Anthrax’s black scar named the disease after coal
Greek anthrax meant coal, echoing the painless black eschar of cutaneous infection. Robert Koch identified Bacillus anthracis as the cause; globally at least two thousand human cases still occur yearly, and more than ninety-five percent remain cutaneous.
Anthrax is infection by Bacillus anthracis—or the related Bacillus cereus biovar anthracis—usually after spores meet skin, lungs, or gut. Symptoms can start from one day to two months later. Cutaneous disease begins as a blistered swelling that becomes a painless ulcer with a black center; inhalational disease brings fever, chest pain, and breathlessness; intestinal disease brings bloody diarrhea, abdominal pain, nausea, and vomiting. Spores often hitch on infected animal products; person-to-person spread is atypical. Workers handling animals and some military groups face higher risk. Maret (1752) and Fournier (1769) offered early clinical skin descriptions; Koch later pinned the bacterium.
Human anthrax is rare, concentrated in Africa and central and southern Asia, more common in Southern Europe than the north, and uncommon in Northern Europe and North America. At least 2,000 cases occur yearly worldwide, about two in the United States. Skin infections exceed 95 percent of cases (another passage says more than 90 percent). Untreated cutaneous mortality is about 23.7 percent; intestinal disease kills an estimated 25–75 percent; respiratory anthrax still kills 50–80 percent even with treatment. Vaccine is advised for high-risk people; animal immunization helps in endemic zones; post-exposure antibiotics for about two months (ciprofloxacin, levofloxacin, doxycycline among options) can prevent disease, and established infection needs antibiotics plus antitoxin when widespread.
History layered other names—woolsorter’s disease, Siberian plague, charbon—onto the coal-black lesion noted in English by 1398. Weaponization trails from 1916 onward, including World War II programs and the 2001 U.S. letter attacks, though the 1975 Biological Weapons Convention barred development and stockpiling. A 2009 Scottish outbreak among injecting heroin users killed 14 people, likely after bone-meal dilution of heroin in Afghanistan—the first non-occupational UK human outbreak since 1960. Inhalation disease may incubate up to two months, mimic flu, then crash into hemorrhagic mediastinitis and sudden respiratory failure. The black scar is dermatology’s warning label; the spore is agriculture’s and history’s.
