Average parasite intensity among infected children from stool samples
| State | Parasite | Mean* eggs per gram of stool (maximum)† | |
|---|---|---|---|
| 2013 | 2018 | ||
| Nasarawa | Ascaris lumbricoides | 782.4 (8,640) | 459.7 (7,332) |
| Hookworm | 162.0 (3,720) | 154.6 (6,240) | |
| Schistosoma mansoni | 96.4 (1,440) | 157.9 (1,200) | |
| Trichuris trichiura | 88.0 (216) | 32.0 (96) | |
| Plateau | A. lumbricoides | 202.0 (3,240) | 172.7 (1,200) |
| Hookworm | 450.3 (24,480) | 154.8 (2,796) | |
| S. mansoni | 454.1 (11,520) | 134.9 (2,316) | |
| T. trichiura | 174.9 (576) | 114.0 (192) | |
NB = thresholds for heavy-intensity infections were ≥ 400 eggs per gram (epg) of stool for S. mansoni, ≥ 50,000 for A. lumbricoides, ≥ 4,000 for hookworm, and ≥ 10,000 for T. trichiura.
*
Means are calculated on positive children only.
†
Average egg count per gram of stool was gathered through Kato-Katz technique and calculated by taking the average of two slide readings and multiplying it by 24.
