HSV-1 vs HSV-2 — Glossary Definition

HSV-1 and HSV-2 are two types of herpes simplex virus. HSV-1 is commonly associated with cold sores, while HSV-2 is commonly associated with genital herpes, but either type can appear in either location.

Prior diagnosis required. Bidwell treats adults ages 18-64 who have already been diagnosed with oral or genital herpes by a healthcare provider. Bidwell does not diagnose new herpes infections online, does not require photo upload, and does not guarantee treatment.

Why does the distinction matter?

The virus type, body location, recurrence pattern, and patient goals all affect counseling. Treatment medications overlap, but the emotional and practical concerns can be different.

Does Bidwell need to know my type?

Bidwell asks whether you have oral or genital herpes and whether you have a prior diagnosis. If you know HSV-1 or HSV-2 from testing, include it in your notes. If you are not diagnosed, seek testing first.

Can HSV-1 cause genital herpes?

Yes. HSV-1 can cause genital herpes, and HSV-2 can involve areas outside the genitals. That is why location and prior diagnosis are more useful for routing than assumptions.
