Humans

-When a virus emerges, a pandemic is likely to occur. Because the virus is new, the human population has little to no immunity against it. Before long, the virus can spread from person to person worldwide.

-Because pandemics are noble, it is often difficult to discover a cure for the illness before too many people fall victim to the disease and die within a short period.

-The pace that the disease spreads at is so overwhelming that the people in different states and regions can likely die from the diseases if the proper medications are unavailable to their advantage.

-For example, the Black Plague stole the lives of nearly one fourth and/or twenty-five million people who live in Europe. Polio paralyzed children and adults, one after another until a vaccine was discovered early enough to stop the paralysis in the 1950s.
