Much of the world isn't actually under control of a government. Here in the developed world, we've basically bought into the nation-state system, with a strong central government controlling a defined territory with border checkpoints. But many parts of central Asia, the Middle East, Africa, and rural areas in other continents aren't like this. The dominant social organization is by tribe, clan, cartel, gang, or warlord; borders are porous or nonexistent; and the government has no authority, not even a monopoly on physical force.

The virus doesn't care whether you believe in governments, and it's just now hitting these regions - Pakistan, Africa, North Korea, etc.
