When is it safe to kiss after a cold sore?

In most circumstances, a cold sore will no longer be infectious at the crusting or healing stage.

However, occasionally, this part of the cold sore cycle may not always be clearly defined and hence, viruses could still be multiplying and active.

So, to be 100% certain that one does not pass on the virus with a kiss, wait until the cold sore has resolved completely.
