…you would have a join table between illness table and customer table if looking at this due to the many to many relationships here, but that isnt important for the base concept of FKs.*
as a side note, is the image you supplied the data or the 3NF version? if it is the 3NF version it needs some more work before being fully in 3NF state :)
edit: [video this video goes over normalization pretty well imho worth a watch…
