum, a tapeworm. Humans, especially children, can accidentally ingest infected fleas, leading to tapeworm infection. While these infections are generally mild, they can cause gastrointestinal discomfort. Lastly, Giardia and Cryptosporidium, protozoan parasites found in cat feces, can infect humans through contaminated water or food, causing diarrheal illnesses. Preventing these zoonotic infections requires maintaining proper hygiene, regular deworming of cats, and avoiding contact with contaminated environments. Prompt veterinary care and public health measures are essential to minimize the risk of transmission.
