Hi dear, Thanks for choosing Health care magic. I suspect your daughter has Ringworm, it’s common mild fungal infection and it usually presents as you have stated in your question. It could also be Tenia versicolar infection which again is a fungal infection. both of them are treated with an over the counter anti fungal creams. Since you mentioned that your daughter is now perfectly fine and she has no other symptoms other than these circles then i highly doubt it s related to her previous infection. I suggest that you get an anti fungal cream such as clotrimazole and apply it around the affected areas twice a day for at least 2 weeks. Important note: Skin conditions are not easy to be diagnosed online without full inspection, you could also consider sending a picture of the effected area here on healthcaremagic. Some skin diseases mimic each other and only by running some tests a Doctor can identify the cause and thus give proper treatment. Therefore, even with my suggestion given above i still advice you to take your daughter to a pediatrician or a dermatologist so that she can be checked well and give a confirmation for my diagnosis. Hope this helped. If you have more questions don t hesitate to ask. I wish you and your daughter all the best.
