VIRUS</NYT_BRIEFINGS_TITLE><NYT_BRIEFINGS_SUMMTEXT> Mexico declared a state of
emergency regarding the mosquito-borne West Nile virus, calling it a severe risk
to its horse population and a growing threat to people. The virus was discovered
in Mexico on May 16 in a dead crow in Tabasco State. Mexico's animal health
authority said the disease had since spread to horses in the states of
Chihuahua, Tamaulipas, Coahuila, Veracruz, Tabasco, Quintana Roo and Yucatán. No
human deaths have been reported. The authorities have asked horse owners to
vaccinate their animals. </FONT></DIV>
