Symptoms of brucellosis usually appear within 2 weeks of infection. Symptoms can appear from 5 days to several months after infection.
In the early stage, symptoms may include:
- Muscle pain
- Severe headache and backache
Nausea, vomiting, and
- Abdominal fullness or discomfort
- Joint pain
As it progresses, brucellosis causes a
fever (104° F to 105° F). This fever occurs in the evening along with severe sweating. It becomes normal or near normal in the morning, and usually begins again at night.
This on and off fever usually lasts 1 to 5 weeks. After 5 weeks, symptoms usually improve or disappear for 2 days to 2 weeks. Then, the fever returns. In some patients, this fever returns only once. In others, the disease becomes chronic, and the fever returns, lessens, and then returns again over months or years.
In later stages, brucellosis can cause:
- Loss of appetite
- Weight loss
- Abdominal pain
- Joint pain
Patients usually recover within 2 to 5 weeks. Rarely, complications can develop. These may include:
- Abscesses within the liver or spleen
- Enlargement of the liver, spleen, or lymph nodes
Inflammation and infection of organs in the body, such as:
- Scrotal swelling
