A rabid beaver attacked children at Lake Henry in Mahwah, New Jersey, during the weekend preceding May 7 [1], [2].

The incident highlights the unpredictable danger of wildlife rabies in public recreational areas and the critical need for immediate medical intervention following animal bites.

An eight-year-old boy was hospitalized after the encounter [1], [4]. While some reports focus on the eight-year-old, other accounts state that multiple people were bitten, including a nine-year-old child [3], [5]. The attacks occurred while the children were at the lake in the local park [1], [2].

Laboratory testing later confirmed the beaver had a positive rabies test [2]. Because rabies is a fatal disease if not treated promptly, health officials in Mahwah Township issued warnings to residents to remain vigilant around wildlife [3].

Local authorities advised the public to avoid contact with animals displaying unusual behavior. Common rabies carriers in the region include bats, coyotes, foxes, raccoons, and skunks [3]. The Mahwah Township Health Department said the importance of vaccination and medical treatment for anyone who may have been exposed to the animal is critical [3].

Emergency responders and health officials managed the scene and the subsequent testing of the animal. The hospitalization of the eight-year-old boy ensured he received necessary medical care following the bite [4].

This incident underscores the risk of zoonotic diseases in suburban parks where humans and wildlife frequently overlap. Because beavers are not the most common rabies vectors compared to raccoons or skunks, the attack serves as a reminder that any mammal displaying aggression or disorientation can be a carrier, necessitating rapid post-exposure prophylaxis to prevent fatality.
