Rabid goats at a North Carolina petting zoo and a diseased beaver attacking a Maryland boy have set the public on edge

Recent unusual incidents involving humans and rabid animals and a subsequent Centers for Disease Control and Prevention (CDC) advisory have prompted concerns about rabies, but it’s not clear if there has actually been an increase in cases of the deadly disease in the United States, experts say.

In recent months, rabid beavers have attacked three people in Maryland, and hundreds of people were exposed to goats with rabies at a petting zoo in North Carolina, according to news reports. The CDC issued a health advisory on 10 September “in response to recent reports of increases in human exposures to rabid or possibly rabid animals”.
