Most infections can be treated by primary care physicians, but sometimes a primary care provider will refer patients for consultation with an infectious disease specialist. People are referred for this service when an infection:
- is difficult to diagnose
- is persistent and won’t go away
- does not respond to treatment
- is a chronic condition (such as HIV/AIDS) that requires ongoing, specialized care.
Infectious disease specialists also see healthy people who plan to travel abroad where the risk for infection is higher.
