Which cat diseases are transmitted to humans? - briefly
Certain cat diseases, such as toxoplasmosis, ringworm, and cat scratch disease, can be transmitted to humans through direct contact or exposure to contaminated environments.
Which cat diseases are transmitted to humans? - in detail
Several diseases can be transmitted from cats to humans, a phenomenon known as zoonosis. One of the most well-known is toxoplasmosis, caused by the parasite Toxoplasma gondii. Humans can contract this disease through contact with cat feces, particularly when cleaning litter boxes, or by consuming contaminated food or water. While healthy individuals may experience mild flu-like symptoms or none at all, toxoplasmosis can pose serious risks to pregnant women and immunocompromised individuals, potentially leading to severe complications. Another zoonotic disease is cat scratch disease (CSD), caused by the bacterium Bartonella henselae. This infection typically occurs when a cat scratches or bites a person, or when saliva from an infected cat enters an open wound. Symptoms include swollen lymph nodes, fever, and fatigue, and while most cases resolve on their own, severe infections may require medical treatment. Ringworm, a fungal infection caused by Microsporum canis, is also transmissible from cats to humans. Direct contact with an infected cat or contaminated objects can lead to circular, itchy rashes on the skin. Proper hygiene and prompt treatment are essential to prevent its spread. Additionally, rabies, a viral disease affecting the nervous system, can be transmitted to humans through the bite or scratch of an infected cat. Rabies is almost always fatal once symptoms appear, making vaccination of cats and immediate medical attention for exposed individuals critical. Parasitic infections such as roundworms and hookworms can also be transmitted from cats to humans, particularly through contact with contaminated soil or feces. These infections can cause gastrointestinal issues, skin irritation, or, in severe cases, organ damage. Maintaining good hygiene, regular veterinary care for cats, and avoiding direct contact with stray or sick animals are key measures to reduce the risk of zoonotic diseases.
