Question #59 asks "HAVE YOU EVER HAD OR DO YOU NOW HAVE" acne. If someone has acne now or ever has had acne (however minor) being honest says you answer "yes" to the question. A simple personal remedial statement on DoDMERB's form will clarify that the acne problem in question will have no effect on training, and he should be qualified without additional records or DQ's.
@NJROTC-CC, IMHO, I unfortunately do not agree with you statement "
My DS has some pimples, but my story - - and I am sticking to it - - is that he DOES NOT have a a "long term skin disease" as I understand that term. So the answer to Question No. 59 will be a very honest "NO". If he has too many pimples on the day of his DoDMERB exam, the doctors can deal with it as they see fit". It isn't what the examiner thinks, it is what may happen during initial training, maintaining grooming standards or wearing clothing or protective gear that may be an issue. And just FYI, be VERY careful using Wikipedia as it is not an acceptable source for referencing, people like you and I can modify, write "facts" and change the terms without any concrete evidence. That is why it is totally unacceptable for research papers or other scholastic or medical reference. The Mayo Clinic say "acne signs vary depending on the severity. 1. whiteheads, 2. blackheads, 3 papules, 4 pimples etc, etc". There is no mention of "long term skin disease" anywhere in the diagnosis or symptom sections.
Unless you are a doctor or a dermatologist, you are probably not qualified to say that as a universal statement, if Y then the correct answer is X. The candidate may have such a minor case and it be so intermittent that it is not going to be an issue, but to tell people listening here to ignore a possible problem, or make their own diagnosis is asking for future problems. Better to be forthright, do a remedial, have it in the record, and then not have to worry about it. Everyone is free to do as they want in answering DoDMERB questions, but I think to give advice based on Wikipedia is not prudent recommended advice. If in doubt use WebMD, TheMayoClinic, or the Physicians Reference Manual, those sites cannot be modified or added to by other than someone who is a doctor or research PhD.
