Biological attack is a term that refers to the deliberate release of microorganisms or toxins that result in sickness and death of humans, animals, or plants. Synonyms include bioattack, bioterrorism, germ warfare, and biological warfare. A bioattack can involve the use of biological agents such as bacteria, viruses, fungi, or toxins that are harmful to living organisms. Biological agents can be spread through air, water, or food, or through direct contact with infected individuals. In recent times, the threat of a biological attack has increased, with several countries and terrorist organizations actively pursuing the development of biological weapons. Effective measures to prevent and respond to biological attacks are crucial in mitigating their impact on human life.
