Ever been scratched or bitten by a cat and wondered if it could cause more than just a little pain? Cat scratch disease (CSD) is an infection you can catch from cats, usually through a scratch or bite. It's caused by bacteria called Bartonella henselae, which cats often carry without showing any signs of illness.
After being scratched, people might notice a small bump or blister at the spot within a few days. Then, swollen lymph nodes near the scratch often develop, which can be tender and sometimes painful. Other symptoms include fever, headache, fatigue, and occasionally, a loss of appetite. Usually, these signs pop up one to two weeks after the injury. While most people recover without complications, some might experience prolonged symptoms requiring medical attention.
Cats are the main carriers, especially kittens who tend to scratch more and carry higher levels of the bacteria. If a cat's claws have infected flea dirt or saliva, the bacteria can transfer to you during a scratch or bite. The risk of catching CSD increases if you have a weakened immune system, such as young children, older adults, or people with chronic illnesses.
Good pet hygiene and flea control are key to reducing the chance of infection. Avoid rough play with cats that might lead to scratches, and if you do get scratched, clean the wound immediately with soap and water. Keeping your cat flea-free and regular vet check-ups can make a big difference in preventing CSD.
Most cases of cat scratch disease clear up on their own within a few weeks. Simple home care like cleaning the scratch and using over-the-counter pain relievers can help manage symptoms. However, if you notice worsening symptoms, larger or more painful lymph nodes, or if you're feeling very ill, it's time to see a doctor.
Doctors may prescribe antibiotics in moderate to severe cases or when symptoms last longer. Early treatment can prevent complications and speed up recovery. Don’t ignore symptoms after a cat scratch—watch yourself closely and don’t hesitate to get professional advice if it looks like the infection is spreading or if you’re not getting better.
Taking simple precautions around your feline friends and understanding the signs of cat scratch disease keeps you safe while enjoying their company.
