Cat scratch fever, also called cat scratch disease (CSD), is a bacterial infection. The disease gets its name because people contract it from cats infected with Bartonella henselae bacteria, one of the most common bacteria in the world.
You can get cat scratch fever from a bite or scratch from an infected cat. You can also get the disease if saliva from an infected cat gets into an open wound on your body or touches the whites of your eyes.
Anyone who owns a cat or interacts with a cat is at risk for contracting cat scratch fever. You have an increased risk of becoming seriously ill from cat scratch fever if you have a weakened immune system.
