<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello doctor, Ive been feeling really itchy lately and I have these red spots all over my body. I think I might have Chickenpox.  <response>: It is possible that you have Chickenpox, but we need to perform a complete physical skin exam to confirm the diagnosis. In addition to that, we also need to do an HIV screen to rule out the possibility of HIV infection.
