The objective of this paper is to present the methodology and applicability of serological surveys. Problems related to seroepidemiological surveys in immigrant population are also discussed. Seroepideniological surveys should be developed in representative samples of the population, determining the sample size taking into account the sample error and precision that should be obtained for population parameters. It is necessary to develop an adequate questionnaire to collect sociodemographical and medical information from all participants. Serological tests should sensitive and specific.
