Epidemiologic surveys of histoplasmin and paracoccidioidin sensitivity in Brazil

We report here the results obtained in epidemiologic surveys of histoplasmosis and paracoccidioidomycosis carried out in Brazil using the histoplasmin and paracoccidioidin delayed hypersensitivity skin tests. Most of these data have not been previously published in scientific journals and are now reported here in two tables respectively concerning histoplasmosis (88 surveys) and paracoccidioidomycosis (58 surveys). The guidelines to be followed in surveys of this nature are also commented upon.
