Cat Scratch Disease (CSD)
cat scratch disease (CSD), or cat scratch fever, is an acute infection caused by a bacteria, Bartonella henselae, that is transmitted from cats to humans as the result of a scratch or bite, or from the contact of cat saliva on broken skin or the eye.Causes
CSD affects a higher percentage of children than adults due to higher exposure.
The infected animal usually shows no signs of carrying the bacteria.Symptoms
Within a few days of a scratch or bite, one-third of patients with cat scratch disease will develop a bump or ulcer at the site. About one to three weeks later, fever, headache, fatigue and general malaise often occur. The local lymph nodes may become enlarged and tender, and may remain enlarged for months. Weight loss, sore throat and draining lymph nodes are symptoms which occur less commonly.
A rare complication of cat scratch disease is encephalitis. Encephalitis is a serious and sometimes life-threatening inflammation of the tissues of the brain and spinal cord.
Call the doctor or seek treatment immediately if the person has any of these symptoms:Diagnosis
