Also searched as: toddler hair loss after feverchild hair loss after illnesskids hair falling out after being sick

The American Academy of Pediatrics' HealthyChildren site says physical stress such as high fever, hospitalization or surgery can make a child shed more hair over a few weeks or months; it thins the hair but does not cause bald patches and gets better on its own.
