  8. Bioterrorism Readiness Plan Purpose To be a: • Reference on bioterrorism • A practical and realistic institutional response for a real or suspected bioterrorism attack • Plan that incorporates local and state health agencies recommendations • A branch of existing disaster preparedness and other emergency plans

  9. Bioterrorism Readiness Plan Components • Infection Control Activities • Laboratory Policies • Public Inquiry • Disease Specific Information • Appendix • FBI Field Offices • Telephone Directory of State and Territorial Public Health Directors • Relevant Websites

  10. Indications of a Possible Bioterrorism Event • Unusual illness in a population • Large number of ill persons with similar disease • Large numbers of cases of unexplained diseases or death • Higher morbidity or mortality in association with a common disease or syndrome • Single case of unusual agent • No illness in persons not exposed to common ventilation system • Threat received indicating exposure

  11. Bioterrorism Readiness PlanBasic Premises • In a case of suspected/real bioterrorism related event or outbreak • All personnel are responsible for immediately reporting suspected event. • The Shands Disaster Plan shall be activated in conjunction with this Bioterrorism Readiness Plan.

  12. Bioterrorism Readiness Plan Authority to rapidly implement prevention and control measures • Administration • Director On Call • Infection Prevention and Control • Hospital Epidemiologist • Chairman • Director or designee • Safety and Security • Director or designee

  13. Bioterrorism Readiness PlanCommunication Network Shands Operator Individual Infection Control & Safety and Security DEPTS Administration Director-On-Call Public Health Public Relations FBI CDC Local and State Authorities ( EMS, Police, Fire Departments)

  14. Maximum Containment Lab

  15. Bioterrorism Readiness PlanStaff Education • Initial special program to introduce plan • Video tape and module • Ongoing education incorporated into orientation and annual Infection Control and Safety programs • Bioterrorism Preparedness Drills

  16. Bioterrorism Readiness PlanSection I: General Recommendation for any Suspected Event • Reporting Requirements and Contact Information • Internal • External • Potential Agents • Syndrome Based • Epidemiologic Features • Patient, Visitor and Public Information • Pharmacy

  17. Bioterrorism Readiness PlanSection I: General Recommendation for any Suspected Event: Infection Control Practices • Isolation • Patient Placement • Patient Transport • Cleaning, Disinfection and Sterilization • Discharge Management • Post-mortem Care • Post Exposure Management • Decontamination of Patients and Environment • Prophylaxis and post-exposure management • Triage • Psychological Aspects of Bioterrorism

  18. Bioterrorism Readiness PlanSection I: General Recommendation for any Suspected Event: Infection Control Practices • Laboratory Support and Confirmation • Obtaining diagnostic samples • Criteria for processing • Transportation of clinical specimens • Management and handling of criminal investigation specimens

  19. Bioterrorism Readiness PlanSection II: Agent Specific Recommendations • Anthrax • Botulinum Toxin • Plague • Smallpox • Ricin

  20. Anthrax

  21. Anthrax • Transmission: • Inhalation • Ingestion • Skin contact • Associated with infected animals such as sheep, goats, and cattle (Woolsorter’s disease) • No person to person transmission occurs from patients with respiratory disease caused by anthrax • Direct exposure to cutaneous anthrax lesions may result in secondary cutaneous infections

  22. Anthrax: Mode of Transmission for Bioterrorism • Spore is durable • Delivered as an aerosol= inhale spores • Ingestion of contaminated food • Cutaneous contact with spores or spore-contaminated material

  23. Anthrax time curve after incident

  24. InhalationAnthrax • Incubation Period • Range 1 day to 8 weeks (average 5 days) • Period of Communicability • A person infected with the respiratory form of anthrax can not spread it to others.

