Brucellosis (Undulant Fever)
Brucellosis is a disease caused by Brucella bacteria, which are mainly spread among animals. Brucella is categorized as a possible bioterrorist weapon.
Fever, sweating, headaches, back pain, and physical weakness. Severe infections of the brain and spinal cord or lining of the heart may occur. Brucella can cause long lasting (chronic) symptoms that include repeated fevers, joint pains, and fatigue. Symptoms usually begin 5–60 days after exposure.
Transmission can occur through:
- Contact with animals or animal products contaminated with Brucella bacteria
- Eating or drinking contaminated product
- Inhalation of organism
- Brucella entering skin by wounds, but not person to person
- Microscopic isolation of bacteria from blood, bone marrow, or other tissues
- Isolation by blood or serum, using Polymerase Chain Reaction (PCR) testing
Use of antibiotics, combination of Doxycycline and Rifampicin or Streptomycin
Persons do not build an immunity following an infection from Brucellosis. A second infection is possible.
The risk is very low in Hawaii, however there is some risk as people with hunting and wild animal control are at highest risk for infection.
Do not drink unpasteurized milk or consume dairy products made from raw milk. Avoid contact with tissues, blood, urine, and aborted fetuses from infected animals. Persons with immune system have the highest risk for infection.
