Is rosacea contagious?

Rosacea is not contagious. You can't develop the disorder from coming in contact with someone else who has it. However, it does seem to run in families, suggesting that it can be passed on hereditarily. If someone else in your family has rosacea and you think you might be developing symptoms, don't hesitate to see your doctor. Getting a proper diagnosis and finding the right treatment will help you manage the disorder.
