What Causes Loss Of Taste Post A Bout Of Fever?

I have had the flu (fever, chills, aches, chest cough) and recovered then about a week later came down with a very bad cold, very bad head congestion, headaches, chest cough (again), runny nose, loss of appetite, and now, I cannot taste anything. Most of the symptoms are better now though my head is still congested and my ears feel plugged up, I am eating a bit more. Still producing mucus. I am into day 6 with this and am concerned about the loss of taste.
