third generation like elsa?
Hello
Seborrhoeic dermatitis is very very common and as your dermatologist has said, is often caused by a fungal infection.
It does appear in advanced HIV disease but in my experience this occurs after several years at the very minimum.
I do not believe that you have HIV from the episode and it is probable that the oral tests are correct. Oral tests quite simply are not as good as blood tests so if you (or anyone else) is concerned regarding the possibility of HIV then a blood test - perferably at least 3rd generation but ideally fourth generation HIV tests are best.
I repeat though, I do not believe from what you have said that HIV is in the picture at all.
best regards, Sean
