QID 109615 (Type "109615" in App Search)
A 35-year-old male nurse presents to the emergency room complaining of fever and malaise. He recently returned from a medical trip to Liberia to help with a deadly outbreak of a highly infectious disease. He reports severe generalized muscle pain, malaise, fatigue, and a sore throat. He has recently developed some difficulty breathing and a nonproductive cough. His past medical history is notable for asthma. He drinks alcohol socially and does not smoke. His temperature is 102.1°F (38.9°C), blood pressure is 115/70 mmHg, pulse is 115/min, and respirations are 24/min. On examination, a generalized maculopapular rash and bilateral conjunctival injection are noted. Laboratory testing reveals the presence of negative sense, singled-stranded linear genetic material with filaments of varying lengths. The pathogen responsible for this patient’s symptoms is most similar to which of the following?

Dengue virus

The patient in this vignette presents with hemorrhagic fever and laboratory findings suggestive of Ebola virus. Ebola virus and Marburg virus are members of the filoviridae family and are characterized by filamentous virions of varying lengths with (-) ssRNA.

Ebola virus is one of many viruses known to cause hemorrhagic fever. Ebola typically presents 2-21 days after exposure. Symptoms initially include headache, fever, and fatigue but rapidly progress to high fever, hematemesis, and altered mental status. Like Marburg virus, it is a enveloped, linear (-) ssRNA virus with a helical capsid. These viruses are part of the filoviridae family, named because of the filamentous shape of individual virions.

Incorrect Answers:
Answer 1: Dengue virus is an enveloped, icosahedral (+) ssRNA virus of the flavivirus family that is known to cause a painful fever (“break bone fever”) and/or hemorrhagic shock.

Answers 2-3: Lymphocytic choriomeningitis virus (LCMV) and Lassa fever virus are members of the arenaviridae family. These are circular (-) ssRNA viruses that cause hemorrhagic fever and meningitis, respectively.

Answer 4: Hantavirus is a circular (-) ssRNA virus of the bunyaviridae family. It primarily causes a deadly pulmonary syndrome.

Bullet Summary:
Ebola virus and Marburg virus are linear (-) ssRNA viruses from the filovirus family.
