What is the likelihood of you catching Herpes Simplex Virus 1 through lip kissing or French kissing in the absence of the visibility of cold sores?
It is a low probability but the possibility does exist.
There is a misconception about oral herpes spreading when you make contact with the saliva. It is actually spread by skin contact where the herpes virus is existent.
However, it is not impossible that you can get Herpes Simplex Virus 1 from kissing.
HSV-1 Spreads by Skin-to-Skin Contact
Herpes Simplex Virus 1 spreads with direct contact of the skin unlike the influenza virus that can even spread through the air. In the case of HSV-1, it spreads directly from the infected site to the site of contact. For example, if you suffer with cold sores and you kiss someone, you can transmit the virus to the person’s mouth. The virus will spread when cold sores are visible. Herpes can spread by kissing from the time these symptoms are noticeable until the time the affected area gets completely healed and the skin becomes normal again.
HSV-1 can Spread Even There is not any Symptom
The cold sores could be present on the inside of lips and it is not necessary that these sores should be visible for the virus to be present in that affected area. There is a possibility that Herpes Simplex Virus 1 could spread even when the sores or lesions cannot be seen. There are few theories that people who are infected with the virus could shed or transmit it without the presence of any symptoms.
The chances of contracting herpes, however, are low when two people kiss as it is not necessary that one of the infected persons should transmit the virus through a kiss. With French kissing, the odds are high when compared with other forms of kissing which are less intimate. The odds are also strong if an infected person has acquired the virus recently in comparison with a person who has a chronic condition.
