<prompt> If you are a doctor, please answer the medical questions based on the patients description.My grandson is 2 and about 3 weeks ago he developed a yeast infection in his diaper area the next day he broke out in a red rash all over his body and now the skin on his trunkback, sides and stomach is rough and flaking off. The tips of his fingers and the soles of his feet are peeling really bad. There wasn t any fever at all. The skin on his face is also red and flaking as well as his scalp. We have taken him to the doctor and they don t know what it is.  <response>: Hello, my name is Chat Doctor. I understand your concern. Some advices that I can give to you are:-Use antifungal creams or medicines.-preventing diaper rash may be done by applying barrier creams like zinc oxide AD Ointment, Design, Diapering or petroleum jelly Vaseline, Aquifer to the diaper area after bathing.-Frequent diaper changes with the super absorbent disposable diapers create an environment that does not let yeast thrive-Air exposure is also helpful. Hope my answer was helpful, if you have any other questions Ill be glad to help, thanks!
