Can chickenpox start out on the area near navel of a child?

The first... ...Lesion can be anywhere, but if there are more than 3 lesions and they are all clustered together, chickenpox would not be my first choice.
Possible. The rash usually starts on the trunk and spreads to head (face and scalp). It begins with crops of red bumps which rapidly become little fluid-filled blisters which do not have an indentation in the center. Children usually first have fever, malaise, and loss of appetite about a day before the rash begins. The rash continues in new crops of lesions for 3-4 days. They itch and may be in mouth.
