Biological Threat

Biological agents are bacteria, virus or toxins that can kill or incapacitate people, livestock and crops. 

Delivery Methods: 

  • Aerosols:  Biological agents are dispersed into the air forming a fine mist that may drift for miles.  Inhaling the agent may cause disease in humans and animals 
  • Animals:   Insects and animals such as fleas, mice, flies, mosquitoes and livestock spread some diseases 
  • Food and water contamination: Some pathogenic organisms and toxins may persist in food and water supplies. Most microbes are killed, and toxins deactivated, by cooking food and boiling water for three minutes 
  • Person-to-person: A few infectious agents, such as smallpox, plague and the Lassa viruses can spread through human contact 

Precautions for Known or Suspected Exposure: 

  • Move away from the agent quickly 
  • Remove and bag contaminated clothes and items 
  • Wash with soap and water 
  • Contact public health authorities 
  • Monitor local broadcast media for emergency information and instructions 
  • Seek medical attention if symptoms appear – public health instructions may include avoiding others or quarantine
