To help please describe the exact circumstances of your daughter's herpes diagnosis.
If she had a bad breakout of lesions that prompted her to see a doctor who swabbed the lesions to return a positive for HSV, then there is almost no question the sexual partner in the preceding 2-10 days is the source.
Other diagnoses would require some more interpretation. Whether she has HSV1 or HSV2 would also be quite relevant, particularly if she has had oral cold sores from her youth for example.
Hi, no there is not but test results and the most recent sexual partner may shed light on this.
