Prostitution is pregnant with disease, a disease infecting not only the guilty, but contaminating the innocent wife and child in the home with sickening certainty almost inconceivable; a disease to be feared with as great a horror as a leprous plague; a disease scattering misery broadcast, and leaving in its wake sterility, insanity, paralysis, the blinded eyes of little babies, the twisted limbs of deformed children, degradation, physical rot and mental decay.
