Although Mexico has well over 100 veterinary laboratoties (Patología Animal) scattered throughout the Republic, but little contact indeed with labs of the Secretaría de Salud Pública, because veterinary work is under a different department: the Secretaría de Agricultura. The lack of a sentinel warning system, and the fault of immunological reagents make virus and other pathogen identifications impossibe. Many viral tasks can only be performed in the public health labs in Cuernavaca, Morelos near Mexico City.
