The mean incubation time is 7 days
with initial symptoms of a flu-like illness with fever, malaise, headache, and fatigue often accompanied by swelling of lymph nodes.
Shortly after a rash can appear with lesions before scabbing. The lesions are the infectious component and usually occur at the site of contact eg throat/mouth for receptive oral sex. Most persons have fewer than 10 lesions and almost 10% present with only a single genital lesion. Hospitalisation is uncommon and the major reason for admission is usually for pain control, typically for anorectal or oral pain. Complications can occur if there is a secondary infection of the lesion. The symptoms usually resolve by themselves within a few weeks, but you are considered infectious while you have symptoms.
