How do biological disasters occur?

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/her system through a cut or wound, they can infect him/her. Even a few drops of the smallpox or plague virus could start an epidemic, killing thousands of people.
