unidentified viral haemorrhagic fever
ribavirin
Ribavirin may be given if a viral haemorrhagic fever is suspected until yellow fever is confirmed, either clinically or by a laboratory, as it has some efficacy in other viral haemorrhagic fevers.[13]Vasconcelos PF, Costa ZG, Travassos da Rosa ES, et al. Epidemic of jungle yellow fever in Brazil, 2000: implications of climatic alterations in disease spread. J Med Virol. 2001;65:598-604. http://www.ncbi.nlm.nih.gov/pubmed/11596099?tool=bestpractice.com
However, as ribavirin has been found to be ineffective for yellow fever in monkey studies, it is discontinued once yellow fever has been confirmed.[41]Huggins JW. Prospects for treatment of viral hemorrhagic fevers with ribavirin, a broad-spectrum antiviral drug. Rev Infect Dis. 1989;11(suppl 4):S750-S761. http://www.ncbi.nlm.nih.gov/pubmed/2546248?tool=bestpractice.com
Primary options
ribavirin: 33 mg/kg intravenously as a loading dose, followed by 16 mg/kg every 6 hours for 4 days, then 8 mg/kg every 8 hours for 6 days
supportive therapy
Treatment recommended for ALL patients in selected patient group
Patients should be hospitalised for supportive care and observation when possible.
This involves rest, maintaining nutrition and preventing hypoglycaemia, nasogastric suction to prevent gastric distension and aspiration, H2 antagonists (to prevent gastric bleeding), treating hypotension with fluid replacement and vasoactive drugs, giving oxygen, correcting acidosis, treating bleeding complications with fresh frozen plasma, haemodialysis for renal failure, and treating secondary infection with antibiotics.[2]Monath TP. Yellow fever: an update. Lancet Infect Dis. 2001;1:11-20. http://www.ncbi.nlm.nih.gov/pubmed/11871403?tool=bestpractice.com Analgesics/antipyretics are recommended for pain and fever; however, non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin, should be avoided due to the increased risk of bleeding in these patients.
Critically ill patients (i.e., those with multi-organ failure, severe haemorrhagic complications, and/or refractory hypotension) require intensive care monitoring.
The above recommendations are based on clinical experience, but have not been evaluated in clinical studies.[2]Monath TP. Yellow fever: an update. Lancet Infect Dis. 2001;1:11-20. http://www.ncbi.nlm.nih.gov/pubmed/11871403?tool=bestpractice.com
Patients should be isolated/protected from further mosquito exposure (e.g., staying indoors) for up to 5 days following onset of fever to break the transmission cycle.
