The Ministry of Health (MOH) of Guinea has reported a cumulative total of 231 clinical cases of Ebola virus disease (EVD), including 155 deaths, according to a World Health Organization (WHO) update today.
There have been 5 new probable cases and 5 new deaths among the probable cases of EVD since the last report (currently 49 cases, including 39 deaths). In addition, 55 cases (34 deaths) are classified as suspected cases.
The geographical distribution of clinical cases of EVD since the beginning of the outbreak is: Conakry (53 cases, including 24 deaths), Guekedou (145/105), Macenta (22/16), Kissidougou (6/5), Dabola (4/4) and Djingaraye(1/1). There have been no new cases of EVD in Kissidougou since 1 April and in Macenta since 9 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 (72/50); Macenta (13/10); Kissidougou (1/1); and Dabola (1/1). The analysis of the epidemiological data during the last 3 weeks shows that the number of new cases is decreasing in Guekedou.
The numbers of cases and contacts remain subject to change due to consolidation of case, contact and laboratory data, enhanced surveillance activities and contact tracing activities. The recent introduction of ebolavirus serology to test PCR negative clinical cases is also likely to change the final number of laboratory confirmed cases.
As the incubation period for EVD can be up to 3 weeks, it is likely that the Guinean health authorities will report new cases in the coming weeks and additional suspected cases may also be identified in neighbouring countries.
