This is unrelated to the general thrust of this thread, but I'd like to point out that the arbitrary nature of Africa's "borders" make it impossible to contain threats like Ebola. Let's consider Nigeria.

1. https://t.co/EDpqZaUSYw This town in SW Nigeria with direct links to Cote D'Ivoire

2. It is possible to go by speed boat direct from Uyo in Akwa Ibom state to Malabo in equatorial Guinea

3. Nigeria and Sudan have long historical links, impossible to polise movement between both nations.

Implications for national security and also spread of infectious diseases.
