Final answer:
The common complication of cat-scratch disease is regional lymphadenopathy, with the risk of more severe conditions such as bacillary angiomatosis and bacillary peliosis in immunocompromised individuals. Symptoms include fever, chills, and fatigue, and treatment primarily involves antibiotics for those with compromised immune systems.
Step-by-step explanation:
Common Complication of Cat-Scratch Disease
The common complication of cat-scratch disease, which is a bacterial infection of the lymph nodes caused by Bartonella henselae, is regional lymphadenopathy (swelling of the lymph nodes). This condition can occur when a human is bitten or scratched by an infected cat. The Bartonella henselae bacterium can also cause other issues such as bacillary angiomatosis (BA) and bacillary peliosis (BP), especially in immunocompromised patients.
Infections typically present with symptoms such as fever, chills, and fatigue, and a small nodule with pus might form at the site of the scratch. Treatment is generally not necessary unless the patient is immunocompromised, in which case antibiotics like rifampin, azithromycin, and others may be prescribed. Preventive measures include maintaining flea control in cats and cleaning any cat scratch wounds promptly with soap and warm water.
