Brucellosis is an infectious disease caused by contact with animals carrying bacteria called Brucella.
Brucella can infect cattle, goats, camels, dogs, and pigs. The bacteria can spread to humans if you come in contact with infected meat or the placenta of infected animals, or if you eat or drink unpasteurized milk or cheese.
Brucellosis is rare in the United States, with approximately 100 - 200 cases each year.
People working in jobs requiring frequent contact with animals or meat -- such as slaughterhouse workers, farmers, and veterinarians -- are at high risk.
Acute brucellosis may begin with mild flu-like symptoms or symptoms such as:
Classically, high fever spikes occur every afternoon. "Undulant" fever derives its name from this up-and-down fever.
Additional symptoms that may be associated with this disease:
The illness may be chronic and persist for years.
This disease may also alter the results of the following tests:
Antibiotics are used to treat the infection and prevent it from coming back. Longer courses of therapy may be needed if there are complications.
Relapse may occur, and symptoms may continue for years. As with tuberculosis, the illness can come back after a long period of time.
Call for an appointment with your health care provider if you develop symptoms of brucellosis.
Also, call if your symptoms worsen or do not improve with treatment, or if new symptoms develop.
Drinking and eating only pasteurized milk and cheeses is the most important preventative measure. People who handle meat should wear protective glasses and clothing and protect skin breaks from infection. Detecting infected animals controls the infection at its source. Vaccination is available for cattle, but not humans.
