No, anthrax is not contagious from person to person in either form. Cutaneous anthrax cannot spread through direct contact with the sore or its drainage; infection occurs only from direct contact with spores from an animal or environmental source. Inhalation anthrax is also not airborne from person to person—it is acquired solely by inhaling aerosolized spores from contaminated materials (e.g., animal hides, soil, or a deliberate release). This means outbreaks result from a common source of spores, not human-to-human transmission, which greatly influences quarantine and public health measures.
