Methods: Air-born pollen has been collected from 3 sites in Korean metropolitan areas from January, 2013 to December 2014. A trained researcher recorded the pollen count (grains/m3) on the stained slide with Calberla’s fuchsin. The data of Humulus japonicusis taken from ‘Sensitization Rate Survey in Korean Children’ by the Environmental Health Center for Allergic Rhinitis from March 2010 to July 2014.
Results: Humulus Japonicus pollen counts were 55.5%, the most common in summer flowering pollens in Korea. Sensitization rate to Humulus Japonicusis was 11.1%, the most common among causative pollens in children with allergic rhinitis.
Conclusions: To make the plan to take care of the patients sensitized to Humulus Japonicus, continuous monitoring the pollen level and sensitization rate to pollen should be needed.
