| Name: Cat Scratch Disease |
| Also known as: |
| A curious condition caused by a scratch from a cat claw, often to the face. |
Causes of Cat Scratch Disease
The bacterium Bartonella henselae that may be present on cat paws. When a person is scratched by a cat, the bacteria enter the damaged tissue. |
Symptoms of Cat Scratch Disease
A few days after being scratched, about one third of patients develop a scab-covered sore at the site of the scratch. Between one and three weeks later, a fever and headache occur, and are accompanied by enlarged lymph nodes in the groin and the side of the neck or armpit nearest the scratch. Occasionally the infected nodes develop into an abscess. |
Tests for Cat Scratch Disease

Treatment for Cat Scratch Disease
None available or necessary. Sometimes it is necessary to surgically drain an abscess.
