A new study on the global epidemiology of rosacea and acne offers a new estimate of how many people may have rosacea worldwide.¹

Researchers have attempted to determine the global prevalence of this widespread disorder for the first time.

Residents of New England appear to suffer the highest incidence of rosacea in the United States, while those in Hawaii may be affected the least, according to a geographic analysis of National Rosacea Society (NRS) membership data. 

Starting with the new decade, it is now estimated by the National Rosacea Society (NRS) that 16 million Americans suffer from the signs and symptoms of rosacea, and millions more may be in temporary remission.

A new study funded by the National Rosacea Society provides further evidence that rosacea may be far more common than widely believed, and also assesses the potential significance of sun exposure.

The recently completed study, presented at the 2008 British Association of Dermatologists meeting by Dr. Maeve McAleer and colleagues at Mater Misericordiae University Hospital and the School of Public Health and Population Science, University College, Dublin, found that 14.4 percent of 1,000 subjects examined in Ireland had rosacea.

The incidence of rosacea may be higher than widely believed, according to a preliminary study presented at the recent rosacea research workshop, sponsored by the National Rosacea Society (NRS) during the annual Society for Investigative Dermatology meeting. In addition, an ongoing Irish study found similar prevalence rates of subtype 2 (papulopustular) rosacea in both indoor and outdoor workers.
