Herpes simplex is a common virus that typically causes localized sores on the lips or genitals. While many people experience mild symptoms, the virus can behave more aggressively in those with certain underlying health conditions. For individuals with existing skin barrier issues or a less effective immune response, the virus can spread more extensively and lead to serious complications.

The severity of herpes in individuals with eczema
The herpes simplex virus can cause a severe and potentially dangerous skin infection known as eczema herpeticum in people with atopic dermatitis. When the skin barrier is already damaged by eczema, it lacks the structural integrity to block the virus from spreading across the surface of the body. This can lead to a widespread outbreak where clusters of itchy, painful blisters appear on areas of the skin previously affected by eczema. The NHS warns that eczema herpeticum is a serious condition that requires prompt medical treatment to prevent it from spreading further. Unlike a standard cold sore, this infection can cover large areas of the face and neck, causing high temperatures and general illness.
Herpes simplex in immunocompromised individuals
Individuals with a weakened immune system are more likely to experience frequent, large, and persistent herpes outbreaks that take much longer to heal. The immune system is responsible for keeping the virus in a dormant state within the nerve cells, but when this defence is compromised, the virus can reactivate more easily. This can result in sores that are deeper and more prone to forming large ulcers rather than small, self limiting blisters. NICE clinical knowledge summaries state that people who are immunocompromised may require more intensive management to control the replication of the herpes simplex virus. In some cases, the virus may even spread to internal organs or the central nervous system, making it a significant health concern for those with suppressed immunity.
The risk of secondary bacterial infections
A major concern for vulnerable groups is the increased risk of a secondary bacterial infection occurring on top of the viral herpes sores. When the skin is broken by viral blisters, it provides a direct entry point for bacteria such as Staphylococcus aureus. For people with eczema or weak immunity, these bacterial infections can spread rapidly, leading to conditions like cellulitis or impetigo. Managing the initial viral outbreak quickly is essential to maintain the integrity of the skin and prevent these complications from developing. Keeping the skin clean and using appropriate barrier creams as advised by a professional can help reduce this risk during a flare.
Identifying the early signs of complications
Recognising the transition from a standard herpes outbreak to a more severe complication is vital for ensuring timely care. In eczema herpeticum, the blisters often look like small, punched out circles that are all at the same stage of development. If you have eczema and notice a sudden, painful rash that is different from your usual flare, it may indicate a viral infection. For those with weaker immunity, any sore that does not show signs of healing after two weeks or that continues to expand in size should be considered a red flag. Monitoring for systemic signs such as chills, extreme fatigue, or a persistent high temperature is also necessary when managing herpes in high risk categories.
Prevention and skin barrier management
Protecting the skin barrier is a fundamental strategy for reducing the severity of herpes outbreaks in those with underlying conditions. For people with eczema, maintaining a consistent routine with emollients helps to seal the microscopic gaps in the skin that the virus uses as entry points. Avoiding contact with anyone who has an active cold sore is particularly important for those with weakened immune systems or active skin disease. If an outbreak does occur, keeping the area covered with a clean dressing can prevent the virus from spreading to other parts of the body through scratching or accidental touching. Consistent hand hygiene remains the most effective way to break the cycle of transmission within a household.
Conclusion
Herpes simplex can be significantly more severe for individuals with eczema or a weakened immune system due to the loss of natural barriers and defences. Conditions like eczema herpeticum require careful monitoring and professional management to prevent serious health outcomes. By maintaining skin integrity and seeking early advice, the risks associated with these infections can be better managed. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can eczema herpeticum spread to the eyes?
Yes, if the virus reaches the eyes it can cause a serious infection that requires immediate assessment by a specialist to protect vision.
Why do my herpes sores take so long to heal?
If your immune system is less active, it cannot clear the virus as efficiently, meaning the sores may persist for several weeks.
Is eczema herpeticum contagious to others?
The virus is highly contagious and can be passed to others through direct skin contact or by sharing towels and bedding.
Should I stop using my eczema creams during an outbreak?
You should continue to moisturise but be careful not to contaminate your cream pots by touching them after touching a sore.
Can stress make a herpes infection worse for someone with eczema?
Stress can trigger both an eczema flare and a herpes outbreak, potentially leading to a more severe combined skin reaction.
What does a punched out blister look like?
These are small, circular sores that look as though a small piece of skin has been removed, often appearing in clusters.
Are there vaccines to prevent severe herpes outbreaks?
There are currently no vaccines available in the UK to prevent common herpes simplex infections or their complications.
