Mortality due to mass Hymenoptera attacks: A serious but underrecognized public health problem in a mountainous state of India

Abstract

Most deaths related to Hymenoptera are a result of immediate hypersensitivity reactions causing anaphylaxis to one or few stings. However, if the patient is exposed to a large quantity of the venom due to mass/multiple stings, massive envenomation can cause death in nonallergic individuals. Thirty-nine cases of acute kidney injury (AKI) who followed mass attacks by Hymenoptera were seen over 15 years, with a reference period between 2003 and 2017. AKI was severe; most (85%) of them required dialysis and one-third died. Mass attacks by Hymenoptera have become a serious public health problem in tropics. There is no antivenom, and treatment in such cases is supportive. Early hospitalization is vital to reduce morbidity and mortality.
