Mortality caused by venomous animals in Venezuela (2000-2009): A new epidemiological pattern.

Introduction

Injuries by venomous animals frequently occur in impoverished communities with limited access to health services. They are considered neglected diseases that stand out as important causes of morbidity and mortality in various countries, including Venezuela.

Objective

To assess mortalities resulting from contact with venomous animals in Venezuela from 2000 to 2009 (X20-X29 series). Materials and

Methods

The data were obtained from the annual mortality records of the Venezuelan Ministry of Health.

Results

From 2000-2009, 759 fatalities were recorded with the greatest number taking place in 2009. Snakebites (n=323; 42.6%) accounted for the largest percentage of envenomation-related deaths in that period, followed by hymenopteran stings (n=170; 22.4%), centipede bites (n=106; 14.0%), and scorpion stings (n=76; 10.0%). The median value of envenomation-related deaths per 100,000 inhabitants (period 2000-2009) was 0.285: 0.120 corresponded to snakebites, 0.065 to hymenopteran stings, 0.035 to centipede bites, and 0.025 to scorpion stings.

Conclusions

Taking into account previous records of animal envenomations in Venezuela, we provided evidence for a shift in the pattern of mortality. Deaths due to centipede bites have increased, making it the third leading cause of envenomation-related mortality in Venezuela. Scorpionism, on the other hand, has declined to the fourth most common cause of fatal envenomations in the country.
