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 400 cases have been reported, including at least 300 deaths, in the country. The neighbouring countries, Liberia and Sierra Leone, have recorded a total of 600 cases (confirmed and suspected).

The map shows the distribution of Ebola outbreaks in the recent 3 decades and the home range of fruit bats (possible natural host of Ebola virus). Background colour of countries represents the Ebola subtype, with pie charts showing the proportion of deceased cases whereas their sizes indicate the total number of reported cases in the respective time period. Among subtypes, Ebola-Zaire has the highest geographic coverage, number of people infected and the longest time range. At the recent outbreak in Guinea, Ebola-Zaire subtype infection is reported for the first time in West Africa. Ebola virus can be transmitted through direct contacts with blood, secretions, other bodily fluid 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.

Data for the map were extracted from WHO and CDC.

Ebola haemorrhagic fever, a disease caused by Ebola virus, spreads through wildlife-to-human or from human to human. The main signs and symptoms include fever, intense weakness, muscle pain, headache and sore throat, followed by vomiting, diarrhoea, rash, impaired kidney and livery function. There can be internal and external bleeding. The time interval from infection to symptom onset (incubation period) is 2-21 days. There is no specific treatment available and only supportive therapy is indicated. The case fatality rate is as high as 90%.


How does it spread? 如何傳播?

Ebola virus spreads through direct contact with blood, secretions, other bodily fluid and organs of infected animals or human. Pteropodidae family of fruit bats is considered as possible natural host of Ebola virus.

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。相信果蝠(大蝙蝠科) 是原宿主。

Vaccine? Prevention? 如何預防?

There is no vaccine available for Ebola haemorrhagic fever. The only ways to prevent transmission include infection control in health-care settings, raising awareness of Ebola infection risk factors and personal preventive measures.
