Biological Attacks

Biological warfare is a deliberate attack by releasing germs, toxins, or other biological substances that can kill or disable people, food supplies, and crops. Bacteria, viruses, and toxins are the three basic groups of biological agents likely to be used as weapons. These biological agents are spread through animals, food supply contamination, person-to-person contact, and spraying them into the air. 


Signs of a biological attack may not be immediately apparent when they happen. A biological attack can go undetected for hours, days, or possibly weeks, depending on the type. Local health care workers may detect a wave of unusual and similar illnesses, though evidence of an attack may be apparent in animals before humans. If the attack is known to be biological warfare, you will be alerted through your mobile device, television, or radio broadcast. 

  • Make sure you and your family are up to date with immunizations

  • Prepare an emergency supply kit

  • Create an emergency plan for you and your family

  • Consider installing a High-Efficiency Particulate Air (HEPA) filter in your furnace return duct, which will filter out most biological agents.

Prepare For an Attack
Biological Warfare Safety
  • Tune into radio, television, or the internet for official news regarding areas in danger, symptoms of the illness, and where to go for medical attention.

  • Cover your nose and mouth while in areas of risk.

  • If you have symptoms that match those related to the attack, seek emergency medical attention. 

  • If you have been in contact with a biological agent, remove your clothes and personal belongings. Follow instructions for what to do with contaminated items.

  • Pay attention to official instructions and alerts with how to proceed after a biological attack. Medical protocol for a biological attack varies depending on the type and scale of the agent.
