title: Malaria in Colombia: retrospective glance during the past 40 years.
abstract: OBJECTIVE
  Describe and analyze the structural configuration of malaria in Colombia since 1960 to 2004 where the phenomena of persistence, resurgence and resistance as well as the main determinants associated to these phenomena.
  
  
  METHODS
  A comparative study of the history of malaria and its trend was conducted in Colombia since 1960-2004. Secondary and primary information about the frequency and spatial distribution of malaria was collected. The sub period were identified according to institutional transformation and malaria control strategies as well as the socioeconomic and sociopolitical conjuncture factors in the country.
  
  
  RESULTS
  The structural and situational analyses of malaria in Colombia shown a steadily increase in morbidity from an average API 2,19 x 1 000 in 1960-74 to 8,92 by 1994-2004. Since the middle 70's there has been a considerable reduction of mortality. The malaria case relation P. vivax vs. P. falciparum is 3 to 5, respectively. The Annual Positive Sample Rate increased during the same study periods from 3.96% to 29.93%. Unfortunately the Annual Blood Examination Rate-ABER decreased by fewer than 5%, instead of increase to minimum required for detection of malaria.
  
  
  CONCLUSIONS
  During the National Eradication Malaria Service the malaria decreased steadily by the first five years, unfortunately the disease present resurgence, persistence after the reduction of financial and technical support from international health agencies in the middle seventies. Nowadays, around 85% of the territory, mainly rural areas are endemic for malaria. In spite of the transformation of the health system and different strategies implemented against malaria, it continues being one of the priorities in the public health services of Colombia.
