It is not possible to tell exactly what these spots are without actually seeing them, so the best thing to do is to speak with her primary care physician
. Certainly herpes simplex virus infection is on the list of possibilities, but there are other possibilities as well. There are two types of herpes simplex viruses, HSV-1 and HSV-2. 90% of the genital infections are caused by HSV-2 whereas 10% of them are caused by HSV-1. The opposite is true for the oral cold sores that are caused by HSV. When someone such as your daughter comes in having had a blood test showing exposure to HSV-1, gentle herpes is certainly not suspected based on that test alone. Spending time in the hot tub can cause an infection with bacteria that invade hair follicles. In this case, these bumps could represent folliculitis exacerbated by the bacteria she obtained in the hot tub. This kind of infection might go away on its own. The only way to tell for sure what has happened here is to allow time pass and see if she has another outbreak. If she stays off of the herpes medications, chances are that eventually she'll have another outbreak if she does have herpes. At that time you can schedule an appointment with her primary care physician for an exam to get a better look at these lesions and further blood testing. Good luck.
