Central and South Asia is characterised by huge environmental variation and large socio-economic inequalities. These are reflected in the varied distribution of STH infections. Given the large populations involved, and the potential numbers at risk of infection and in need of treatment, there is clearly an urgent need for reliable, up-to-date distribution maps.
Here we provide maps of all available STH survey data from published and unpublished sources. Much of these data are only reported at a district or provincial level, and work is ongoing to generate predictive models for STH species in this region.
