Seroepidemiological investigations have been carried out in Switzerland since 1983.
The immune system has the task of protecting against serious infectious diseases. Allergies mean an excessive, harmful reaction. Protective and pathogenic immune reactions can be detected in the blood (serologically). The working group coordinates, for example, studies of exposure (pollen load) with epidemiological methods, e.g. frequency of sensitisation to molecular allergens.
