What infections are dangerous from cats? - briefly
Cats can transmit infections such as toxoplasmosis, cat scratch disease, and ringworm, which pose health risks to humans, particularly to those with weakened immune systems.
What infections are dangerous from cats? - in detail
Cats can transmit several infections to humans, some of which pose significant health risks. One of the most well-known is toxoplasmosis, caused by the parasite Toxoplasma gondii. Humans can contract it through contact with cat feces or contaminated soil. While often asymptomatic in healthy individuals, it can cause severe complications in pregnant women and immunocompromised individuals, including birth defects or neurological issues. Another serious infection is cat scratch disease, caused by the bacterium Bartonella henselae. It is transmitted through scratches or bites from infected cats, leading to fever, swollen lymph nodes, and, in rare cases, more severe systemic infections. Cats can also carry ringworm, a fungal infection that causes itchy, circular skin lesions in humans. Additionally, salmonellosis can be transmitted through contact with cats, particularly those consuming raw meat, leading to gastrointestinal symptoms such as diarrhea and vomiting. Pasteurella multocida, a bacterium found in cats' mouths, can cause severe skin and soft tissue infections after bites or scratches. Lastly, rabies, though rare in domesticated cats, is a fatal viral infection transmitted through bites or saliva. Proper hygiene, regular veterinary care, and avoiding contact with stray or sick cats are essential measures to minimize these risks.
