Is it true that L-Lysine is also affective for adults to take on a daily basis? Oddly enough - our cat has respiratory Herpes (different strain of virus) and I have been giving her Lysine. Her outbreak affects her eye - so, it greatly reduces the tearing in her eye. When we got her as a kitten we thought she had an infection until the vet told us she had Herpes.
With regards to my original question regarding bike riding - So far, no issues riding my bike with an outbreak!.
