Since March 2014, there has been an ongoing Ebola Haemorrhagic Fever (caused by Ebola virus) outbreak in Guinea in West Africa. By the end of July, more than 600 cases have been reported, including at least 400 deaths, in the country. The neighbouring countries, Liberia and Sierra Leone, have had faster epidemic growth than Guinea. Liberia has recorded above 1300 confirmed and suspected cases, including 690+ deaths. Sierra Leone has recorded at least 1000 cases, of which more than 400 died. At the end of July, Nigeria has its first reported cases, and the number of was more than 10 with almost half of them died within 1 month. The graphs show the cumulative number of reported cases in each respective country since March 2014.

The map shows the home range of fruit bats (possible natural host of Ebola virus). The background colour of countries on the map highlights the places which had Ebola outbreaks before 2014, with pie charts showing the proportion of deceased cases whereas their sizes indicate the total number of reported cases in the respective time period. Ebola virus can be transmitted through direct contacts with blood, secretions, other body fluids and organs of infected animals or human. Infection control in health-care settings and personal preventive measures are essential for controlling the spread of this deadly infection.

今年三月,西非國家畿內亞爆發伊波拉出血熱 (由伊波拉病毒引起的疾病),並持續至現在尚未完結。截止八月底,已經有超過600宗確診及懷疑個案,當中超過400人死亡。其鄰近國家利比利亞及塞拉利昂的確診及懷疑個案數目增長更快。利比利亞累積超過1300宗確診及懷疑個案,當中超過690人死亡。而塞拉利昂共有多於1000宗確診及懷疑個案,包括400多宗死亡。七月底尼日利亞也受波及,一個月內已有十多宗確診及懷疑個案,大約一半死亡。圖表顯示各地區自今年三月的伊波拉出血熱累積報告人數。

地圖顯示果蝠(相信是原宿主)棲息地的分佈,地區顏色代表2014年前伊波拉出血熱的爆發地區,餅圖表示死亡人數比例,大小則反映報告人數。伊波拉病毒可以通過接觸已受感染的動物及人的血液、體液和器官傳播。為預防此極高死亡率的疾病傳播,醫療機構感染控制及個人預防措施至關重要。
