Stigma
S2 E14:
While Enterprise visits a planet where an Interspecies Medical Exchange conference is taking place, Dr Phlox tries to obtain research on a terminal disease from the Vulcan contingent there. However, he must not reveal that T'Pol has contracted this disease, because that knowledge would forever stigmatize her among her people.
