Millions of people who earn their living on daily basis suffer a lot because of their condition of having no income and endless hardships.

Millions of people become Infected in a short time and thousands of people die.
Many centuries ago, millions of people wordwide died of cholera, plague, malaria, etc. before the vaccines and medicines for these anti-viral diseases were discovered. At one stage, such epidemics led to a decline in the population of the world.
