"Averages don’t tell you very much. You could have a student transmitting to 15 others, while the average in Queens is 0.1. It’s like putting Bill Gates down in Ethiopia and saying the country has a pretty high average income."
DR. DIRK BROCKMANN, leader of the epidemic-modeling team at Northwestern University.
NB: 10 Days off of Purgatory for anyone who can tell me what the heck an 'epidemic-modeling team' might be.
