If 70-80% of people have had coldsores, how come genital hsv 1 is not more common?

Not so easy to pass. Nowhere near 70-80% of all people (in North America) have had cold sores. By age 40, around half of all adults have positive blood tests for HSV1. Probably about 20-25% of them have had overt oral herpes outbreaks, i.e cold sores. Why not more genital HSV1? Because in oral sex, when the oral partner has HSV1, transmission occurs infrequently -- as a guess, about once for every 1,000 exposures.

HSV1. Early signs of a type 1 genital herpes infection usually appear within two to three weeks of exposure to a partner who has the virus. The early symptoms of an oncoming herpes outbreak include itchiness, tingling or pain in the genital or anal area. Some people may experience some swelling and unusual redness in the affected area, as well. For women, the symptoms may develop in the vaginal area. Read more...

No. If a person has antibodies to HSV1 (has immunity), she should not get new HSV1 infections in places that she did not get HSV1 sores in the past. New herpes lesions on the genitals would be presumed HSV2 (if the HSV2 antibodies turned positive on the blood tests after the new genital herpes sores). Life can surprise you sometimes. Maybe HSV1 was in the genitals in the past but wasn't noticeable. Read more...
