The inbound tourism idea is something I didn't think about. Transmission may depend a lot of people transporting it from one geographical region to another, and that might be less common in the developing world simply due to worse transport networks and people living and working more locally in general. E.g., more people from the UK go to Spain on holiday than people from Gambia.
