Some presentations of the virus are also characterized by vascular damage, bleeding diathesis, fever, and multiple organ involvement. Clinical diagnosis of VHF has proven to be difficult based on the nonspecific symptoms.[en.wikipedia.org]

Venezuelan hemorrhagic fever (VHF) is a severe disease characterised by fever, malaise, sorethroat, followed by abdominal pain, diarrhea, a variety of hemorrhagic manifestations and convulsions.[utmb.influuent.utsystem.edu]
Principal symptoms among the patients with VHF included fever, malaise, headache, arthralgia, sorethroat, vomiting, abdominal pain, diarrhea, convulsions, and a variety of hemorrhagic manifestations.[ncbi.nlm.nih.gov]
The infection has symptom fever, has symptom headache, has symptom myalgia, has symptom sorethroat, has symptom weakness, has symptom anorexia, has symptom nausea, has symptom vomiting, has symptom convulsions, has symptom epistaxis, has symptom bleeding[malacards.org]
Key features of VHF include gradual onset of a febrile illness with sorethroat, headache, myalgia, and other non-specific symptoms. Conjunctivitis, lymphadenopathy, and facial edema may occur.[ahcmedia.com]

A description of clinical presentations of Venezuelan hemorrhagic fever includes "fever, toxicity, headache, arthralgia, diarrhoea, conjunctivitis, pharyngitis, leucopenia, thrombocytopenia, and haemorrhagic manifestations.[rense.com]
The onset is gradual with fever and malaise, tachypnea, relative bradycardia, hypotension, circulatory shock, conjeunctival injection, pharyngitis, lymphadenopathy, encephalitis, myalgia, back pain, headache and dizziness, as well as hyperesthesia of[google.com]
These data suggest that S. alstoni usually develops a persistent nonimmunizing infection with Guanarito virus, while Z. brevicauda develops an immunizing infection.[ncbi.nlm.nih.gov]
Epidemiological informations suggest that VHF has a cyclic behaviour, with epidemic periods of high incidence, every 4-5 years. During the interepidemic periods few VHF cases are reported.[utmb.influuent.utsystem.edu]
The book also includes a resource center describing places to start searches on the World Wide Web, guidelines for finding and evaluating information, suggested study projects, and strategies for encouraging communication among course participants.[books.google.com]
The results of analyses of the primary structures of the glycoproteins of the 8 strains of Guanarito virus isolated from humans suggested that these strains would be highly cross-reactive in neutralization assays.[ncbi.nlm.nih.gov]

Most patients begin to improve after 1 or 2 weeks, but the disease takes a more serious course in about a third; some patients develop a hemorrhagic diathesis; some develop severe neurological deterioration marked by delirium, coma, and convulsions; and[medical-dictionary.thefreedictionary.com]
In contrast, recent seizures or observed seizures at the time of admission were associated with a very poor outcome-16 (72.7%) of 22 died.[ahcmedia.com]
Seizures occur in some people with meningitis or encephalitis. Viruses cause a wide array of skin infections. Herpes simplex viruses (HSV) cause some of the most common skin infections.[livestrong.com]
Often, victims have seizures and lapse into a coma prior to death. Hemorrhagic diseases are difficult to treat. One reason is because of the rapid progression of the disease.[science.jrank.org]
Neurological manifestations, such as tremor of tongue and hands, diminished deep tendon reflexes, lethargy, and hyperesthesia, often occur.[medical-dictionary.thefreedictionary.com]

The New World arenavirus Junin virus (JUNV) causes Argentine HF, a severe illness with hemorrhagic and neurologicalmanifestations and a case fatality of 15 to 30%, whereas the arenaviruses Machupo virus (MACV) and Guanarito virus (GTOV) emerged as causative[dx.doi.org]
The symptoms of these central nervous system infections overlap and can include fever, headache, neckstiffness and light sensitivity. Mental status changes are common, including confusion, mood instability, extreme lack of energy and possibly coma.[livestrong.com]
Treatment is supportive, with careful attention to fluid and electrolyte balance. If untreated, the case fatality rate may reach 30% or more. With aggressive treatment, the usual prognosis is complete recovery.[medical-dictionary.thefreedictionary.com]
Treatment and prevention for the VHF virus are limited and there are currently no licensed vaccines available that can act to prevent the disease. However, once infected, Ribavirin, an anti-viral drug given intravenously, is one way to treat VHF.[en.wikipedia.org]
Thus, passive antibody therapy may prove beneficial in the treatment of human disease caused by strains of Guanarito virus that are enzootic in the region in which Venezuelan hemorrhagic fever is endemic.[ncbi.nlm.nih.gov]
In many cases, treatment for a viral illness involves relieving symptoms until the body's immune system clears the infection.[livestrong.com]
