For what it is worth, the folks on the ground need map data, which does not exist.
You can help trace satellite imagery for the responders on the ground.
I work with MSF daily and they direct where the mapping needs to be completed, you trace sat imagery, lives get saved.
There is no way, short of travelling to DRC and (a country to be named in the coming days), to help folks on the ground suffering and combating this outbreak more directly than mapping. You trace, they use the map data (as imperfect as it will be) literally the next day.
