(2008). The Global Burden of Snakebite: "A Literature Analysis and Modelling Based on Regional Estimates of Envenoming and Deaths." Please visit the source here Death rate by is by venomous snake or reptile per 100,000 population. To obtain this data, the researchers systematically searched scientific literature for publications on snakebites and deaths from snakebites and extracted data on snakebite deaths in individual countries from the World Health Organization (WHO) mortality database. They also contacted Ministries of Health, National Poison Centers, and snakebite experts for unpublished information (“grey” literature) on snakebites. Together, these three approaches provided data on the number of snakebite envenomings and deaths for 135 and 162 countries, respectively.
