Herpes Simplex (Cold Sores), Herpes Zoster (Shingles)

Herpes Simplex (Cold Sores)
Herpes simplex is one of the most common infections of man. The virus most often affects the lips, however other parts of the body may also be affected. The lesions usually continue to recur in the same site. Herpes simplex virus infections occur in two phases. Often the primary phase is undetected and is most common in pre-school children. Symptoms include swollen gums which bleed easily and fluid filled blisters on the gums, tongue and pharynx. Blisters may also appear on lips and surrounding skin. These blisters rupture to form white plaques and ulcers.

Recurrent herpes simplex lesions usually begin with tingling or itching followed by the appearance of small fluid filled blisters on reddened skin. These blisters are usually smaller than those of the primary infection andare clustered closer together. The blisters last only a few days before they become crusted. The lesions usually heal in about a week and do not usually leave scarring. Recurrent herpes simplex lesions may be due to exposure to sunlight.

Herpes Zoster (Shingles)
Herpes zoster is believed to be a re-infection with the Varicella zoster virus that causes chicken pox. Evidence indicates that herpes zoster is caused by a virus similar to chicken pox. It is an acute, systemic infection which results in skin eruptions of groups of blisters on a red base with pain and itching. The blisters are typically situated on the chest wall on one side, along the line of the intercostal nerves or on the face. The spinal ganglion is the principal seat of infection and the number of ganglia ninvolved partly determines the extent of the skin eruptions. Medical attention is required for this condition. Persistence of pain is common,  particularly with advancing age and if the facial nerve becomes involved.

In children, the eruption is usually painless but may be very itchy, with little systemic involvement. In adults, pain is often greater than the itching. The condition usually begins with pain which is followed after 3-4 days by the formation of vesicles. These vesicles are usually situated along a nerve segment. They gradually become pustular then rupture forming crusts which fall off after 2-3 weeks. Scarring will usually occur. Herpes zoster can affect any nerve segment. The lymph nodes in the area of the nlesions are usually enlarged.

Consult a medical practitioner. Anti-viral medication may be indicated. Topical anti-inflammatory and anti-pruritic treatments will help the patient feel more comfortable. An antibiotic may be necessary if crusted lesions become infected.

To prevent recurrent lesions of herpes simplex, an SPF 30+ should be applied to the lips and surrounding skin daily.

The patient should be advised to avoid using soap on the affected area as it may further irritate the skin.
