Perhaps you should try some spelling variations:
"communicated diseases" » "complicated diseases", "communicable disease", "communicate disabled", "communicable diseases", "complicated diseasess", "communicate states"
"complicated diseasess" » "complicated diseases", "complicate disease", "complicated business"
"communicated disease" » "communicable disease", "complicated diseases", "communicate state"
"communicable diseases" » "communicate diseases"

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 ("communicated disease"))) OR ((("communicated diseases") OR ((("complicated diseasess") OR ("complicated cases")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"communicable diseases\") or (\"communicated disease\"))) or (((\"communicated diseases\") or (((\"complicated diseasess\") OR (\"complicated cases\"))))))".
• Removing quotes may allow a broader search: (((( communicable diseases ) or ( communicated disease ))) or ((( communicated diseases ) or ((( complicated diseasess ) OR ( complicated cases )))))).
• Adding a wildcard symbol may retrieve word variants: (((("communicable diseases") or ("communicated disease"))) or ((("communicated diseases") or ((("complicated diseasess") OR ("complicated cases"))))))*.
