Risks to infants on Guam from bites of the brown tree snake (Boiga irregularis).

The brown tree snake, Boiga irregularis, is abundant on Guam and commonly invades human habitations. Data on emergency room visits on Guam document a high frequency of snakebites on Guam. Over 50% of the emergency room visits for snakebite involved children less than 4 years old. Records exist of 4 infants, 1, 2, 5, and 10 months old, who displayed significant symptoms after being bitten, while sleeping, by snakes. Two infants developed respiratory problems within a few hours and required medical treatment for asphyxiation. Lethargy, diminished sensory perceptions, drooping eyelids, swelling, discoloration, and bleb formation were variable in occurrence in the patients.
