It's an odd framing. Out of R_t total raccoons, R_e bite or scratch (potentially "expose") humans. R_e / 10 of those were carrying rabies. So it could be that raccoons almost never bite/scratch humans, such that the behavioral effects of rabies are a significant motivator. It also could be that raccoons bite/scratch humans all of the time, and a ton of those raccoons have rabies. The latter is scary, but the former is likely the truth.

I wonder if increased interactions between humans and raccoons will lead to a reduction in that 10% figure (more reasons to bite humans).
