West Africa is experiencing the largest Ebola virus disease (Ebola) epidemic in
recorded history. Health care workers (HCWs) are at increased risk for Ebola. In
Liberia, as of August 14, 2014, a total of 810 cases of Ebola had been reported,
including 10 clusters of Ebola cases among HCWs working in facilities that were
not Ebola treatment units (non-ETUs). The Liberian Ministry of Health and Social
Welfare and CDC investigated these clusters by reviewing surveillance data,
interviewing county health officials, HCWs, and contact tracers, and visiting
health care facilities. Ninety-seven cases of Ebola (12% of the estimated total)
were identified among HCWs; 62 HCW cases (64%) were part of 10 distinct clusters
in non-ETU health care facilities, primarily hospitals. Early recognition and
diagnosis of Ebola in patients who were the likely source of introduction to the
HCWs (i.e., source patients) was missed in four clusters. Inconsistent
recognition and triage of cases of Ebola, overcrowding, limitations in layout of
physical spaces, lack of training in the use of and adequate supply of personal
protective equipment (PPE), and limited supervision to ensure consistent
adherence to infection control practices all were observed. Improving infection
control infrastructure in non-ETUs is essential for protecting HCWs. Since
August, the Liberian Ministry of Health and Social Welfare with a consortium of
partners have undertaken collaborative efforts to strengthen infection control
infrastructure in non-ETU health facilities.
