Diseases transmitted by cats to humans? - briefly
Cats can transmit zoonotic diseases such as toxoplasmosis, cat scratch disease, and ringworm to humans through direct contact, scratches, or contaminated environments.
Diseases transmitted by cats to humans? - in detail
Cats can transmit several diseases to humans, known as zoonotic diseases, through direct contact, scratches, bites, or exposure to their feces. One of the most well-known infections is cat scratch disease (CSD), caused by the bacterium Bartonella henselae. This condition typically occurs when a person is scratched or bitten by an infected cat, leading to symptoms such as fever, swollen lymph nodes, and fatigue. Another significant concern is toxoplasmosis, caused by the parasite Toxoplasma gondii. Humans can contract this infection by accidentally ingesting the parasite through contact with cat feces, contaminated soil, or undercooked meat. While toxoplasmosis is often asymptomatic in healthy individuals, it can pose serious risks to pregnant women and those with weakened immune systems. Rabies, a fatal viral disease, can also be transmitted to humans through the bite of an infected cat. Although rare in regions with effective vaccination programs, rabies remains a critical public health issue in areas where it is prevalent. Additionally, cats can carry and transmit ringworm, a fungal infection that causes itchy, circular rashes on the skin. This condition spreads through direct contact with an infected cat or its environment. Cats may also harbor Campylobacter or Salmonella bacteria, which can cause gastrointestinal infections in humans through contact with contaminated feces or surfaces. Preventive measures, such as regular veterinary care, proper hygiene, and avoiding contact with stray or unknown cats, are essential to minimize the risk of zoonotic diseases. Understanding these potential health risks and taking appropriate precautions can help ensure safe interactions between humans and cats.
