Thank you for your query,
is highly contagious the lesions may be due to it.
And the lesions require local antibiotic
cream applications in addition to oral antibiotics
if the lesions are extensive or associated with fever.
Clinical examination is important to diagnose the skin conditions.
So I advise you to consuot your Pediatrician
for the examination of skin lesions and proper treatment.
Hope I have answered your query.
