The number of DR Congo Ebola cases has been constantly doubling every three months. It can reasonably be expected to become the biggest ever outbreak of Ebola overtaking the West Africa outbreak by the end of March 2020. Presumably it will be repeatedly entering the various world regions by that time - USA, Europe, Far East, South America, Middle East, Russia, etc..It cannot be stopped at source by medics and governments this time because of warzones so it will just keep incubating there, perpetuating the spread into other regions. Pressure will mount to close more and more airports.
