The mortality rate for patients with Ebola virus disease (EVD) in West Africa is approximately 65% [1]. There are no published figures for high-resource settings, but media sources and individual case reports suggest it is much lower and approaches 0% for those who receive this level of care from the beginning of their illness.

In their article “Ebola Viral Disease: Experience and Decision Making for the First Cases outside of Africa,” David Stephens and colleagues give insight into the care that can be provided when available resources are not the limiting factor [2]. They describe the decision to open the Serious Communicable Diseases Unit (SCDU) of Emory University Hospital (EUH) when two United States patients contracted EVD while working in West Africa. Using a large specialist team, they provided high-quality care in a safe working environment and disseminated their knowledge and experience widely.....

To the Editor: By December 31, 2014, the Ebola epidemic in West Africa had resulted in treatment of 10 Ebola case-patients in the United States; a maximum of 4 patients received treatment at any one time (1). Four of these 10 persons became clinically ill in the United States (2 infected outside the United States and 2 infected in the United States), and 6 were clinically ill persons medically evacuated from West Africa (Technical Appendix 1[PDF - 228 KB - 8 pages] Table 6).

Researchers found that the World Health Organization (WHO) Ebola case definition has a specificity of only 31.5%, and they noted that 9% of Ebola patients reported neither a fever nor any Ebola risk exposure, calling into question WHO norms, according to a large study yesterday in The Lancet Infectious Diseases.

Researchers from Britain and Sierra Leone analyzed data on 850 suspected and 724 lab-confirmed Ebola patients who presented to the holding unit of Connaught Hospital in Freetown from May 29 to Dec 8, 2014. Fever or history of fever (n=599, 83%), intense fatigue or weakness (495, 68%), vomiting or nausea (365, 50%), and diarrhea (294, 41%) were the most common presenting symptoms in suspected cases.

Based on data from these patients, the investigators found the sensitivity of the WHO case definition to be 79.7%, which means about 20% of true Ebola cases would be missed (false-negatives). They found the specificity of the case definition to be 31.5%, which means 68.5% of patients who would be selected for admission would not actually have Ebola virus disease (false-positives).

The number of new Ebola cases in Guinea and Sierra Leone declined a bit last week, with much of the disease activity centered in the two capital cities for the second week in a row, the World Health Organization (WHO) said in its weekly epidemiologic update today.

Tests confirmed 26 Ebola cases among the two countries, 22 in Guinea and 4 in Sierra Leone. The total is down from 30 reported the previous week, but progress against the disease has been stagnant over the past several weeks, hovering around 25 to 30 cases. Officials, however, said they saw more hopeful signs in contact tracing.

No new cases were reported in Liberia.

Overall, the total in the three countries has reached 27,705 confirmed, probable, and suspected cases, including 11,269 deaths, according to the WHO.
