From a doctor's diary. Can you get it twice, doctor?

From a doctor's diary This is based on a doctor's experience of cases of V.D. It has been carefully edited so that the people concerned shall not be recognised. "'...Can you get it twice, doctor?' Yes, I'm afraid you can. Venereal diseases are not like the ordinary infectious diseases—mumps, and whooping cough, and measles and so on. If you've had these once, you're usually safe. But that's not the case with V.D. You can catch V.D. just as often as you take the risk. Just recently I saw a man who first came to see me ten years ago.
