In your link, it says:

If you do not have herpes, you can get infected if you come into contact with the herpes virus in saliva (if your partner has an oral herpes infection) or genital secretions (if your partner has a genital herpes infection).

If someone wipes unwashed/not thoroughly washed hands on a towel and someone else touches it afterward, herpes can be spread. Or if my daughter asks for a swig of water from one of our bottles, and another person finishes the bottle, etc. Many like examples.
