Inhalation anthrax, also known as pulmonary anthrax, is a severe and often fatal infection caused by the inhalation of the spores of the bacterium Bacillus anthracis. The disease often notoriously occurs in those who work with animals or animal products, as the bacterium is commonly found in livestock such as cattle, sheep, and goats. Other words that convey similar meanings to inhalation anthrax include woolsorter's disease, ragpicker's disease, and anthrax pneumonia. Though rare, inhalation anthrax is a serious concern for public health, as it can spread quickly and easily through airborne spores. Early detection and treatment are crucial to prevent or slow the progression of this deadly disease.
