Persons with atopic dermatitis or eczema, regardless of disease severity or activity, may develop eczema vaccinatum if they or their close contacts receive the smallpox vaccine. According to current recommendations, a preexposure vaccination program should identify these persons and exclude them from participating.
To determine the prevalence of diagnosed atopic dermatitis and eczema in a defined population and assess the sensitivity of screening questions to identify patients who have received these diagnoses.
Population-based prevalence survey and telephone interview.
14 ZIP code regions in Wisconsin.
Persons given a diagnosis of atopic dermatitis or eczema in 2000 and 2001 were identified from a population-based cohort. Persons with a history of atopic dermatitis diagnosed since 1979 were eligible for the telephone survey.
Prevalence of diagnosed atopic dermatitis or eczema; proportions of respondents able to recall a past diagnosis of atopic dermatitis, eczema, or recurrent rash.
The prevalence of atopic dermatitis or eczema diagnosis in 2000 or 2001 was 0.8%. At least 2.4% of the cohort would be ineligible for smallpox vaccination because of active skin disease in themselves or household members. Among 94 adult respondents with atopic dermatitis, 55 (59%) correctly self-reported skin disease. Seventy-nine (60%) of 133 household contacts of adults with atopic dermatitis correctly reported the presence of skin disease in a household member. Parental recall of skin disease in children with atopic dermatitis was 70% (123 of 177).
Identifying dermatologic contraindications to smallpox vaccination by relying only on a self-reported history of rash illnesses is likely to miss a substantial proportion of individuals who should not receive smallpox vaccine in a preexposure vaccination campaign.
People with a history of atopic dermatitis or eczema in themselves or their close contacts should not receive preexposure smallpox vaccination because of the risk for eczema vaccinatum.
This population-based study suggests that about 40% of people would not correctly report that they or a close contact has these skin conditions even though medical records confirm that they do.
Relying on patient self-report about dermatologic contraindications to smallpox vaccination would miss a substantial proportion of people with true contraindications.
