Cluster of Ebola Cases Among Liberian and U.S. Health Care Workers in an Ebola Treatment Unit and Adjacent Hospital — Liberia, 2014 Joseph D. Forrester, MD, Jennifer Hunter, DrPH, Satish K. Pillai, MD, et al. MMWR 2014;63(Early Release):1-5 In July 2014, CDC assisted the Ministry of Health and Social Welfare of Liberia in investigating a cluster of five Ebola cases among U.S. and Liberian health care workers who became ill while working at an Ebola treatment unit, an adjacent general hospital, or both. This report summarizes their findings. No common source of exposure or chain of transmission was identified. However, multiple opportunities were identified for possible transmission of Ebola virus to health care workers, and none of those opportunities were found to be a previously unrecognized mode of transmission.
