Sa'id bin al-Musayyib (may Allah have mercy on him) said that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) ruled that if a woman has one of these diseases and the man does not know, but has intercourse with her, then in return for that she is owed her dowry, and the husband may recover an amount equal to the dowry as a penalty from the woman's guardian.
