The most deadly outbreak of Marburg occurred in Angola in 2004-05 that killed 227 people. The virus causes a hemorrhagic fever. There are no vaccines or treatments for the virus, but symptoms can be relieved through palliative care, which increases the chance of survival. It is transmitted by fruit bats that come into contact with humans through the consumption of bush meat. Humans transmit the disease by body fluids or contaminated objects. It was first discovered in 1967 in Marburg, Germany. Tanzania is battling its first outbreak just a month after Equatorial Guinea confirmed its first case.
