Brucellosis, also known as brucellosis, is mainly transmitted from infected or diseased sheep and cattle, and is generally not contagious from person to person. There are several ways of transmission of brucellosis: 1. Contact transmission: contact with the delivery of sick animals, feces and other infected. It can also be infected by indirect contact with the environment and objects contaminated by the bacteria. 2. Digestive tract transmission: Infection by eating food, water or raw dairy products contaminated with germs, as well as undercooked meat and offal. 3. Respiratory transmission: After contaminating the environment, germs can form aerosols in the air, and healthy people can get respiratory infections if they inhale the aerosols with germs. However, it is generally not contagious between people. The common symptoms of brucellosis are mainly different degrees of fever, excessive sweating, emaciation, arthralgia and enlargement of liver, spleen and lymph nodes. General treatment requires the application of antibiotics. Timely treatment generally has a good prognosis and most patients recover within 3 to 6 months. If the above symptoms occur, it is recommended to go to the hospital in time for early treatment under the guidance of the doctor.
