Global Atlas of Helminth Infection (GAHI)

Our goal is to provide reliable and updated maps and data describing helminth (worm) infection distribution that are essential to target treatment to populations in greatest need. In an attempt to address a paucity of geographical information on infection risk in a form that is accessible to policy makers and the managers of public health programmes, this Global Atlas of Helminth Infections has been developed. The goal is to build an open-access, global information resource on the distribution of helminthic NTDs: soil-transmitted helminths (STH), schistosomiasis and lymphatic filariasis.  

We aim to:  

  • Collate in a single, open-access database all available information on the prevalence of STH, schistosomiasis and lymphatic filariasis  
  • Describe the global distribution of these infections
  • Provide an information resource to guide control efforts  
  • Highlight areas where further surveys are required.  

Our maps are possible thanks to the generous contribution of data and support from various individuals and institutions worldwide.
