Distance from one set of xy coordinatesto another set of xy coordinates

Just looking for some brief input into an issue I'm having. I have two shapefiles with xy coordinates for each individual; one has data on disease (0,1) in species 1 and the other has data on disease (0,2) in species 2. Basically, background research suggests that infected individuals in species 1 increase the risk for infection in species 2 individuals. Therefore, I want to calculate if positives in species 2 are more likely to be located near positives in species 1.

I'm fairly familiar with statistics, but I've just started delving into spatial statistics. I think an appropriate analysis might be a bivariate K-function, but I'm not sure how that would be accomplished with ArcGIS and there also might be other more appropriate analyses that I haven't considered.

Thanks in advance.
