[Descriptive epidemiology and knowledge of erysipelas risk factors].
Few epidemiological data related to erysipelas or cellulitis is available in the literature. Descriptive data, such as incidence, has mainly been assessed in hospital settings, and exceptionally in the general population. In the only case-control study available, main risk factors for erysipelas of the leg were lymphoedema and the site of entry. Leg edema, venous insufficiency, and overweight were associated to erysipelas to a lesser extent. Given its high attributable risk, secondary prevention strategies targeted at toe-web intertrigo should be evaluated. Risk factors for severity are difficult to assess if they are transient - such as NSAIDs intake. A study on prognostic factors is needed before intervention strategies are tested in appropriate groups of patients.
