I'd first suggest getting some structure to your data. It looks like you have broken down what you have so far by country, is every country going to have the same data?
i.e. for Algeria you have the definition of Yellow Fever, and for american samoa you have country stats.
is there a comom theme between countries? Tell us some more and Im sure we can help.
also, can you give us a link to this 'who' website?
