Map shows the home locations of patients presenting with shortness of breath at the emergency room of a hospital in Hong Kong over a three-month observation period. Though symptomatically similar, the geographic distribution of asthma (white circles and white bars) and chronic obstructive airway disease (COAD) (purple circles and purple bars) patients varied considerably. COAD is a chronic condition affecting older people. It is therefore not surprising that their locations often overlapped those of homes for elderly people (shown as houses in navy blue). In some cases, COAD and asthma co-existed (white circles with thick purple boundaries), which may suggest the same triggering factor for breathless attacks in the environment.

Data were extracted from the dataset of a pilot study on fever surveillance conducted at the Alice Ho Miu Ling Nethersole Hospital in Tai Po District in Hong Kong between September and December 2005. The light green areas are DCCAs (District Council Constituency Areas) in central Tai Po where most people in the District live.

地圖顯示氣喘病人的居所分佈。在一段長三個月的觀察期內，地圖中的氣喘病人曾經到過香港一所醫院的急症室求診。哮喘(白色圖形)和慢性阻塞性肺病(紫色圖形)同樣令病者產生氣促現象，但地理位置差異頗大。慢性阻塞性肺病影響老年人，以致某些病者地點和老人院(籃色小屋)互疊。此外，一些地方同時發生兩種病（白色圖形，紫色邊），反映了潛在的環境因素，可能令兩種氣喘發作。

地圖數據源自二零零五年九月至十二月期間，在香港大埔區雅麗氏何妙齡那打素醫院進行的一項發燒監測研究。地圖中央淺綠色地帶是較多大埔區居民居住的區議會選區。
