ABSTRACT
The current surveillance model used by the Malaria Control Program in a Mexican state was analyzed using a systematic evaluation of the model ("PAATI" programs, actions, activities, tasks and inputs) through a diagrammatic evaluation of all the components in the process. The actions, activities tasks and inputs of this surveillance model (based on active and passive malaria case detection using tick blood smears examination), as well as those of an innovative alternative model (based on passive malaria case detection using immunodiagnostic strips, with an overall sensitivity of 93.3% and specificity of 99.5%) were identified and evaluated. It was documented that although the same actions are carried out in both models, many more activities are necessary with more tasks and inputs (traditional: 19 activities and 55 tasks, alternative: 13 activities and 32 tasks) in the current one. Adjusting to a population of 10,000 inhabitants, 1000 prospective cases and 2 years of surveillance, the cost of diagnosing and treating one malaria case was of 8.97 US dollars in this model and of 6.34 US dollars in the alternative one.
