RESUMEN
We gathered and analyzed date on respiratory diseases suffered by Japanese adults treated in Ram Hospital in Chiang Mai and Subang Jaya Medical Center in Kuala Lumpur. In both hospitals, the percentages of patients undergoing treatment for respiratory diseases was the greatest. Of these, relatively mild symptoms such as upper respiratory tract infection account for the majority of the diseases, but also included are instances of lower respiratory tract infection or chronic respiratory diseases such as chronic sinusitis and COPD⁄bronchial asthma. In Kuala Lumpur, we conducted a questionnaire-based survey targeted on Japanese people living there, in order to detemine the currnt status of respiratory deseases. The date showed that many Japanese had symptoms of respiratory diseases and felt that air pollution was serious. <BR>It is important for Japanese people living in Asia to be aware of preventative measures to prevent respiratory diseases, such as those caused by air pollution and infection.
