उत्तर
Biological disasters are caused by germs developed in laboratories and released in the air to kill a large number of people. When these microbes are inhaled by a person, or get absorbed in his system through a cut or wound, they can infect him. Example — Even a few drops of the smallpox or plague virus could start an epidemic, killing thousands of people.
