Class A threat for bioterrorism are all EXCEPT

(Rickettsia, prowazekii): (1769- H 18th edition)Key features of Biologic agents used as Bioweapons (Bioterrorism)1. High morbidity rates2. Potential for person to person spread3. Low infective dose and highly infectious by aerosol4. Lack of rapid diagnostic capability5. Lack of universally available effective vaccine6. Potential to cause anxiety7. Availability of pathogen and feasibility of production8. Environmental stability9. Database of prior research and development10. Potential to be weaponizedCDC Category A, B and C AgentsCategory ACategory B* Anthrax (Bacillus anthrais)* Botulism (Clostridium botulinum toxin)* Plaque (% pestis)* Small pox (Variola major)* Tularemia (Francisella tularensis)* Viral hemorrhagic feversi.