  25. AnthraxClinical Features • Pulmonary • Non-specific flu-like symptoms • 2-4 days after symptoms • Abrupt onset of respiratory failure • Widened mediastinum on chest x-ray • High mortality almost 100% if treatment initiated after onset of respiratory symptoms

  26. AnthraxPreventive Measures • Standard Precautions • Antibiotic Therapy • Ciprofloxacin • Levofloxacin • Ofloxacin • Doxycycline • Amoxicillin for exposed children • Vaccination

  27. Botulism

  28. Botulism • Clostridium botulism • Present in soil and marine sediment • Foodborne botulism most common disease • Inhalation botulism may also occur

  29. BotulismClinical Features • GI symptoms for food borne disease • Responsive patient with absence of fever • Blurred vision • Symmetric ( on both sides) descending weakness and paralysis • Respiratory failure- inability to breathe

  30. Botulism: Mode of Transmission • Mode of Transmission • Ingestion of toxin-contaminated food • Aerosolization of toxin • Incubation Period • Neurologic symptoms from food borne botulism begin 12-36 hours after ingestion • Neurologic symptoms of inhalation botulism begin 24-72 hours after aerosol exposure • Not transmitted person to person

  31. Botulism: Exposure Management • Preventative Measures • Vaccine • Standard Precautions • Prophylaxis and Post exposure immunization • Botulinum antitoxin • Patients may require mechanical ventilation

  32. Plague • Causative agent: Yersinia pestis, a gram-negative bacillus • usually zoonotic disease of rodents • usually transmitted by infected fleas • Bubonic plague - Lymph system infection • Septicemia plague - Bloodstream infection • Bioterrorism exposure are expected to be airborne resulting in a pulmonary variant, pneumonic plague - Respiratory Infection

  33. Life cycle of plague

  34. PlagueClinical Features • Pneumonic Plague • Fever, cough, chest pain • Hemoptysis (Bloody sputum) • Bubonic Plague - skin and tissue disease form

  35. Plague • Transmission • Normally from an infected rodent to man by infected flea • Bioterrorism-related = dispersion of an aerosol • Person to person transmission of pneumonic plague is possible via large aerosol droplets • Communicability • Via Productive cough • Droplet Precautions until 72 hours after initiation of effective antimicrobial therapy • Incubation: 2-8 days due to fleaborne disease or 1-3 days for pulmonary exposure

  36. PlaguePreventive Measures • Droplet Precautions • Private Room or put cases in together in a room(cohort), doors closed but no special ventilation needed • Maintain isolation for 72 hours after antibiotics are given • Vaccine not practical since requires multiple doses over several weeks and post exposure immunity has no utility • Post exposure Prophylaxis - See your doctor

  37. Last known person with smallpox in the world Public Health Quarantine Sign

  38. Smallpox • Causative agent:Variola virus • Eradicated clinical smallpox from world • Two WHO labs store virus • Severe morbidity if released into non-immune population • Single case is considered a public health emergency • Can be aerosolized or contaminated items can be used to deploy this virus as a biological warfare agent

  39. Smallpox in Child

  40. SmallpoxClinical Features • Acute viral illness with severe skin lesions • Can have fever and aches for 2-4 days before rash • Rash most prominent on face and extremities Rash scabs in 1-2 weeks • Variola rash occurs all at once in contrast to varicella’s “crops” of lesions

  41. Smallpox • Mode of transmission: airborne, droplet and contact. • Person to person spread • Incubation Period = 7-17 days (ave. = 12 days) • Period of Communicability = Variola becomes infectious at onset of rash and continues to be infectious until their scabs fall off which is approximately 3 weeks

  42. SmallpoxPreventive Measures • STRICT ISOLATION • Negative air pressure room, doors must remain closed, verify ventilation • Mask, gown and glove for entry into room • Limit transport • Handle all surfaces and supplies as contaminated

  43. SmallpoxPreventive Measures • Smallpox vaccine • Vaccinia virus is used for vaccine(not smallpox virus) • Does not confer lifelong immunity • Must be given within 7 days post exposure to be effective

  44. Ricin • Causative agent: A biological toxin (poison) derived from the castor plant and castor oil. • Exposure routes: • inhalation (breathe it in) • percutaneous (injection or contact with skin, eyes, and mucous membranes) • ingestion (eat it!)

  45. RicinClinical Features • Weakness, fever, cough and fluid in lungs occur within 18 hours after inhalation(breathe in toxin) exposure • Progresses to severe breathing trouble and then death from hypoxemia within 36-72 hours • Diagnosis: signs and symptoms found in large number of a geographically clustered group and/or lab tests

  46. Ricin • Treatment: support patient, manage symptoms and keep comfortable • Prophylaxis: None available • Prevention • Protective mask to prevent inhalation • Standard Precautions • Weak hypochlorite solution (0.1% sodium hypochlorite) and/or soap and water can decontaminate skin surfaces
