Answer

The estimated incidence of systemic sclerosis in the United States is 20 cases per million population, and its prevalence has been estimated at 276 cases per million population, although the reported prevalence varies depending on the methodology used and the targeted population. [22, 23, 24] An increased systemic sclerosis incidence and prevalence has been evident in the last 50 years. Although improved diagnosis and increased survival rate can partially account for this observation, it appears that there has been a real increase in its incidence.
