THE FOUNDATIONS OF THE PHYTOSANITARY EPIDEMIOLOGICAL SURVEILLANCE IN MEXICO

Abstract

Having a concept of epidemiological surveillance entails the consensus of the perceptions and applications that occur in the three health systems (human, animal and plant). Between the 1950s and 1960s, epidemiological surveillance was only perceived as an updated database of the main pests and diseases, it was even said that the information collected predicted a permanent state of alert since it should guarantee timely data on the distribution and spread of pathogens in hosts. By the 1970s, epidemiological surveillance was already conceptualized as a set of activities with the aim of timely recommending the appropriate and efficient measures that lead to the prevention and control
of the disease. However, the comprehensive conceptualization of epidemiological surveillance is
framed at the beginning of the XXI century as a "system of processes to detect changes and anomalies in populations" (of humans, animals or plants). If we start from this consensus, not only an official institution can determine or evaluate these changes, but it must involve scientific society and civil society in general.
