Raccoon variant rabies cases in Ohio contingency action zone.
Since 16 July 2004 when raccoon rabies virus variant was first detected west of the existing oral rabies vaccination zone, 117 animals have been confirmed positive with raccoon variant within the contingency action zone. In 2007, no cases were detected via the public health surveillance system, illustrating the need for enhanced rabies surveillance.

Contingency actions in Ohio, 2008.
A large-scale trap-vaccinate-release (TVR) operation was conducted near Cleveland, Ohio, in 2008 and resulted in the hand vaccination of 4,196 raccoons and the brainstem testing of 138 raccoons and 77 skunks. The TVR zone consisted of 185 cells (1 km2 in size) and was delineated from raccoon variant rabies cases confirmed in the Contingency Action ORV zone in 2007 (n = 19). In addition to TVR, oral rabies vaccine baits were distributed over the area as part of contingency actions in 2008.
