Lori Wells (from left) and her daughters Grace, 13, and Claire, 18, ride bikes in their Mullica Hill neighborhood on Tuesday. Claire has Down syndrome, and because of her history of pneumonia, the family is taking particular care with social distancing while at the same time trying to remain active with family hikes and bike rides.

Coronavirus and the measures to control it are posing extra challenges to many people with special needs and their families, and to the organizations that serve them. Some with disabilities could be particularly vulnerable should they catch the virus. And the practice of social distancing conflicts with decades-long efforts to include all people with intellectual disabilities as fully as possible in their communities.
