There are certain diseases that people could transmit to their spouse if they had a past. That is the reality. Many of these diseases could not even come up right away, it could take many years. A girl who is marrying someone wouldn’t even imagine that she is being put at risk. Now is that fair?
Now in Mexico, before you get married the govt makes you take a blood test to make sure you are not HIV positive. That is for only one of the many infections that could be transmited. Suppose someone comes out positive? Suppose his wife comes up with something after being married for a few years? What should they do, blame it on a blood transfusion? I really don’t want to imagine what that shalom bayis will be like then.
