We seem to be on a roll here, with open-source publishing and web 2.0 technologies being co-opted by “authoritative” sources. This latest case connects Healthmap.org, with the prestigious New England Journal of Medicine. Working together, they have developed an interactive map charting H1N1 cases and deaths as reported by the media. Although they have stopped tracking reports from “official” sources such as the CDC and WHO, hovering over any incident shows the media link, even when the report is not in English, so you can check the authority of the report yourself.
One of the most interesting features is the ability to track the progression of the virus, on a date range and map level that you specify. There is also a listing of the most current H1N1 news.
