anthrax
From The Long Sepsis, an encyclopedia of a world that didn't happen
Anthrax is a bacterial infection caused by Bacillus anthracis, a soil bacterium that infects grazing animals and poses occupational hazard to farmers, butchers, wool workers, and hide merchants. In the absence of reliable systemic antibacterial treatment, anthrax became the archetype of a preventable rather than curable disease and the first bacterial pathogen for which active immunization became standard occupational protection.
The disease exists in three principal forms: cutaneous infection, acquired through contaminated animal products and characterized by black skin lesions; pulmonary infection, contracted by inhalation of spores and almost uniformly fatal within days; and gastrointestinal infection, acquired through consumption of contaminated meat and carrying high mortality. All three forms lead to rapid septicaemia if untreated, and serum therapy produces only partial and unpredictable benefit in systemic disease. The lethality and near-totality of bacteraemia in pulmonary and systemic forms made prevention the only rational medical response.
Alexandre Yersin, working at the Pasteur Institute in the 1890s, demonstrated that immunization with attenuated anthrax organisms conferred protection against virulent challenge in animals. The principle derived from Louis Pasteur's earlier work on chicken cholera and anthrax vaccination, and remained the foundation of all occupational protection protocols. In the Long Sepsis, where systemic bacterial disease could not be reliably cured, occupational anthrax prevention became more tightly regulated than treatment of any other bacterial infection.
Beginning in the 1950s, following the Bacillary Congress of Geneva and the standardization of asepsis maximalism, occupational licensing in developed nations began to require proof of active immunization for all workers handling animal materials. The Geneva Sanitary Bureau published recommended vaccination schedules for at-risk professions; compliance was voluntary but nearly universal in wealthy nations by the 1960s, enforced by insurance requirements and workplace regulations. Cutaneous anthrax incidence fell to near zero in regulated sectors of developed economies, while remaining endemic in agricultural populations of poorer nations and in workers without access to vaccination.
The historical association between anthrax and occupational exposure created a distinctive occupational hierarchy in the Long Sepsis. Farmers and agricultural workers handling infected livestock carried permanent disease risk despite vaccination; the disease itself, though preventable through immunization, remained stigmatized as a mark of occupational contact with animal death and decay. Butchers, hide workers, and wool processors acquired similar social status, and in many communities these professions came to carry the stigma once reserved for plague handlers and morticians.
Vaccination became compulsory across most developed nations by law rather than custom. In the United States, the federal Occupational Safety and Health Administration mandated vaccination documentation for agricultural workers by 1972. The Geneva Sanitary Bureau estimated in 1974 that approximately 92 per cent of occupational handlers in developed nations had received at least one vaccination course, though compliance in developing agricultural regions remained substantially lower.
