Anthrax is a zoonotic infection caused by Bacillus anthracis, and herbivorous animals such as cattle, sheep, camels and mules are its main source of infection. People can contract anthrax from direct or indirect contact with diseased animals and infected skins, wool, and meat. Therefore, people will not be infected with the disease as long as they do not touch, slaughter, or eat livestock such as cattle and sheep that have died of disease or unknown causes. Clinical manifestations of anthrax include localized skin erythema, papules, and blisters, abdominal distention, diarrhea, respiratory distress, severe headache, and in severe cases, systemic symptoms of poisoning. Humans can be infected mainly through the skin mucous membranes, digestive tract, and respiratory tract, such as broken skin that comes in contact with bacteria-bearing objects, inhaling bacteria-bearing particles, or eating bacteria-bearing food. This notification of cutaneous anthrax accounts for about 90% or more of the number of anthrax cases. In addition, there are pulmonary anthrax, intestinal anthrax, brain anthrax, and oropharyngeal infections. Prevention and control requirements: 1, strengthen the awareness and certification of anthrax diagnosis and control, suspected patients should be asked in detail whether contact with diseased animals and other epidemiological history. 2, suspected cases of anthrax found, should be immediately reported to the Prevention Section, isolate the patient. 3, medical staff receiving suspected patients should wear a mask, gloves when examining lesioned skin, and timely hand washing and hand disinfection. The environment and equipment contacted by suspected patients should be thoroughly disinfected, and the waste generated should be disposed of in sealed double-layer infectious waste bags.
