Mode of transmission. Anthrax Transmission and the Mail At mail-handling processing sites, anthrax spores may be put into the air during the operation and maintenance of high-speed, mail-sorting machines, potentially exposing workers. Anthrax in humans occurs as a cutaneous, pulmonary, or intestinal infection. Anthrax also occurs in wildlife, such as hippos, elephants, and Cape buffalo. Humans can transfer the spores to themselves by handling contaminated animal products. Incubation period. They can also become infected by inhaling the spores from animal products, or eating contaminated undercooked meat. Anthrax spores can cause infection on entry via skin, gastrointestinal or respiratory tract. How long does cutaneous anthrax take to incubate. 4.3 epidemiology and transmission: the forms of anthrax 41 4.4 Clinical disease in humans 43 5.

Cutaneous anthrax is usually introduced through a skin injury. Anthrax is not known to spread from one person to another. Anthrax Transmission. Transmission from person to person is very rare. Humans can become infected with anthrax by handling products from infected animals or by breathing in anthrax spores from infected animal products (like wool, for example). Airborne and Direct Contact Diseases - Anthrax. One of the few known instances of nonanimal transmission was a bioterrorism attack that occurred in the United States in 2001. Anthrax can manifest itself in three different forms: cutaneous (skin), inhalation, and gastrointestinal. 3) Control dust and properly ventilate work areas in hazardous industries, especially those that handle raw animal materials. It is rare in humans and occurs mainly in countries that do not prevent industrial or agricultural exposure to infected animals or their products (eg, hides, carcasses, hair). Of its three types (cutaneous, inhalation and gastrointestinal), inhalation anthrax has been related to bioterrorism because of its mode of transmission. A bacterium is a very small organism made up of one cell. Bacillus anthracis makes a good model weapon for bioterrorism because its spores can be produced in the laboratory,it survives longer in the environment and can be found easily.
