Perhaps you should try some spelling variations:
"communicable disease" » "communicate disease", "comunicarle disease", "comunicables disease", "communicable diseases"
"comunicarse disease" » "comunicarse diseases"
"comunicarte disease" » "comunicarte diseases"
"communicative disease" » "communicative diseases"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("communicable disease") OR ("comunicarse disease"))) OR ("comunicarte disease"))) OR ("communicative disease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"communicable disease\") OR (\"comunicarse disease\"))) OR (\"comunicarte disease\"))) OR (\"communicative disease\"))".
• Removing quotes may allow a broader search: (((((( communicable disease ) OR ( comunicarse disease ))) OR ( comunicarte disease ))) OR ( communicative disease )).
• Adding a wildcard symbol may retrieve word variants: (((((("communicable disease") OR ("comunicarse disease"))) OR ("comunicarte disease"))) OR ("communicative disease"))*.
