title: Incidence of pollinosis in the city of A Coruña: correlation with aerobiological data.
abstract: An atmospheric pollen count was carried out in the city of A Coruña during 1999 using two pollen traps located at two different points in the city. A total number of 6979 and 3536 pollen grains, respectively, were identified, the majority during the Spring and Summer. Further, patients living near the pollen traps were selected from among those diagnosed as suffering from respiratory allergies by the Allergy Department of A Coruña's Juan Canalejo Hospital. The patients had at least one positive skin test for some pollen type, had not received immunotherapy in the last year, and were willing to fill in a symptoms booklet during the study period. The results obtained reveal the pollen types that produce the greatest number of skin sensitization cases (Poaceae, Plantago, Chenopodium and Parietaria), with a positive correlation between the atmospheric pollen concentration of such taxa and the frequency of allergy symptoms. This has enabled the setting of pollen values, above which A Coruña's inhabitants are considered to be at risk.
