My 6 month old will not eat solids after being ill after chickenpox. Help what do I do?

My daughter has been a great eater since I began weaning her at 4 months. She would eat anything and everything. Recently she has had chicken pox and she went completely off any solid foods. Now she is better she still will not eat solids. She just clamps her month shut and even refuses to look at me. How can I get my daughter to be the brilliant eater again?
