That brings up an interesting question since the ebola virus was only known to continue to exist in a 'cyst like' state for up to 500 days.
This outbreak was only recently discovered and identified as a re-infection of the original 2014- 2016 exposure just days ago.
This information is new, and may result in re-evaluation of other previous ebola viral outbreaks,
..or even re-consideration of other viri.
This is a significant scientific anomaly !
Thanks as usual.
