Child Has Contagious Illness. Has A Red Swirly Lines Under Skin On Arms, Back, Buttocks, Legs. Had Strep Throat
Considering the details of what you describe and the contagious nature of the lesions, experienced by most of the child s classmates, its very reasonable to think of an infectious process.
Prednisolone to me will hardly be very appropriate at this point in time. Considering the fact that lesions have not been improving on treatment, and also the characteristics make this drug, under these circumstances not very appropriate.
I suggest this should be a fungal infection that s spreading. The presentation of the lesions are actually very peculiar is skin fungal infections (dermatophytes).
It would be rare that it should be a bacterial infection, this would have been certainly accompanied by a greater degree of inflammation, fever and much pain.
Viral infections could also present as such.
I suggest taking an appointment with a dermatologist for a proper clinical evaluation. Topical antifungal drugs could be used for now as you wait for an appointment with your dermatologist.
Thanks and best regards. Feel free asking further questions if need be,
