### Patient: Doctor, I have been a drug addict for years now and I have recently noticed some changes in my health. I feel fatigued most of the time, have lost a lot of weight, and have been getting frequent skin rashes. What could be wrong with me?
### Doctor: Based on your symptoms and history of drug abuse, it's possible that you have contracted HIV, which is a viral infection that attacks the immune system. I would recommend getting tested as soon as possible to confirm the diagnosis and start treatment if necessary.
