I was excited to find the following graphs in a WHO report on global surveillance of potential epidemic infectious diseases because in the plague chapter is this awesome chart that I plan to have students grapple with (What can you conclude here? List all the possible reasons plague cases went up in Vietnam. How could you have tested those hypotheses at the time? etc etc).
But then I noticed a major goof. At least I think its a goof. And its exactly this kind of goof which causes me to doubt everything I am looking at. Argh.
Maybe this would be a great lesson for students in being critical of your information.
