I wouldn’t consider Lyme an “issue”, so much as something to be aware of and filed away accordingly. It’s a simple reality of living in the NE, but it is still overall very uncommon, particularly on the list of “stuff to worry about”. People who enjoy the outdoors should do tick checks, but no further concern is necessary. Other regions have their parasite-, environmental- and food-borne illnesses too, like various mosquito-borne encephalitis viruses, histoplasmosis, cysticercosis, etc.
And as far as infectious diseases spread on any campus (BS, college or other), there are far more common pathogens to be aware of.
