Via ReliefWeb, WHO's latest DON: Ebola virus disease, West Africa (Situation as of 5 April 2014). This is a long and detailed update. Excerpt:
As at 4 April 2014, the Ministry of Health of Guinea has reported a cumulative total of 143 clinically compatible cases of Ebola virus disease (EVD), of which 54 are laboratory confirmed by PCR. The total number includes 86 deaths (CFR 60%).
New cases have been reported from Conakry, Guekedou and Macenta; 23 patients are currently in isolation units. The date of onset of the most recent laboratory confirmed case is 3 April.
The current number of clinical and confirmed cases and deaths by place of report is Conakry (18 cases, including 5 deaths), Guekedou (85 cases/59 deaths), Macenta (27 cases/14 deaths), Kissidougou (9 cases/5 deaths), and Dabola and Djingaraye combined (4 cases/3 deaths). Sixteen of the 18 clinical cases in Conakry have been laboratory confirmed for EVD.
There has been no increase in the number of affected health care workers (HCW) from the 14 reported previously, including 8 deaths; 11 of the affected HCWs are laboratory confirmed cases. Sixteen of the 86 deaths overall are laboratory confirmed, 65 are classified as probable cases and 5 as suspected cases.
Case investigation and contact tracing are continuing, with 623 contacts requiring medical follow-up; this includes 74 new contacts identified on 3 April while 49 have been released from observation as they have remained well after the maximum incubation period for EVD of 21 days following the last exposure to a case.
Laboratory support for the investigation is being provided by Institut Pasteur Dakar, Senegal, and the mobile laboratory in Guekedou. Reference laboratory functions have been provided by Institut Pasteur Lyon, France, the Bernhard-Nocht Institute of Tropical Medicine Hamburg, Germany, and the Centre International de Recherche en Infectiologie (CIRI) laboratory in Lyon, France.
WHO, in collaboration with technical partners in the Global Outbreak Alert and Response Network (GOARN) has deployed field laboratory support, and experts in anthropology, epidemiology, logistics, clinical case management and infection prevention and control and outbreak coordination to support the response in Guinea.
