A warning from the Baltimore County Health Department following last weekend's attacks on two swimmers by a rabid beaver. A 14-year-old boy and an adult woman were attacked north of Loch Raven Dam while swimming in the reservoir. "The boy was rescued by his mother. The female swimmer was rescued by her husband and a good Samaritan. In this instance, the 50-pound beaver was killed with a rock. It tested positive for rabies," Rabies Coordinator Gary Thompson tells Richard Sher. The Baltimore County Health Department reminds you to avoid contact with wildlife if possible, keep your pets up to date on their rabies shots and remember that swimming is not allowed in any drinking water reservoirs.
