    • Description:
      Travelers planning to conduct humanitarian work in areas where outbreaks of Ebola hemorrhagic fever and Marburg hemorrhagic fever are known to occur need to be familiar with how Ebola virus and Marburg virus are transmitted. These viruses are believed to be transmitted from an unknown animal host to humans. Humans can infect other humans through contact with blood or body fluids (e.g., saliva, urine). People who have close contact with a human or nonhuman primate infected with the virus are at risk. Such persons include laboratory or quarantine facility workers who handle nonhuman primates that have been associated with the disease. Hospital staff and family members who care for patients with the disease also are at risk if they do not use proper barrier nursing techniques. These precautions include wearing protective gowns, gloves, and masks, in addition to wearing eye protection (e.g., eye glasses) or a face shield. The likelihood of contracting any viral hemorrhagic fever (VHF), including Ebola or Marburg, is considered extremely low unless there has been travel to the affected area and direct contact with the blood or body fluids (e.g., saliva, urine) of symptomatic infected persons or animals, or objects that have been contaminated with body fluids. The cause of fever in persons who have traveled in areas where VHF is present is more likely to be a common infectious disease, but such persons should be evaluated by a health-care provider to be sure.
