More than 50% of people have been infected with the HSV-1 virus, usually from well-meaning kisses from relatives or romantic partners. A parent who has a cold sore often spreads the infection to his or her child this way. The disease stays dormant in all but the unlucky few who end up getting cold sores. Genetics may play a part – new studies are tracking three genes that could relate to how HSV-1 reactivates itself, causing outbreaks.
