Abstract
Particularly in Japan, the number of individuals affected by cedar pollen allergy is increasing every year owing to continuous mass scattering of pollens and similar allergens. In the future, the number of affected individuals will increase and younger patients are expected. Since pollen dissemination is considerably affected by the terrain and climate change, information on the region can be used to establish antigen avoidance measures and prevent pollen exposure. Furthermore, providing pollen information together with the results of specific IgE antibody tests can help improve the quality of life (QOL) of sufferers. Thus, in order to grasp the actual cedar pollen situation, we performed measurements of airborne pollen count from 2012 to 2014 and considered the relationship between the contract number and the rate of positivity for the cedar-specific antibody, as determined by the tests conducted in the Institute. Pollen count has been suggested to affect the contract number and positivity rate. Thus, it is important to take advantage of research and information specific to the region.
