A recent survey of 2,052 rosacea sufferers conducted by the National Rosacea Society provides evidence that this chronic skin condition runs in families, and that people of some nationalities are more likely than others to develop the disorder.

Nearly 40 percent of the respondents indicated they had a family member who also suffered from rosacea. For 27 percent, that family member was a parent. Eighteen percent had a brother or sister suffering from rosacea, while 13 percent had a grandparent with the disease and 16 percent had an aunt or uncle who was affected.
