Pathophysiology: Viral hemorrhagic fever (VHFs) is a general term to severe group of illness caused by RNA viruses from several viral families. It is a severe multisystem syndrome caused by infectious viruses which lead to a potentially lethal disease syndrome characterized by fever, malaise, vomiting, mucosal and gastrointestinal (GI) bleeding.VHF is caused by viruses of four families: arenaviruses, filoviruses, bunyaviruses, and flaviviruses.
Disease Statistics: According to a study in published in 2012, Dengue is not endemic in Australia but outbreaks occur in north Queensland where A. aegypti mosquitoes are established. A previous astudy of 2002 reported 0 new cases of viral haemorrhagic fever per 100,000 populations.
Treatment: Patients usually receive supportive therapy but as such there are no other treatment or established cure for VHFs. Ribavirin, an anti-viral drug, have been effective in treating some individuals with Lassa fever or HFRS. Treatment with convalescent-phase plasma has been used with success in some patients with Argentine hemorrhagic fever.
