Late to the conversation, but I just wanted to clarify a few medical points for any future readers.
While it used to be true that HSV-1 was usually oro-labial and HSV-2 was usually uro-genital this has shifted over the last several decades (presumably as a result of changes in sexual behaviours). Either strain can infect any location, including areas other than the mouth/genitals. (For instance, a herpetic whitlow is an infection of the cuticle of the fingernail.) Some information may be coming from outdated sources.
The risk of newborns contracting HSV from kissing / touching by anybody after they are born has been well addressed.
The primary medical concern for the pregnant partner would be that a partner contracts oral or genital HSV from another partner (via oral sex, penetrative sex, kissing, cuddling or any other route) and then passes the infection to a pregnant person's genitals (by whatever means) causing a PRIMARY (first time) genital HSV outbreak during pregnancy. (In this particular case, husband contracts HSV from oral sex/kissing and then performs oral sex on pregnant wife.) THAT is, indeed, a huge deal. The fact that many people have HSV and don't know it and that barrier methods do not reliably prevent transmission means that an excess of caution is prudent when it comes to pregnancy.
Latent (inactive) HSV, like VZV (varicella zoster virus - which causes chickenpox and reactivates as shingles), "hibernates" in neural ganglia and therefore is not detectable on skin surfaces unless there is (or is shortly going to be) an outbreak. There are two types of tests for HSV. A PCR swab test is used if there is a lesion/rash on the surface of the skin or mucus membrane and confirms the presence of the HSV virus. The other test is a blood test for antibodies. It does distinguish between HSV-1 and HSV-2, but it does not help determine where the virus is hiding. And since, as mentioned above, a person can have either or both viruses in any location (and, in fact, in multiple locations) and HSV is incredibly common, the test has limited clinical utility. That being said, you can certainly request the bloodtest from your healthcare provider, as knowing a completely negative status can give you a data point for that exact moment in time. HSV does not survive long outside of the human body so a person is unlikely to contract HSV from contaminated objects (toilet seats, towels, etc - although I would still avoid sharing utensils/glasses (oral) or sex toys during an outbreak).
Antiviral medications, such as valacyclovir, are very safe and are effective in suppressing outbreaks, and thereby transmission, of HSV. We routinely use antiviral prophylaxis (preventative treatment) during the last month of pregnancy to prevent genital outbreaks at the time of delivery in women with known HSV. An active genital outbreak is a contraindication for vaginal delivery and necessitates a Cesarean delivery, ideally before rupture of membranes.
Final thought: We really, REALLY need a vaccine!
