All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
It is permissible for someone who was infected with a transmittable disease to get married, but he must inform the person he wants to marry about it. Please refer to Fatwa 156813.

Allaah Knows best.
