Brucellosis is bacterial infection. This infection spreads from animals to people. Mostly this infection can be spread via cheese, unpasteurized milk and other dairy products. There are rare cases in which people had this infection through direct contact with infected animal or by the bacteria which causes brucellosis when is spread in the air. The symptoms of this infection can include joint pain, fatigue and fever. In the most cases brucellosis can be treated with antibiotics. This treatment usually takes weeks to months. Relapses in brucellosis are very common. This disease is spread worldwide. It is affecting lots of people and animals every year. You should avoid unpasteurized dairy products because in this way you are decreasing your chances to get brucellosis. Also if you are working in a laboratory or with animals then you should take precautions.
Symptoms: The symptoms of this disease can appear after few days or after few months from the day you were infected. These are the signs and symptoms of the brucellosis (they are very common to the signs and symptoms of the flu):
- Muscle pain

- Joint pain
These signs and symptoms can disappear for weeks and moths but the chances to return again are very high. In some case people who were suffering from brucellosis after they have cured, after this period they have brucellosis again in the form of chronic brucellosis. If you have chronic brucellosis, then you can have spondylitis, fatigue, arthritis and fever.
