A 17-year-old female asked:

Stop prednisone: Prednisone suppresses your immune system which can reactive HSV-1 (the cold sore virus) which normally remains inactive in your skin for life. I would recommend stopping Prednisone and switching to a topical steroid to treat the outbreak. There are topical and systemic therapies that can be given to suppress future cold sore outbreaks and I would discuss these with your doctor.

Cold sore flare up: Steroids are a double edged sword. If your rash was really that bad probably you needed the steroids, but now the immunosuppressive effect has allowed a different problem to arise. The cold sore virus, HSV-1, is always waiting to come out when the body is weak--through stress, other sickness (fever blisters) or medications. Hope u can wrap up the steroids soon.

Maybe: There is some evidence that herpes simplex viruses inside brain and nerve cells can create the type of damage seen with Alzheimer's patients, if the patients have particular genes that make them vulnerable to the effects of the herpes viruses. If more research shows this to be true, then treatment or prevention of herpes simplex viruses can become a way to prevent Alzheimer's dementia.

What type of herpes simplex virus causes cold sores?

Dr. Robert Kwok
Pediatrics 33 years experience
Type 1 more common: Cold sores on or near the lips are due to recurrence of herpes type 1 or 2. Herpes viruses, after the initial infection, live in a person's nerves and travel down the nerves to the surface to form blisters that break open, spreading more virus. Type 1 is more common on the lips, and type 2 more common on the genitals. With people engaging in oral sex, either type can be in one or both locations.

Viral infection: Herpes encephalitis is a viral infection ususally due to herpes simplex type 1. The infection affects the temporal and frontal lobes of the brain, areas important in the formation of new memories. The infection is progressive if not treated, leading to death. Intravenous antiviral medication is very effective especially when given early in the course of the infection. Recovery can be good
