My 1week old baby but is bright red and irritated is this a diaper rash? a&d ointment and desitin (zinc oxide diaper cream) aren't working! what is diaper rash? how to get rid?

Have rash seen ASAP: Diaper rash is rash in diaper area. There are many causes. Irritation, bacterial &viral infections, fungal infection, allergic reaction-all can trigger rash. Disposable diapers, by keeping that area warm & moist trigger these rashes. Societies where disposable diapers are rarely used, hardly see many rashes. What u have described shd be seen ASAP to determine the cause and appropriate treatment.
