DeathStrobe, it isn't that "elves do it better", but the fact that for an epidemic to spread, one must first have exposure to it. In this case, the places best capable of staving off CFD would be the Tirs, and places like Africa. This isn't because of things they do better, but because of what they LACK, that other countries have. For the same reason, which country do you think would be most affected by a crash of the global data networks today, the USA or Somalia? Clearly Somalia would be better off, because they are far less reliant on data networks, what few actually are up and running in the country.
Places that are isolationist, deliberately low-augmentation, or third world hellholes with limited technical resources are going to be the safest from a disease like CFD. Yes, this is the opposite of what most people think of when doing disease tracking, but CFD is an atypical affliction, in that it is more likely to be prevalent in the most affluent and most advanced areas with the best medical care, while a disease like VITAS would be more easily fought there.
These are the advantages that Tir Tairngir has, which the UCAS does not when regarding CFD:
* Secure borders that they can (and do) patrol regularly, most of which are also inhabited by very lethal paracritters or stranger things.
* Secret police that can (and do) monitor people for changes in behavior (rooting out terror cells).
* Anti-augmentation bias in a good segment of the population (both due to magic, and elven snobbery about not 'needing' augmentations).
* Lack of megacorporate influence allowing for greater national controls.
* A less mobile population, resulting in any infection zones to be more easily contained.
* Willingness to use extreme prejudice to eliminate threats, and keep said actions from being commonly known.
* A more stratified society, with fewer people meeting those outside their 'level'.
Sure, those don't eliminate the possibility of a CFD infection, particularly in a sprawl close to the border like Cara'Sir, but together, they present a formidable defense for the majority of the country, especially those in power. It isn't that they fight it better (other than being willing to kill the infected and utterly destroy the remains with extreme prejudice), but that they've set themselves up so that they are less likely to get large numbers of infected in the first place, which makes containment easier. To use another example of real world diseases, what is easier to contain, one Ebola patient, or twenty? Because of how they're set up, Tir Tairngir is more likely to catch 'anomalies' when it is at the level of a hundred or so infected, rather than the thousand or so it might take the UCAS or megacorps to realize that there is a problem.
