Can viral hemorrhagic fevers be cured?

By yourself...: In many cases, we don't have medication to kill the viruses that can cause hemorrhagic fevers. Anecdotally, people have used iv-ig, but in general, your immune system has to do the brunt of the work. As physicians, we can pretty much help with supportive management only.

VHF's: For the most part, medical providers can give suportive treatment but it is a battle between the body and the virus. VHF's - Argentine Hemorrhagic Fever, Dengue, Lymphocytic choriomeningitis (LCM) Lassa fever, Tick borne encephalitis, hantavirus pulmonary syndrome, Rift Valley Fever, Ebola)

Naturally: There is no specific treatment for these viruses. We can only provide supportive care and if the person survives the illness the immune system will eradicate the virus.
