I didn't have time to write about this last week when it rolled around, but James Nachtwey's TED Wish turned out to be a series of photos highlighting a particularly resistant strain of TB, which is taking many lives globally: XDR-TB. From the site:
[I]n 2007 alone, TB killed 1.7 million people. That’s 4,660 deaths a day, or one death from TB every 20 seconds. TB is the leading killer of people with HIV: Individuals are able to live with HIV but are dying from TB. Without proper treatment, 90% of those living with HIV die within months of contracting TB.This Time magazine article also includes the above video with Nachtwey's photography.
