Hello,
Although molluscum contagiosum is a viral infection but reinfection can occur. It can also occur on the same areas where the lesions were present. There is no hard and fast rule for that.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Another question, has anyone on the forum, seen/herd of Molluscum lesions around the mouth?
