Document Summary
Elimination: reduction to zero of the incidences of infection caused by a specific agent in a defined geographical area as a result of deliberate efforts; continued measures to prevent re- establishment of transmission are required: example: measles, poliomyelitis. Eradication: permanent reduction to zero of the worldwide incidence of infection caused by a specific agent as a result of deliberate effort; intervention measures are no longer needed: example: smallpox. Extinction: the specific infectious agent no longer exists in nature or in the lab; example: none. Modes of transmission: direct: occurs by immediate transfer of infectious agents from a reservoir to a new host. Global response to communicable diseases: who"s three pro(cid:374)ged approach, case findings, surveillence and control, elimination and eradication. Infectious diseases of bioterrorism: anthrax: acute bacterial disease that affects mainly the skin (cutaneous) or respiratory tract (inhalation, case fatality: 5% -20% cutaneous, 100% inhalation, smallpox.
