The authorities in mexico City were quoting figures of 159 deaths while the WHO was saying there were only 9 deaths. Clearly a discrepancy this large pointed to some very large problem. In the end we found out that the Mexican government had no swine flu testing facilities and were sending the tests to Canada with a 5 day delay to get the results back. Clearly their numbers were guesswork and in all probability included standard flu deaths and possibly others with similar symptoms. As the WHO numbers began to rise, the Mexican numbers began to fall at a much faster rate. Currently the WHO claims that there have been 60 confirmed deaths in Mexico 99 less than originally reported.
