Can eczema herpeticum be prevented?

Eczema herpeticum happens when herpes simplex infects skin affected by eczema or another damaged skin barrier. It can cause clusters of painful, similar-looking blisters or shallow round sores, sometimes with fever or marked tiredness. The infection can spread quickly and may affect the eyes. Prevention focuses on keeping eczema inflammation and cracking under control, protecting open areas, and limiting exposure to herpes sores. A person with a cold sore should avoid kissing, close skin contact, and sharing towels, lip products, or utensils until the sore has healed.

Use the eczema treatment plan consistently, moisturise as advised, and keep fingernails short to reduce damage from scratching. Wash hands after touching a cold sore and avoid touching your eyes or eczema patches. Do not apply another person’s antiviral cream to broken skin. Tell your dermatologist if you have repeated exposure to cold sores or a history of eczema herpeticum; an individual plan may include rapid access to antiviral treatment. Check with a clinician before treating a new blistering eruption as ordinary eczema.

Seek same-day medical care for a sudden crop of painful blisters or punched-out sores on eczematous skin, especially with fever, weakness, swollen glands, or rapidly spreading areas. Get urgent eye assessment for eye pain, light sensitivity, redness, or blurred vision. Early antiviral treatment matters, so do not wait for the rash to settle with moisturiser or usual eczema cream.
