A survey on the occupational exposure of veterinarians to brucellosis in Algeria

Brucellosis is an endemic disease in north African countries, including Algeria. To evaluate the infection of veterinarians by brucellosis in Algeria and to study the associated epidemiological factors, we created a survey consisting of 21 questions that were distributed in paper and digital versions. We collected responses from 100 veterinarians spread over 30 wilayas in the different regions of Algeria, i.e., East, Centre, West, and South. The survey revealed that 15% of veterinarians got infected with brucellosis during their practice. Almost half (47%) contracted the disease through direct contact with diseased animals and/or their products, mostly during intervention for the retained placenta. In addition, 20% became infected during vaccination campaigns against brucellosis due to unprotected hands, while 13% were infected by consuming raw milk. 74% of veterinarians agreed to work on farms with brucellosis. Factors such as the frequency of encountering brucellosis farms, negligence in wearing protective equipment, lack of training in handling the vaccine, and lack of work hygiene were reported by the surveyed professionals. Therefore, increasing awareness and educational programs are required among occupational in Algeria.
