| All samples | qPCR-MCA positive | ||
|---|---|---|---|
| Overall | Uganda | Ethiopia | |
| Microscopy positive | 139 | 121 | 18 |
| Microscopy negative | 84 | 39 | 45 |
| Microscopy sensitivity (%) | 62.3 | 75.6 | 28.6 |
| Samples with ≤ 2 MF total | qPCR-MCA positive | ||
| Overall | Uganda | Ethiopia | |
| Microscopy positive | 57 | 50 | 7 |
| Microscopy negative | 84 | 39 | 45 |
| Microscopy sensitivity (%) | 40.4 | 56.2 | 13.5 |
MF = microfilariae; qPCR-MCA = real-time polymerase chain reaction with melt curve analysis.
