If the EBV+/EBV- characteristic can be considered ordinal, then you can do a test of the dominance statistic to see if one distribution is ordinally higher than the other... but, I'm pretty sure, no matter what statistical hammer you apply to this data you are not going to find a significant difference. It is probably not worth the effort to dig up how to do a dominance test (not included in any stats packages I've seen).
