The formulation is largely derived from nature, but is capable of being cultivated to produce changes to make it more pathogenic, provide access to existing pharmaceutical resistance, or increase environmental spread. Bioterrorism, the word comes from bio- and terrorism. Bio- is a combined form meaning “life”, “living organism”, “biology”.

If humans overcoming the virus makes us proud, then the story of human use of viral guts leaves human shame. When humans began to gain great knowledge of disease-causing viruses and bacteria, villains also began to think of using viruses and bacteria as a tool to kill people. War breeds the evil of humanity, but also nurtures many evil tools. Used bacteria and viruses as weapons of war, although the International Convention on the Use of Viruses and Bacteria has been banned in war, but terrorists will not be bound.
