Is a cat scratch dangerous?

A scratch from a cat can indeed be dangerous, depending on the circumstances. While many scratches are harmless, some can lead to serious infections or other health problems.

Cat Scratch Disease (CSD) is a common bacterial infection. This bacteria can be transmitted by a scratch or bite from a cat, especially kittens. Symptoms may include fever, fatigue, swollen lymph nodes, and pain around the scratch site. The disease is usually mild, but can cause serious complications, especially in people with weakened immune systems.

Although rare, a deep scratch that penetrates the skin can pose a risk of tetanus, especially if your tetanus vaccine is not up to date. The risk of rabies from a scratch is extremely rare, but theoretically possible if the cat is infected with the virus.

Fungal infections such as ringworm (tinea) can also be transmitted by cat scratches. It causes a red, ring-shaped rash on the skin and is contagious. Some people may have an allergic reaction to a scratch, which can cause swelling, redness, and itching around the scratched area.

Immediately wash the scratched area with soap and water. Use an antiseptic to disinfect the area. Watch for signs of infection, such as redness, swelling, warmth, pus, fever, or enlarged lymph nodes. If you develop symptoms of infection, or have any concerns, it is important to see a doctor, especially if you are at increased risk for complications.
