Detection of rotavirus using ELISA in sewage samples from two WWTPs (n = 96)

WWTP	Influent system	Effluent system	Total	Removal efficiency†
North	19* (32.7)**	15* (25.2)**	34* (57.9)**	21.05
South	15* (25.2)**	10* (16.9)**	25* (42.1)**	33.33
Total	34* (57.9)**	25* (42.1)**	59* (100)**	26.47

*The number of rotavirus positive samples

**The percent of rotavirus positive samples

^†The removal efficiency = (The number of rotavirus positive in influent samples) − (The number of rotavirus positive in effluent samples) ∕ The number of rotavirus positive in influent samples × 100
