The estimated evolutionary rate of the whole Marburg virus genome is 3.3 × 10− 4 substitutions/site/year.
Bayesian analysis suggests that the MARV strain most probably originated in Uganda about 177.9 years ago.
It also suggests that the RAVV strain originated in an area between Uganda and Kenya about 33.8 years ago.
Our data indicates Uganda as the cradle of the Marburg virus in Africa.
