  1. aApp-A and App-B are the predictive approaches used in the study. App-A predicted the onset of the high transmission season in 2019 using median rainfall data and median lag data for the 2014–2018 period. App-B predicted the onset of the high transmission season in 2019 using rainfall data for 2019 and median lag data for the 2014–2018 period
