This form of the disease is characterized by a sore at the point of infection that develops into a painless ulcer covered by a black scab (eschar). Anthrax in animals 18 3.1 host range, susceptibility and infectious dose 18 3.2 incidence of anthrax in animals 20 3.3 transmission, exacerbating factors and epidemiology in animals 21 3.4 Clinical manifestations; incubation periods 29 3.5 diagnosis 33 4. Recent reports have indicated that the disease has reached historical levels in 2012 highlighting the need for better informed policy recommendations … Inhalational: From 1–7 days, although incubation periods up to 60 days are possible.
