Questions to Ask Your Infectious Diseases Specialist

Getting Referred
In Pakistan and many other countries, the usual route to a Infectious Diseases specialist is through a family physician or general practitioner, who can start tests and write a referral. Large teaching hospitals and specialist centres also run outpatient clinics. In an emergency, go straight to the nearest emergency department.
