Question

Which of the following diseases has been eradicated from India?
A. Polio
B. Leprosy
C. Measles
D. Smallpox

Answer 1

Hint: The government takes various steps to prevent the spread of the disease and thus with proper preventive measures is able to completely eradicate the diseases from the country.

Complete answer:
The eradication of smallpox from the country was one of the achievements of the government. It was the only infectious disease which has been completely eradicated. Edward Jenner was the one developed vaccine for smallpox. The death ratio was very high due to this disease.
Smallpox was found to be one of the serious infectious diseases which were caused by the variola virus. It was a contagious disease which means that it can spread easily from one person to another person. People who suffered from smallpox had a fever and then distinctive, progressive skin rashes can be seen.
The people suffering with smallpox can recover mostly but it has been seen that about 3 out of every 10 people who suffered with the disease died. Many survivors of the smallpox have permanent scars which can be seen prominently over large areas of their body, especially their faces. This disease was so dangerous that some people even became blind.
Only the eradication of the disease was possible because of the development of the vaccine and thus smallpox was eradicated. After 1977, no cases of smallpox have happened. The last natural outbreak of the infectious disease was seen in the United States which occurred in 1949.

So, the correct answer is (D).

Note: Polio, leprosy and measles are still present in the human population and the vaccines are given at a very early age to prevent the occurrence of these diseases.
