In a new global survey of more than 3,500 people with lupus released by the World Lupus Federation (WLF) for World Lupus Day,, nearly 7 in 10 participants responded that lupus hampers their mobility. The majority of survey respondents also reported they are limited from doing daily activities because of lupus, including limitations going up and down stairs (67%) and doing chores (69%) such as vacuuming or yard work.
