Bioterrorism Readiness Plan Shands Hospital at the University of Florida 2001 Tokyo Train Station Aerial view of anthrax production facility Where and when will bioterrorism hit next? Biological Weapons????? Bioterrorism Readiness Planning Subcommittee Sub committee of Infection Prevention and Control Committee Chair: Kenneth Rand, MD Multidisciplinary Membership Multidisciplinary Membership Infection Control Staff Hospital Epidemiologist Physicians • Infectious Disease Physicians • Emergency Medicine Chief and other ER Physicians • Surgeons Emergency Department Nurse Manager Safety Director Public Relations Respiratory Care Laboratory Facilities Operations Public Health Administrator & other agencies Materials Management Administration 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 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 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 Bioterrorism Readiness Plan Basic 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.

Anthrax Clinical 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 Anthrax Preventive Measures Standard Precautions Antibiotic Therapy Ciprofloxacin Levofloxacin Ofloxacin Doxycycline Amoxicillin for exposed children Vaccination Botulism Botulism Clostridium botulism Present in soil and marine sediment Foodborne botulism most common disease Inhalation botulism may also occur Botulism Clinical 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 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 Botulism: Exposure Management Preventative Measures Vaccine Standard Precautions Prophylaxis and Post exposure immunization Botulinum antitoxin Patients may require mechanical ventilation 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 Life cycle of plague Plague Clinical Features Pneumonic Plague Fever, cough, chest pain Hemoptysis (Bloody sputum) Bubonic Plague - skin and tissue disease form 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 Plague Preventive 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 Last known person with smallpox in the world Public Health Quarantine Sign 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 Smallpox in Child Smallpox Clinical 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 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 Smallpox Preventive 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 Smallpox Preventive 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 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!) Ricin Clinical 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 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 Steps in Preparing for a Bioterrorism Event Know how to locate policy Review Executive Summary of Plan for inclusion in Disaster Manual Access Specific Departmental Policies ER Pharmacy Use Information Sheets for Patients and Public Learn about bioterrorism by completing module.
