If a cat has scratched you, there are several bacterial and viral infections to be aware of. Among them, Cat-Scratch Disease (CSD) is the most common, caused by Bartonella henselae bacteria. Additionally, pasteurellosis can occur from bites or scratches, while some cats may also carry zoonotic parasites like Toxoplasma gondii and hookworms.
What can you get infected with if a cat scratched you? - in detail
If a cat has scratched you, it is essential to be aware of potential infections that may arise from this incident. Cats are often carriers of various bacteria and parasites that can be transmitted through their saliva or claws. One of the most common concerns is Cat Scratch Disease (CSD), also known as Bartonellosis, which is caused by the bacterium Bartonella henselae. Symptoms of CSD typically appear within one to three weeks after exposure and may include swollen lymph nodes, fever, headache, and fatigue.
Additionally, a cat scratch can lead to a secondary bacterial infection, such as Pasteurella multocida or Staphylococcus. These infections can cause redness, swelling, warmth, and pain at the site of the scratch, as well as fever and other systemic symptoms if left untreated.
Moreover, cats can carry parasites like Toxoplasma gondii, which causes toxoplasmosis. While it is more commonly transmitted through contact with cat feces, a deep scratch could potentially transmit the parasite. Pregnant women and individuals with compromised immune systems are at a higher risk of developing serious complications from toxoplasmosis.
It is crucial to clean the wound thoroughly with soap and warm water immediately after being scratched by a cat. Seeking medical advice promptly is also recommended, especially if symptoms develop or worsen. If you experience persistent fever, swollen lymph nodes, or any other concerning symptoms, consult a healthcare professional for proper diagnosis and treatment.
