In the context of polio surveillance, 'Acute Flaccid Paralysis (AFP) surveillance' uses a minimum target rate. The WHO-recommended AFP surveillance target rate (non-polio AFP rate) is at least:

• A 1 per 100,000 children under 15 years per year
• B 2 per 100,000 children under 15 years per year ✓
• C 5 per 100,000 children under 15 years per year
• D 0.5 per 100,000 children under 15 years per year

Explanation

The WHO target for sensitive AFP surveillance for polio eradication requires detection of ≥ 2 non-polio AFP cases per 100,000 children under 15 years per year. This rate ensures the surveillance system is sensitive enough to detect true poliovirus-associated AFP if it occurred. Additional quality indicators include: stool adequacy rate ≥ 80% (two adequate stool specimens collected within 14 days of paralysis onset, stored correctly). India was certified polio-free in 2014 and continues AFP surveillance to prevent re-introduction.
