15-year aeroallergen records. Their usefulness in Athens Olympics, 2004

About 5-25% of 16 000 athletes involved in preparation for the Athens 2004 Olympics may encounter respiratory allergy (asthma and rhinoconjunctivitis) triggered by exposure to aeroallergens (pollen and fungi spores).

Provide information about circulating aeroallergens in three Olympic cities and ensure safety for the allergic athletes who will visit Greece from January to September 2004.

Aeroallergens were recorded using a Burkard volumetric trap. The most frequently implicated pollen (cypress, hazel, wall pellitory, plane, olive, grasses, goosefoot and mugwort) and fungi spores (Alternaria spp., Cladosporium spp.) are presented. These data derive from a 15-year database created by the Pulmonary Department, Thessaloniki, a 2-year database (University of Heraklion-Crete) and a 6-year database by the Pediatric Department, Athens. The above data and the current aeroallergen counts will be continuously announced by the mass media and Internet during the Athens 2004 Olympics.

Are expressed as: (A) Presentation (Graphs, Tables) of the fluctuation of mean daily values of pollen grains or fungi spores/m3. (B) Presentation (Tables) of the start, peak and end time of aeroallergen circulation. Peak pollen concentrations were observed between March and May (athletes preparation time). During the 2004 Olympics (August-September) relatively high concentrations of goosefoot, mugwort, Alternaria and Cladosporium will be observed. Aeroallergens circulate in Athens 10-15 days earlier than in Thessaloniki and 10 days later than in Heraklion.

The data presented in the study are expected to help allergic Olympic athletes achieve peak performance under prophylactic measures.
