Question

State the principle behind the eradication of polio

Answer 1

Eradication is the reduction of an infectious disease's prevalence in the global host population to zero.It is sometimes confused with elimination, which describes either the reduction of an infectious disease's prevalence in a regional population to zero, or the reduction of the global prevalence to a negligible amount. Further confusion arises from the use of the term eradication to refer to the total removal of a given pathogen from an individual (also known as clearance of an infection), particularly in the context of HIV and certain other viruses where such cures are sought.

Answer 2

Answer:

Pulse-polio programme was started in India in December 1995, and its target was to eradicate polio by 2003. However, it is still prevalent in states like Uttar Pradesh, Bihar, etc. The main reason being this is that in few sections of the society, there is a misconception that polio vaccine makes children sterile. These people do not get their children vaccinated against polio and hence, the target of polio eradication is not achieved.
