    BackgroundThe immigrant populations from sub-Saharan and Maghreb countries are groups in high risk of contracting tuberculosis. An analysis is made of the prevalence of tuberculosis infection among one group of these immigrants in Ceuta for the purpose of finding possible differences in their incidental behavior according to the country or geographical region from which they came.MethodsA descriptive cross-sectional study of a sample of 2,223 immigrants (1979 males and 244 females) from different African countries (mainly Nigeria, Mali, Guinea-Bissau, Cameroon, Ghana, Sierra Leona, Democratic Republic of Congo and Liberia) at the Calamocarro refugee camp in Ceuta. A Mantoux intradermic reaction test was performed following the previously-established protocol, the data for three cut-off points being presented.ResultsThe immigrants came from 36 African countries, 89.0% being males and 11.0% females (p < 0.001), respectively averaging in age from 24.9 +/- 4.3 to 23.4 +/- 4.1. A reaction to the Mantoux text of 10 mm or more was found in 32.6%, that is 33.2% among males and 27.9% among females (p = 0.09). Solely 1.1% showing 5-10 mm hardening of probable vaccination-related cause. By geographical regions, the highest rates were found among immigrants from the Democratic Republic of Congo (65.1%) and Cameroon (48.4%), followed far behind by Nigeria (34.0%), Liberia (32.7%), Mauritania (29.1%), Sierra Leona (28.8%), Ivory Coast (27.8%), Guinea-Bissau (27.4%), Ghana (26.3%), Algeria (25.6%), Mali (24.1%) and the Republic of Guinea (20.9%) (p < 0.0001).ConclusionsThe immigrant population from central African countries shows a higher prevalence of tuberculosis infection, comprising a group at risk of contracting this disease. Therefore, it is of fundamental importance to implement specific programs to actively detect tuberculosis infection during their stay in our city, taking advantage of their being grouped together upon entry into our country, prior to their final emigration to localities throughout the mainland and subsequent mixing among the host country population.
