Title of the paper: Modeling the Interruption of the Transmission of Soil-Transmitted Helminths Infections in Kenya: Modeling Deworming,Water, and Sanitation Impacts


Authors: Collins Okoyo*, Graham Medley, Charles Mwandawiro and Nelson Onyango


Kenya is part of the sub-Sahara Africa, which is endemic with Soil-Transmitted Helminths (STH). However control intervention such as Mass Drug Administration has been carried out for five years and the disease still persist in the population. Hence, the authors developed and analyzed an age structured mathematical model to predict the elimination period (i.e., time taken to interrupt STH transmission) of these infections in Kenya. The study utilized a deterministic age structured model of the STH population dynamics under a regular treatment program. The model was applied to three main age groups: pre-school age children (2–4 years), school age children (5–14 years), and adult populations (≥15 years) and compared the impact of two interventions mass drug administration (MDA) and water sanitation and hygiene (WASH) on worm burden and elimination period. It was observed that complementation of MDA with WASH at an optimal (95%) coverage level was most effective. These results are important to the Kenyan STH control program as it will guide the recently launched Breaking Transmission Strategy.
