Update: management of patients with suspected viral hemorrhagic fever--United States.

In 1988, CDC published guidelines for managing patients with suspected viral hemorrhagic fever (VHF) (1). Pending a comprehensive review of the 1988 guidelines, this notice provides interim recommendations that update the 1988 guidelines for healthcare settings in the United States. This update applies to four viruses that cause syndromes of VHF: Lassa, Marburg, Ebola, and Congo-Crimean hemorrhagic fever viruses; although the risk and/or mode of nosocomial transmission differs for each of these viruses, the limited data do not permit clear distinctions.
