baby boy is 13 months old he was on iv antibiotics for dengue fever . he got red rashes all over his genital and anal area. what ointment should I apply

A. hello...this would require proper check up to know why it's happening...allergy or something...this seems like a problem which should be seen by a medical professional....i would suggest you see a doctor to know if there is anything to worry about and to know why this is happening ..
