New cases of lupus
How many people get lupus every year.
More than 8 per 100,000 in women and more than 1 per 100,000 men develop lupus every year.
It is worrying that the incidence of lupus has markedly increased in recent years - a recent study compared the incidence (new cases per year) of lupus between 1950-1979 and 1980-1992 in Olmsted County, Minnesota: In 1950-79 the incidence in females was 2.47, it increased to 9.4 in 1980-92 (more than trippled). Similarly, in males, it increased from 0.5 to 1.54. Moreover, many cases with a milder disease or atypical presentation remain undetected. In this study, the prevalence (i.e., total cases in the population) was 130 per 100,000. The incidence and prevalence is higher in certain ethnic groups - e.g., African-American women appear to have a higher incidence.
