Short answer
Genital herpes comes in two viral flavors, HSV-1 (rising, oral-sex-driven, generally fewer recurrences) and HSV-2 (classic genital pattern, more recurrent), distinguished by typed swabs and managed under the same precautions, with type facts shaping expectations rather than changing the rules.

HSV-1 historically caused oral cold sores, but now drives a large share of first genital episodes as oral sex transmits it to partners without prior oral exposure.
HSV-2 remains predominantly genital with established recurrence patterns.
Co-infection with both types occurs.
None of this changes precautions. It explains why “but I’ve only ever had cold sores” no longer reassures in genital contexts.
The crossover dynamic is detailed in Can You Get an STI from Oral Sex?.
Clinical differences that set expectations
First episodes run comparably severe either type.
Recurrence differs substantially: HSV-2 recurs more often; genital HSV-1 frequently quiets after the initial years.
Shedding and transmission precautions stay identical regardless of type. Expectations differ, behavior doesn’t.
Your clinician uses the type pattern when planning long-term care; patients use it to calibrate what “normal for me” looks like.
Testing for type, and its limits
Fresh-sore NAAT with type differentiation guides prognosis discussions.
Type-specific blood tests supplement only in defined scenarios (such as discordant couples or pregnancy contexts) with confirmation of surprising results. They cannot locate infection or date it.
How each test performs is compared in Genital Herpes Testing: Swab vs Blood Test.
Living with either type
Outbreak abstinence, condoms between episodes, partner disclosure with type facts, and clinician-guided suppressive options for frequent recurrences. Uniform across types.
Pregnancy with either type gets obstetric planning; eye-area lesions get urgent care.
Type knowledge refines the conversation; it never relaxes the precautions.
When to seek care
For first outbreaks (typed swabs), frequent recurrences (suppression candidacy by type pattern), pregnancy with either type, and partner evaluations.
