title: The Mexican HIV/AIDS surveillance system: 1986-2001.
abstract: OBJECTIVE
  The objective of this article is to provide a comprehensive overview of the evolution of the Mexican HIV/AIDS surveillance system between 1986 and 2001.
  
  
  METHODS
  All information was collected through an extensive literature search.
  
  
  METHODS
  Databases such as the Mexican National AIDS Programmes RIMSIDA (Registry of Mexican AIDS Research), MedLINE, PopLine, and AIDSLINE were used. Databases, keywords, and MeSH headings to search were discussed and agreed upon before and during the literature search.
  
  
  RESULTS
  Two hundred and twenty articles and conference abstracts were reviewed and showed that the Mexican surveillance system has undergone many adaptations. The HIV/AIDS surveillance system began in 1986, when the focus was on identifying AIDS cases. This period was followed by special studies among risk groups, and served as the basis for the sentinel surveillance system that was adopted in 1990. The system now requires HIV and AIDS case reporting as well as sentinel surveillance. Mexico has also carried out the piloting of the behavioural surveillance component of Second Generation Surveillance.
  
  
  CONCLUSIONS
  The Mexican experience illustrates how surveillance systems need to be dynamic in order to monitor trends in HIV over time. This review also demonstrates that middle-income countries can successfully implement surveillance systems. However, although Mexico has had many successes, a need exists to address issues that limit its ability to implement AIDS case and behavioural surveillance fully and consistently.
