Exposure of US Travelers to Rabid Zebra, Kenya, 2011

To the Editor: Rabies is an acute progressive encephalitis caused by infection with a lyssavirus (genus Lyssavirus, family Rhabdoviridae) (1). Most human infections are caused by bites from rabid animals, but the virus also can be transmitted by contact of open wounds or mucous membranes with animal saliva (1,2). Prompt administration of postexposure prophylaxis (PEP) is recommended to prevent rabies (3). Canids are common sources of human exposures in many regions of Africa, Asia, and Latin America (4). However, all mammals are susceptible, including herbivores such as horses, cattle, and antelope (5–7).
