N. Komar et al., Exposure of domestic mammals to West Nile virus during an outbreak of human encephalitis, New York City, 1999, EM INFECT D, 7(4), 2001, pp. 736-738
We evaluated West Nile (WN) virus seroprevalence in healthy horses, dogs, a
nd cats in New York City after an outbreak of human WN virus encephalitis i
n 1999. Two (3%) of 73 horses, 10 (5%) of 189 dogs, and none of 12 cats tes
ted positive for WN virus-neutralizing antibodies. Domestic mammals should
be evaluated as sentinels for local WN virus activity and predictors of the
infection in humans.
