Think about making overlap into "discrete groups" so that raccoons within a group only encounter the eggs/worms of other raccoons in that group. This will again be based on current/past prevalence in that zone. Making an contamination matrix through time where each entry in the prevalence for that zone at that time.
Summing columns and decay across rows to estimate human risk. Egg encounter and rodent worm values are a decay function running across the columns.
