Jw. Krebs et al., RABIES SURVEILLANCE IN THE UNITED-STATES DURING 1995, Journal of the American Veterinary Medical Association, 209(12), 1996, pp. 2031-2044
In 1995, 49 states, the District of Columbia, and Puerto Rico reported
7,877 cases of rabies in nonhuman animals and 4 cases in human beings
to the Centers for Disease Control and Prevention. Nearly 92% (7,247
cases) were wild animals, whereas 8% (630 cases) were domestic species
. The total number of reported cases decreased 4.2% from that of 1994
(8,230 cases). Most of the decline was the result of 17.1% fewer repor
ted cases of rabies in raccoons in areas of the Northeast, where rabie
s is now enzootic rather than epizootic. Exceptions to this decline we
re detected in states where the virus has only recently entered raccoo
n populations or where ongoing epizootics persist. States experiencing
increasing epizootic activity associated with this variant include Ma
ine (3 cases in 1993 to 101 cases in 1995), North Carolina (9 cases in
1990 to 466 cases in 1995), Rhode Island (1 case in 1993 to 324 cases
in 1995), and Vermont (45 cases in 1993 to 179 cases in 1995). The ra
ccoon variant of the rabies virus is now present in Alabama, Pennsylva
nia, Vermont, West Virginia, and all Atlantic Seaboard stales from Flo
rida to Maine. in Ohio, this variant, last detected in 1992 as a singl
e case, was again detected in 1996. Epizootics of rabies in foxes in w
est central Texas and in dogs and coyotes in southern Texas attributab
le to canine variants continue, with this slate reporting 137 rabid fo
xes, 55 rabid dogs, and 80 of the 83 cases in coyotes during 1995. The
number of rabid bats (787) increased by almost 25%, with cases report
ed by 47 of the 48 contiguous stales. Nationally reported cases of rab
ies in cattle (136) and cats (288) increased by 22.5 and 79%, respecti
vely whereas cases in dogs (146) decreased by 4.6%, Cats continued to
be the domestic animal most frequently reported rabid. The cases of ra
bies reported in human beings were ail caused by viral variants associ
ated with bats. Eighteen states and Puerto Rico reported decreases in
rabies in animals in 1995, compared with 28 states and the District of
Columbia in 1994. Hawaii was the only state that did not report a cas
e of rabies in 1995.
