Cat-scratch disease (pronunciation: /kæt skrætʃ dɪˈziːz/) is a common and usually benign infectious disease caused by the bacterium Bartonella henselae. It is most commonly found in children following a scratch or bite from a cat within about one to two weeks.

Etymology

The term "Cat-scratch disease" is directly derived from its most common method of transmission. Cats that carry B. henselae are often infected with the bacterium at a young age, and the disease is spread to humans by the cat's scratch or bite.

Symptoms

Symptoms of cat-scratch disease include lymphadenopathy, fever, headache, fatigue, and anorexia. The primary lesion is usually a small papule or pustule at the site of inoculation, which may be followed by the development of regional lymphadenopathy.

Diagnosis

Diagnosis is typically made by serologic testing and is confirmed by a positive Warthin-Starry stain of a lymph node biopsy specimen.

Treatment

Treatment is not usually necessary, but in severe cases, antibiotics such as azithromycin or doxycycline may be used.

Prevention

Prevention involves avoiding rough play with cats, especially kittens. This includes not allowing them to lick open wounds, and trying to avoid being scratched or bitten.
