A nonproductive cough is a cough that does not bring up phlegm or mucus. It is also called a dry cough, and tends to irritate the throat much more than a productive cough (a cough that brings up phlegm and/or mucus) does.
There are several symptoms of the flu, or Influenza A. These symptoms include, fever, body aches, sore throat, headaches, nonproductive cough, nausea, and vomiting.
"Productive", when speaking of coughs, means "productive of mucus." If you're hacking up balls of phlegm, that's a productive cough. Certain diseases are associated with productive coughs, and others aren't. Flu is one of the ones that aren't as mucus-producing in most people.
