The objective of this study was to elucidate the etiology and frequenc
y of deaths in the United States from encounters with animals. The num
ber of deaths from venomous and nonvenomous animals is reported annual
ly to the US Department of Health and Human Services and published in
Vital Statistics of the United States. This study is a survey of all a
nimal-related fatalities listed as E-codes 905-906 reported in the Vit
al Statistics of the United States from 1979 through 1990. Data were e
xtracted uniformly from the annual reports and analyzed using descript
ive statistics. From 1979 through 1990, there were 1882 animal-related
deaths in the United States. Venomous animals caused 718 deaths; nonv
enomous animals caused 1164 deaths. Most deaths occurred among white m
ales. The home site was the location of injury for the majority of dea
ths. The majority of venomous animal-related deaths were from hymenopt
era; ''other specified animal'' caused the majority of nonvenomous dea
ths. An annual average of 157 deaths from animal attacks occurred in t
he United States between 1979 and 1990. Both fatal and nonfatal animal
-related injuries are under-recognized public health hazards. Health c
are providers should educate their patients on exercising caution arou
nd animals, seeking medical care after an animal injury, carrying epin
ephrine kits if they have a history of systemic reactions to insect st
ings, and wearing helmets and other protective equipment when riding o
r working around large animals.
