Hi, if the rash is still visible after 15 days of antifungal treatment, tinea would usually have shown more improvement by now. Psoriasis is possible and won't respond to antifungals at all.
Regarding
HIV â skin rashes can be an early symptom, but they're usually accompanied by fever, swollen lymph nodes and fatigue. To rule it out completely, a 4th gen HIV test at 28 days post-exposure would be advised.
Next Steps
Feel free to consult me on Practo with the pics for a proper diagnosis and treatment plan.
