It is the pathological fear of catching a sexually transmitted disease (STD), and by extension prostitutes who can transmit them. The origin has a curiosity, and that is that these diseases are called 'venereal' in allusion to the Latin goddess of love and sex Venus or Venera; but it turns out that phobias are baptized with names taken from the Greek, so their mythological equivalent Aphrodite had to be used by one of their names, which is Kypris, taken from the Greek name 922; 965; 960; 961; 959; 962; ( Kypros ) for the island of Cyprus where the goddess was born according to some traditions, to add the suffix -phobia.
