Map shows the distribution of reported Cholera cases by country in Africa in the year 2007, expressed in graduated colours from yellow (low) to red (high). The blue coloured symbols in varying sizes represent the percentage national population with access to sanitation facilities.

The Democratic Republic of the Congo had the highest reported number of Cholera cases (28269) followed by Ethiopia (24121) and Republic of Angola (18422). It appears that access to sanitation goes contrary to cholera caseload. Ethiopia, for example, had the second lowest access to sanitation facilities amongst all African countries, at 8%, only after Lesotho, 6%. The percentage access for Congo is also low at 9%, while that for Angola is 16%.

Cholera is a waterborne infectious disease. Limitation of safe water supply and poor sanitation are the known risk factors.

地圖顯示二零零七年非洲的霍亂情況,以漸變顏色,顯示每個國家呈報個案由低(黃色)至高(紅色)的分佈。藍色的漸變圖示代表各國人口得到清潔食水資源設備的百份比。

在非洲,剛果民主共和國是錄得最多霍亂呈報個案的國家,達28269宗;其次是埃塞俄比亞,24121宗及安哥拉共和國,18422宗。一般而言,霍亂的發生和清潔水源成反比。埃塞俄比亞是非洲國家中水資源設備最少的榜末第二名,只有8%,位居萊索托之後,只有6%。剛果和安哥拉則分別是9%和16%。

霍亂是經水傳播的傳染病,最重要的風險因素是不安全供水及惡劣的水資源設備。
