The diseases will return, but it is likely they will not be as prevalent because of improved sanitation. Then your child would have to actually contract the disease. Then your child would have to have complications from what are (mostly) benign childhood diseases.

Chickenpox while uncomfortable, very rarely an actual health risk
"Rubella infection of children and adults is usually mild, self-limiting and often asymptomatic" as per Wikipedia
