If you kiss someone with a cold sore will get it?

It is possible to get a cold sore by kissing someone who has one. Cold sores are caused by the herpes simplex virus, which is transmitted through direct contact with infected saliva or skin. When someone with a cold sore kisses someone else, the virus can be transferred to the other person's mouth or skin, where it can cause an infection.

Not everyone who kisses someone with a cold sore will get it, but the risk is higher if the person with the cold sore is actively shedding the virus. This means that the virus is present in their saliva or on their skin and can be easily transmitted to others.

The risk of getting a cold sore is also higher if you have a weakened immune system. This can be due to a variety of factors, such as stress, illness, or medication.

If you have a cold sore, it is important to avoid kissing others to prevent spreading the virus. You should also wash your hands frequently and avoid touching your eyes or nose.
