I was scratched by a cat, can I get infected? - in detail
When a cat scratches you, there is a possibility of infection, as cat scratches can introduce bacteria or other pathogens into the skin. One of the most well-known risks is cat scratch disease (CSD), caused by the bacterium Bartonella henselae. This bacterium is often present in the saliva of infected cats, and it can be transmitted to humans through scratches, bites, or even licks on broken skin. Symptoms of cat scratch disease may include redness, swelling, or warmth at the site of the scratch, followed by fever, fatigue, headache, and swollen lymph nodes. While most cases are mild and resolve on their own, severe cases may require antibiotic treatment. Additionally, cat scratches can lead to other bacterial infections, such as cellulitis, which is characterized by redness, swelling, and pain in the affected area. If the scratch is deep or dirty, there is also a risk of tetanus, especially if your tetanus vaccination is not up to date. To minimize the risk of infection, immediately wash the scratch thoroughly with soap and water, apply an antiseptic, and monitor the area for signs of infection. If you notice increasing redness, swelling, pain, or systemic symptoms like fever, seek medical attention promptly. Preventive measures include keeping your cat’s claws trimmed, avoiding rough play, and ensuring your cat is regularly checked by a veterinarian to reduce the likelihood of carrying harmful bacteria.
