12 May 2014

Guinea

As of 18:00 on 10 May 2014, the Ministry of Health (MOH) of Guinea has reported a cumulative total of 233 clinical cases of Ebola Virus Disease (EVD), including 157 deaths. Since the last update of 9 May 2014, there have been no new cases confirmed by ebolavirus PCR and no new deaths bringing the total number of confirmed cases to 129, including 83 deaths.

There have been no change in the number of probable cases or deaths (49 cases, 40 deaths) and suspected cases or deaths (55 cases, 34 deaths). The geographical distribution of clinical cases of EVD since the beginning of the outbreak is as follows: Conakry (50 cases, including 24 deaths), Guekedou (149/106), Macenta (23/17), Kissidougou (6/5), Dabola (4/4) and Djingaraye (1/1).

There have been no new cases of EVD in Kissidougou since 1 April, Macenta since 9 April and Conakry since 26 April. In Djingaraye and Dabola, no new cases have been reported since the end of March 2014. The cumulative total of laboratory confirmed cases and deaths since the beginning of the outbreak is: Conakry (40 cases, including 20 deaths); Guekedou (74/51); Macenta (13/10); Kissidougou (1/1); and Dabola (1/1).

The numbers of cases remain subject to change due to reclassification and consolidation of cases and laboratory data, enhanced surveillance activities and contact tracing activities. Introduction of ebolavirus serology to test PCR negative clinical cases is also likely to change the final number of laboratory confirmed cases.

Liberia and Sierra Leone

There have been no new alerts in both Liberia and Sierra Leone. Preparations to host cross- border meeting with Ivory Coast and Sierra Leone are underway.

In Liberia, upon review and consolidation of data, the cumulative number of cases is 12 (6 confirmed, 2 probable and 4 suspected). There has been no change in number of deaths (11) and date of onset of the most recent confirmed or probable case (6 April 2014).
