Re-emergence of Ebola virus 伊波拉病毒的再現
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.
