Perhaps you should try some spelling variations:
"communicable diseasess" » "communicable diseases", "communicable disease", "noncommunicable diseases"
"communicated diseases" » "communicated disease", "communicable diseases", "communicable disease"
"complicated diseases" » "complicated cases", "complex diseases", "mediated diseases"
"communicate state" » "communicate strategy", "communicating state", "communication state"

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: (((((("communicated diseases") OR ("communicable diseasess"))) OR ("communicate state"))) OR ("complicated diseases")).
• Removing quotes may allow a broader search: (((((( communicated diseases ) or ( communicable diseasess ))) or ( communicate state ))) or ( complicated diseases )).
• Adding a wildcard symbol may retrieve word variants: (((((("communicated diseases") or ("communicable diseasess"))) or ("communicate state"))) or ("complicated diseases"))*.
