Did you also have a blood test done at the time? If your last sexual exposure was more than 10 years ago, a blood test would be a much more reliable test than a swab, particularly if the sore had already scabbed over.
If the swab results are negative, I'd still recommend a type-specific IgG blood test to completely rule out herpes. Swabs are frequently falsely negative, particularly with recurrences vs initial infection, and particularly if the swab isnt' taken within the first couple of days of the sore forming.
Hi and yes it would. Its getting fairly common and only recently discovered that it could be contacted that way.
