Write answer in between .Q:A 30-year-old forest landscape specialist is brought to the emergency department with hematemesis and confusion. One week ago, she was diagnosed with influenza when she had fevers, severe headaches, myalgias, hip and shoulder pain, and a maculopapular rash. After a day of relative remission, she developed abdominal pain, vomiting, and diarrhea. A single episode of hematemesis occurred prior to admission. Two weeks ago she visited rainforests and caves in western Africa where she had direct contact with animals, including apes. She has no history of serious illnesses or use of medications. She is restless and her temperature is 38.0C 100.4F; pulse, 95min; respirations, 20min; and supine and upright blood pressure, 13070 mm Hg and 10065 mm Hg, respectively. Conjunctival suffusion is seen. Ecchymoses are observed on the lower extremities. She is bleeding from one of her intravenous lines. The peripheral blood smear is negative for organisms. The laboratory studies show the following:Hemoglobin 10 gdLLeukocyte count 1,000mm3Segmented neutrophils 65Lymphocytes 20Platelet count 50,000mm3Partial thromboplastin time activated 60 secondsProthrombin time 25 secondsFibrin split products positiveSerum Alanine aminotransferase ALT 85 ULAspartate aminotransferase AST 120 ULγ-Glutamyltransferase GGT 83 UL N 550 ULCreatinine 2 mgdLWhich of the following is the most likely causal pathogen?? A: Ebola virus, B: Babesia microti, C: Plasmodium falciparum, D: Yersinia pestis, E: Zika virus,  <response>: Based on the information provided in the question stem, this appears to be a case of viral hemorrhagic fever likely acquired during the patients recent travel to rainforests and caves in western Africa. The symptoms of fever, headaches, myalgias, rash, abdominal pain, vomiting, diarrhea, hematemesis, ecchymoses, thrombocytopenia, coagulopathy, and transaminitis are all consistent with viral hemorrhagic fever. The main options for causal pathogens based on the geographic location are Ebola virus, Lassa fever virus, Marburg virus, and Crimean-Congo hemorrhagic fever virus. Babesia, Plasmodium, and Yersinia are unlikely given the clinical presentation. Zika would not cause this degree of hemorrhage. Therefore, Ebola virus is the most likely diagnosis.A: Ebola virus
