Each pupil previously treated was retreated 6 or 7 months after the initial treatment in Ogun State, Nigeria.The implementation was based on the theoretical equation for time-prevalence: Y = G [1 -(1-X)N-R]. Using the Psuedo-Code of the MONRATE tool, the calculated monthly reinfection rates (X) for the LGAs were 1.6% in Ewekoro, 2.3% inOdeda, 2.3% in Ado-odo/Otta, 3.8% in Ogun Waterside and 4.2% in Obafemi/Owode. The mathematical mean of 'X'values in the study areas for Ogun State was 2.84. The calculated reinfection time (N months) for the LGAs varied suchas Ado-odo/Otta (12.7), Ogun Waterside (21.8), Obafemi/Owode (22.92), Odeda (25.45), and Ewekoro (25.9). The meanvalue for N in Ogun State was 21.75. The results obtained from MONRATE were compared with those obtained using themathematical equation and were found to be the same but MONRATE was faster in computation and more accurate. Itis concluded that MONRATE is a veritable tool that can be used in the execution of control programme involving masstreatment against A. lumbricoides.<br><br> <b>Keywords</b>: MONRATE, <i>Ascaris lumbricoides</i>, re-infection rate, Nigeria<br><br><i>Tanzania Health Research Bulletin</i> Vol. 8 (2) 2006: pp. 75-79 ER -
