What is the virus that is viral fever of humans and primates and that Triazavirin could have a potential application?
Ebola virus disease
Title: Marburg virus disease
Passage: Marburg virus disease (MVD; formerly Marburg hemorrhagic fever) is a severe illness of humans and non-human primates caused by either of the two marburgviruses, Marburg virus (MARV) and Ravn virus (RAVV).  MVD is a viral hemorrhagic fever (VHF), and the clinical symptoms are indistinguishable from Ebola virus disease (EVD).
Title: Triazavirin
Passage: Triazavirin (TZV) is a broad-spectrum antiviral drug developed in Russia through a joint effort of Ural Federal University, Russian Academy of Sciences, Ural Center for Biopharma Technologies and Medsintez Pharmaceutical.  It has an azoloazine base structure, which represents a new structural class of non-nucleoside antiviral drugs.  It was originally developed as a potential treatment for pandemic influenza strains such as H5N1, and most of the testing that has been done has focused on its anti-influenza activity.  However triazavirin has also been found to have antiviral activity against a number of other viruses including tick-borne encephalitis, and is also being investigated for potential application against Lassa fever and Ebola virus disease.
Title: Ebola virus disease
Passage: Ebola virus disease (EVD), also known as Ebola hemorrhagic fever (EHF) or simply Ebola, is a viral hemorrhagic fever of humans and other primates caused by ebolaviruses.  Signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain, and headaches.  Then, vomiting, diarrhea and rash usually follow, along with decreased function of the liver and kidneys.  At this time, some people begin to bleed both internally and externally.  The disease has a high risk of death, killing between 25 and 90 percent of those infected, with an average of about 50 percent.  This is often due to low blood pressure from fluid loss, and typically follows six to sixteen days after symptoms appear.
