Is marrying a girl infected with Hepatitis C, given the availability of preventive measures, considered throwing oneself into destruction and therefore forbidden?

One must be cautious of what is harmful, based on the hadith: "There should be neither harming nor reciprocating harm," and "A sick person should not be brought to a healthy one." If the suitor is aware of the woman's illness, is content with it, and believes it is possible to prevent harm, then it appears permissible for the marriage to proceed, and he should cooperate with her in seeking treatment.
