Solid numbers can be hard to come by in this type of situation. There have been forty reported cases in the U.S.; the first twenty of these have already recovered. In Mexico, one report mentions 1,000 cases and eighty deaths; another, twenty-six cases and seven deaths. While the same virus appears to be responsible for cases in both countries, there's no explanation for these different outcomes.
The current virus is similar to [the 1918] virus in that both are H1N1 viruses.
