Perhaps you should try some spelling variations:
communicated diseases » communicable disease, communicate disabled, communicate discover
communicate diseases » communicable disease, communicate disabled, communicate discover
complicated diseases » complicated cases, complex diseases, mediated diseases
communicated disease » communicable disease, communicate state, communicated vision

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((( communicable diseases ) OR ((( communicate diseases ) OR ( complicated diseases ))))) OR ((( communicated diseases ) OR ( communicated disease )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( communicable diseases ) or ((( communicate diseases ) or ( complicated diseases ))))) or ((( communicated diseases ) OR ( communicated disease ))))".
• Adding a wildcard symbol may retrieve word variants: (((( communicable diseases ) or ((( communicate diseases ) or ( complicated diseases ))))) or ((( communicated diseases ) OR ( communicated disease ))))*.
