The herpes simplex virus (HSV-1) is a common viral infection that results in cold sores. They can be itchy and unpleasant and are distinguished by a cluster of small, fluid-filled blisters that are generally located on or near the lips. Kissing or other close contact with the saliva of an infected person can easily spread cold sores, which are highly contagious.

There is a possibility that you could catch the virus from someone who has a cold sore and get one of your own if you kiss them. This could occur at any time, depending on a number of variables.

It’s crucial to first comprehend how the herpes simplex virus functions. Once the virus enters the body, it remains there for life, residing in the nerve cells of the skin. Long amounts of time can pass before the virus goes into dormancy, but when stress, illness, or sun exposure awakens it, cold sores can start to appear.

If you kiss someone who has a cold sore that is still active, their saliva may contain the virus, which you could then contract. It’s important to note that a person with a cold sore can be contagious even if they do not have visible blisters or sores.

The timing of when you might develop a cold sore after kissing someone with a cold sore can vary. Some individuals might have symptoms a few days after exposure, while others might not experience symptoms for a few weeks. The average time for symptoms to appear is around 2-12 days.

It’s also worth noting that not everyone who is exposed to the herpes simplex virus will develop a cold sore. Some people may carry the virus without ever showing any signs of illness, while others might only infrequently show signs.

There are precautions you may do to lessen your chance of catching the herpes simplex virus through kissing. Avoid kissing someone with an active cold sore, and avoid sharing personal items such as towels, razors, or utensils with someone who has a cold sore.

If you do develop a cold sore after kissing someone with one, there are a number of over-the-counter treatments available that can help to manage symptoms and speed up the healing process. These include topical creams, ointments, and antiviral medications.


If you kiss someone with a cold sore, there is a risk that you could contract the herpes simplex virus and develop your own cold sore. The timing of when this might happen can vary, but symptoms typically appear within a few days to a few weeks of exposure. Taking steps to reduce your risk of exposure, such as avoiding kissing someone with an active cold sore, can help to minimize your risk.
