Oops, I should have fact-checked before hitting the “post” button. The Marburg virus was imported into Germany in an African green monkey. Laboratory workers first became ill. Altogether, 31 people became ill and 7 died. And the virus never spread beyond that initial outbreak.
Marburg spreads the same way as Ebola.
In the 1970s, especially virulent outbreaks of Lassa Fever caused a panic similar to that which now attends popular discussions of Ebola. Today though, supportive measures and antiviral drugs are effective enough that 75% or more of even those hospitalized due to severe Lassa fever infections survive. US Army researchers also have a promising vaccine candidate on the verge of human trials.
My guess is that is where we will be with Ebola in a decade or so: no major outbreaks in the developed world, and with Africa beginning to benefit from treatments and vaccines that the US and Europe have developed, just as has happened with the Lassa Fever and Marburg viruses.
