Summary

Snakebite causes approximately 138,000 deaths each year and non-fatal bites lead to considerable health burden, particularly in low-income tropical countries. Data on snakebite burden are lacking. Official data from health facilities are often either unavailable or underestimate cases, by excluding the many victims who do not attend formal health facilities; community surveys are useful for assessing burden, but they require significant resources to conduct. This study aims to understand both whether spatial analysis methods can help in assessing and predicting snakebite risk in different environments, and the value of current data collection methods for their contribution to this analysis approach. First, snakebite data already recorded in health facilities in Ghana and Rwanda will be extracted and analysed. Community surveys will be conducted in environmentally diverse areas of Ghana and Rwanda to collect information directly from randomly selected households about their experiences with snakebites. Using GPS to map household locations, geostatistical methods will be applied to the data to see if it can accurately predict areas at high risk of snakebite; the predictions will be used to generate risk maps. The study findings will build knowledge on geographical variation in snakebite risk and help develop an approach to mapping snakebite risk in sub-Saharan Africa.

The risk maps generated will be compared with data on the distribution of antivenoms in each country. This will show if antivenoms are available in the places that need them most and help ensure antivenom supplies are better allocated in the future. It will also help identify high-risk areas so health officials can advocate for resources and develop treatment and prevention programmes.
