I am looking for potential data-sets containing information on snakebite occurrence/envenoming's.

I would ideally like this data at a subnational level, i.e. at the specific location of occurrence (village/town/district), and with accompanying information on the snake species responsible.

I am particularly interested in Echis ocellatus and Bitis arietans spp data.

Additionally, any useful links to databases on species occurrence for the above species would be greatly appreciated. I am aware of the site gbif (http://www.gbif.org/), but was wondering if there's any reptile specific repositories with an abundance of records for my species of interest.

Much appreciated!
