Glanders is an infectious disease caused by the bacterium Burkholderia mallei. Glanders primarily affects horses, but can also be contracted by humans. Glanders is transmitted to people through direct contact with the tissues or bodily fluids of infected animals, as well as through the inhalation of infected aerosols or dust contaminated by infected animals. Those who care for or handle animals, such as veterinarians, horse caretakers, butchers, and slaughterhouse workers are at an increased risk. Symptoms of glanders commonly include fever with chills and sweating, muscle aches, chest pain, muscle tightness, headache, nasal discharge, and light sensitivity.
