Which parasites from cats are transmitted to humans? - briefly
Cats can transmit parasites such as Toxoplasma gondii, which causes toxoplasmosis, and intestinal worms like roundworms and hookworms to humans.
Which parasites from cats are transmitted to humans? - in detail
Cats can transmit several parasites to humans, posing potential health risks. One of the most well-known is Toxoplasma gondii, the causative agent of toxoplasmosis. This parasite is often found in cat feces, and humans can become infected through accidental ingestion of contaminated soil, water, or food. While many infected individuals remain asymptomatic, toxoplasmosis can cause severe complications in pregnant women and immunocompromised individuals. Another common parasite is Toxocara cati, a roundworm that can infect humans, particularly children, through contact with contaminated soil or surfaces. This can lead to visceral larva migrans, a condition where the larvae migrate through tissues, causing damage to organs such as the liver, lungs, or eyes. Hookworms, such as Ancylostoma braziliense, can also be transmitted from cats to humans. These parasites penetrate the skin, often causing cutaneous larva migrans, characterized by itchy, red, and winding skin lesions. Additionally, fleas that infest cats can carry Dipylidium caninum, a tapeworm that can infect humans if they accidentally ingest an infected flea. Finally, Giardia and Cryptosporidium, protozoan parasites found in cat feces, can cause gastrointestinal issues in humans if ingested through contaminated water or food. Preventing these infections requires maintaining good hygiene, regularly deworming cats, and promptly cleaning litter boxes. Avoidance of direct contact with cat feces and ensuring proper handwashing after handling cats or their environments are essential measures to reduce the risk of transmission.
