To pass hepatitis on to your lover is a crime
In Italy, to have sex with your lover, without any precautions and not mentioning the fact that you suffer from chronic hepatitis, is crime of bodily injury. For this reason, the Supreme Court confirmed the conviction of a man, for having hidden his real state of health during the whole extramarital sexual relation and having infected his illicit partner.
Not considering valid the excuses of the accused. Including the fact that his wife, however, was not affected by this disease and therefore he could not have passed it on to the paramour.
