Sierra Leone is the worst affected Ebola country housing almost half of all cases. Since April 2003 Médecins Sans Frontières
(MSF) was managing a secondary level paediatric and obstetric emergency hospital near Bo Town, an economic hub in
Sierra Leone. Close collaboration existed with the Ministry of Health Disease Surveillance Officers prior to the outbreak. When
the first positive patient was confirmed in Bo, teams immediately started following up suspects and their contacts. Here we
describe the mode of transmission over time, the different geographical clusters, and the breakdown in surveillance coverage
in the district following the dramatic rise in case numbers. Program data were analyzed retrospectively from the 20th of June
until the 18th of October 2014. A total of 288 suspects were investigated, with 161 confirmed and 61 probable cases. On July
4th of the 35 (11%) confirmed/probable patients were admitted to an MSF Ebola Treatment Centre, whereas in October
this increased to 44% (24/55). Of all confirmed/probable cases, modes of transmission could be classified as funerals (37%),
unknown (30%), house hold (16%), contacts without further information (5%), hospital acquired (9%) and contact while
travelling/visiting family (3%). While in July, 11% of the confirmed/probable cases had an unknown mode of transmission,
this increased to 58% in October. Although preparedness was started before the first case arrived in Bo District, the control
over the situation was lost due to the magnitude of the outbreak and the shortage of human resources in the field to perform
surveillance related activities.


Veerle Hermans completed an MSc in Biology in 2007 in Ghent, followed by a Postgraduate in Tropical Biomedical Sciences and International Health at the Institute
of Tropical Medicine (ITM) in Antwerp. Staying as a scientific collaborator at the ITM, she resulted in 2 published articles in Malaria Journal. A passion for primates
motivated her to successfully complete a Master in Research on Primatology at Roehampton University in London in 2011. Between 2011 and 2013 periods of field
work for the Max Planck Institute for Evolutionary Anthropology (Leipzig), she alternated with medical writing for Janssen Research and Development (Beerse). In
April 2014, she started as a field epidemiologist for MSF Belgium, working in the Ebola response for 7 months in Sierra Leone and 2 months in Liberia.
