Question

Why are polio drops not given to a person suffering from diarrhoea?

Answer 1

In diarrhea, gut motility is increased. Whatever is ingested, comes out quicker.

Polio drops contain attenuated polio virus. Once given, a large proportion of this viral dose stays in intestine and proliferates to show it’s effect.

If given during diarrhea, most of it will be thrown out resulting in to lesser efficacy. For this very reason we wait till diarrhea is over.
