5 Diseases That Have Been Eradicated
Human beings have suffered from many diseases throughout history but with the advancement of science, man has been able to defeat these diseases. While some of these victories have been limited to finding effective treatment some victories have led to disease extinction.
Disease extinction or eradication is a scenario where a previously prevalent disease has no active cases and requires no further medical intervention. The world has fought against many such diseases and has won on some occasions.
How are Diseases Eradicated?
To eradicate diseases a comprehensive action plan is required which focuses on prevention, treatment, testing, awareness and eliminating the chances of the disease spreading.
These efforts are led by governments with international aid. The World Health organization devises a plan to eradicate diseases.

India runs comprehensive diseases management programs some of which have been successful in the past. There are many more programs currently running to control other diseases. The following diseases have been eradicated from India:
