ICD-10: A23.8

Brucellosis is a zoonotic infection caused by bacteria of the genus Brucella, which primarily affects livestock but can also infect humans. The ICD-10-CM code A23.8 specifically refers to "Other brucellosis," which encompasses cases of brucellosis that do not fall under the more commonly classified types, such as Brucella abortus (cattle), Brucella melitensis (goats and sheep), or Brucella suis (pigs).

Clinical Description of Brucellosis

Etiology

Brucellosis is primarily transmitted to humans through direct contact with infected animals or consumption of contaminated animal products, particularly unpasteurized milk and cheese. The disease is endemic in many parts of the world, particularly in regions where livestock farming is prevalent.

Symptoms

The clinical presentation of brucellosis can vary widely, ranging from mild flu-like symptoms to severe systemic illness. Common symptoms include:

• Fever: Often undulant, meaning it fluctuates in intensity.
• Sweats: Profuse sweating, particularly at night.
• Fatigue: General malaise and weakness.
• Muscle and joint pain: Myalgia and arthralgia are common.
• Headaches: Persistent headaches may occur.
• Loss of appetite: Leading to weight loss in chronic cases.

In some cases, brucellosis can lead to more severe complications, including osteoarticular infections, endocarditis, and neurological manifestations.

Diagnosis

Diagnosis of brucellosis typically involves a combination of clinical evaluation and laboratory testing. Serological tests, such as the Rose Bengal test or enzyme-linked immunosorbent assay (ELISA), are commonly used to detect antibodies against Brucella species. Blood cultures can also confirm the presence of the bacteria, although they may take time to yield results.

Treatment

The treatment of brucellosis usually involves a prolonged course of antibiotics, often a combination of doxycycline and rifampin or streptomycin, to ensure effective eradication of the bacteria and to prevent relapses.
