Chiang Bor-luen, chairman of the Department of Pediatrics at National Taiwan University Hospital (NTUH), explains that the increase in allergies is a global phenomenon, but because of environmental differences, different allergies more commonly occur in different regions: the colder a region, the higher its incidence of eczema, while in hot and humid regions, asthma is more prevalent.
台大小兒部主任江伯倫指出，過敏性疾病增加是一種全球性趨勢，但因地理環境的不同，種類有所差異，整體來說，越寒冷的地方，異位性皮膚炎的比例越高；濕熱的地方，氣喘的比例越高。
