---|---|---|---|---|---|---|---|---|---|---|
Reported AFP cases, No. | 105 | 104 | 130 | 127 | 120 | 118 | 133 | 154 | 125 | N/A |
Confirmed polio cases, No. | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 3 (cVDPV1–2, VAPP–1) | 0 | 0 |
Polio-compatible cases, No. | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Non-polio AFP rate | 1.67 | 1.70 | 2.10 | 2.05 | 2.01 | 2.09 | 2.18 | 2.67 | 1.97 | ≥1.0b |
AFP surveillance indexc | 0.92 | 0.81 | 0.94 | 0.94 | 0.83 | 0.92 | 0.86 | 0.84 | 0.68 | ≥0.8 |
AFP cases with 2 adequate stool specimens, %d | 95.6 | 86.6 | 94.4 | 93.9 | 87.5 | 94.4 | 89.1 | 86.3 | 82.7 | ≥80% |
2016 data are preliminary, as reported by week 35 2016; non-polio AFP rates and surveillance index for 2016 are annualized.
The target for non-polio AFP rate 2.0/100,000 applies to countries at high risk of poliovirus spread and 3.0/100,000 to countries with active polio outbreak.
Non-polio AFP rate up to 1.0 multiplied by the proportion of cases with stool specimen.
Per cent of AFP cases with 2 stool specimens collected 24–48 h apart within 14 days of onset.
