How long can the herpes virus live outside a host?
In nine adults with virus-positive herpes labialis, herpesvirus was detected in the anterior oral pool of seven (78%) and on the hands of six (67%).

Results are available within 16 hours to 7 days of receipt of the specimen, depending on the culture method used.
How long does it take for HSV-2 to show up in blood?
