What is eczema herpeticum and who is most at risk?

### What is Eczema Herpeticum? Eczema herpeticum is a rare but serious skin infection caused by the herpes simplex virus (HSV). It occurs when the virus infects skin that is already damaged by eczema. This condition can cause painful blisters and can spread rapidly, potentially affecting vital organs and becoming life-threatening. ### Who is Most at Risk? Infants, children, and adults with atopic dermatitis or other forms of eczema are most susceptible to eczema herpeticum. People with compromised skin barriers, such as those with contact dermatitis or seborrheic dermatitis, are also at higher risk. ### Symptoms The first signs usually appear 5 to 12 days after exposure to HSV. Symptoms include painful red, purple, or black blisters, often on the face and neck but can appear anywhere on the body. Other symptoms may include high fever, general discomfort, and enlarged lymph nodes. ### Prevention and Treatment To prevent eczema herpeticum, avoid direct contact with cold sores and practice good hygiene. If symptoms appear, seek medical attention immediately. Treatment typically involves antiviral medications like acyclovir and may require hospitalization in severe cases. Early treatment is crucial to prevent complications such as secondary bacterial infections or the virus spreading to the eyes or brain. ### Conclusion Eczema herpeticum is a medical emergency that requires prompt treatment. Understanding the risks and symptoms can help in early diagnosis and effective management.
