Under national polio eradication programme, a case of acute flaccid paralysis is confirmed as polio by surveillance after how many days after the onset of paralysis?
**Core Concept**
The national polio eradication programme relies on surveillance of acute flaccid paralysis (AFP) cases to confirm polio. This involves collecting stool samples from suspected cases and testing for the presence of poliovirus. The timeframe for confirmation is crucial for initiating public health responses.
**Why the Correct Answer is Right**
The correct answer is based on the standard protocol for polio confirmation, which typically involves a 60-day follow-up period after the onset of paralysis. During this time, stool samples are collected and tested for poliovirus, and the patient's neurological status is monitored. If poliovirus is detected in the stool samples or if the patient's condition meets specific clinical criteria, the case is confirmed as polio.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is too short a timeframe for comprehensive testing and follow-up.
**Option B:** This option is also incorrect as it does not align with the standard 60-day follow-up period.
**Option D:** This option is incorrect because it exceeds the typical follow-up period for polio confirmation.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the surveillance and confirmation process for polio under the national polio eradication programme is highly time-sensitive and standardized to ensure accurate detection and response to potential polio cases.
**Correct Answer:** C. 60 days
