What is the difference between a cold and the 'flu?

Answer

John -  Itís very difficult to say.  Many different viruses cause flu-like symptoms and on the other side, flu causes a range of symptoms.  So, without testing somebody serologically, we can't really tell whether somebody has got flu or not.
