There are different categories of populations at risk:

• People who have affected people in the family because there is a genetic factor. In 30 to 40% of cases, there are several affected people in the same family.
• There is a predominance among women, although it affects both sexes.
• The disease often begins in adolescence or in young adults.
• Verneuil’s disease is rare before puberty and after menopause.
• The quality of hygiene is not in question in Verneuil’s disease. It is not a question of a lack of hygiene or an inadequate hygiene.
