Transmission dynamics of schistosomiasis in Zimbabwe: A mathematical and GIS Approach

• Temperature and presence of water bodies are known to influence the transmission dynamics of schistosomiasis.
• In this work, effects of water bodies and temperature from 1950 to 2000 are considered in the model.
• With the aid of Geographic Information System (GIS), the reproduction number is mapped on the Zimbabwean country.

Temperature and presence of water bodies are known to influence the transmission dynamics of schistosomiasis. In this work, effects of water bodies (taken in context of rainfall patterns) and temperature from 1950 to 2000 are considered in the model. With the aid of Geographic Information System (GIS), the reproduction number is mapped on the Zimbabwean country. Results of the mapping show high reproduction numbers along the Lowveld and the Zambezi valley catchment area. High reproduction numbers suggest high levels of schistosomiasis. This result suggests more control efforts should be targeted in these areas with high reproduction numbers.
