title: The role of some risk factors of exposure to malaria in determining the outcome of the immunofluorescent antibody test in an urban population.
abstract: Data obtained previously were analysed to assess the relative importance of variables which relate to the risk of exposure to malaria in explaining the level of indirect fluorescent antibody (IFAT) reactions observed among the urban study population. In the analysis specific activities, notably travelling out of the main towns, season when out of the main towns, length of period since having been out of the main towns, and history of having had malaria in the last year, were of help in predicting the level of IFAT reaction. Sensitivity and specificity values of history of malaria, history of having been out of the main towns, and serological results were higher in older people in both periods and were highest in the March-April 1985 survey period.
