The most contagious person is the one who is currently going through one of the visible stages of the oral herpes. The most dangerous stages are the points when small blisters form, later bursting in a painful way and releasing their content full of new viruses into its surroundings.
In this stage, it is especially important to adhere to preventative measures – if you do have oral herpes as well as if you want to prevent the infection.
People who repeatedly suffer from herpes of the lips usually know best what the trigger for them is. For someone it is freezing weather, for others the sun at the seaside, for yet others shock or stress – each person is unique. First of all, try to find out what is your trigger, thus you will be more successful in avoiding it and lowering the risk that herpes will appear again.
It is not difficult, all you need is strong will and discipline.
