It was my impression that HPV was treatable if caught early, which it presumably would be with a rape.
It’s undetectable until it has already infected the tissues. The only effective treatments are topical used against visible lesions (condylomas) which occur weeks to months after infection. Even destroying visible lesions doesn’t eradicate the infection. It can still cause malignant changes or more lesions.
Assuming the rape victim reports the rape and seeks medical treatment. That’s not always the case for many reasons.
