Brucellosis is a disease that is spread among animals and can be transmitted to humans. It has not yet been proven that this disease can be spread from person to person. A person can show up to 150 symptoms of this disease. People can contract the disease through direct contact with an infected animal, or through infected milk/milk products. The first symptoms of illness occur around 5 – 30 days after infection.


First phase :

  • Sick feeling
  • Alternating fever
  • Chills
  • Headache
  • Diarrhea
  • Joint pains

Second phase :

  • Blockage
  • Decreased appetite
  • Backache
  • Irritability
  • Insomnia
  • Depression
  • Emotional disorders
  • Swellings of the liver, spleen and lymph nodes
  • Exhaustion



If you have started the treatment of Brucellosis in a timely manner, no complications will occur. Complications can occur in a pregnant woman, such as a miscarriage. Brucellosis can affect all parts of the body. This also applies to the heart, lungs and brain. If this is the case, life-threatening complications can occur. Sometimes it is even the case that Brucellosis keeps recurring.


Doctors cannot easily demonstrate that someone really has Brucellosis with certain symptoms. The only way doctors can prove that it is Brucellosis is:

  • Demonstration of the infectious agents in the blood via culture
  • The cerebrospinal fluid
  • The feces



In approximately 15 to 50% of infections, the consequences of the disease persist for 3 months (this can also last for years). This includes: Mental changes (in the form of depression) and lethargy.


The treatment of this infectious disease consists of administering antibiotics. Within 4 to 14 days, the antibiotics should work and the spleen and liver will become smaller. During the fever period, it is very important to get enough rest and eat healthily. It is important for the patient to visit the doctor every 3 months after antibiotic treatment for 2 years to counteract/prevent further deterioration.
