I asked myself the other day, how many people really watch the these images? I used Wikipedia article traffic statistics for October to check the examples that likely were the most viewed, and found out that the Häggström series are viewed by at least one million people each month:
 * AIDS: 330.000
 * Tuberculosis: 270.000
 * Cancer: 220.000
 * Black Death: 190.000
