Non-polio AFP rates serve as an indicator of which aspect of polio programs?

Explanation:
Non-polio AFP rates measure how sensitive the polio surveillance system is. They reflect how effectively AFP cases are detected and investigated, regardless of the actual cause. If the system is strong and actively looking for cases, you’ll identify more non-polio AFP per 100,000 children under 15, which shows good surveillance sensitivity. If the rate is too low, it can indicate under-detection and weaker surveillance, meaning poliovirus cases could be missed. This is not a direct measure of polio incidence, since many AFP cases are caused by conditions other than polio. It also doesn’t assess vaccine quality, which is about immunization programs and vaccine handling, or community engagement, which relates to how communities participate in vaccination efforts.
