Fellows’ training experiences benefit from general in-patient pediatric units; a pediatric emergency room; active bone marrow, liver, heart, and intestinal transplant services; general, orthopedic, neurosurgical and other subspecialty surgical services; and neonatal, cardiac, and pediatric intensive care units. Out-patient clinics for ambulatory patients are enhanced by more specialized experiences in international adoption and out-patient antibiotic management. Fellows spend at least one month in hospital infection control and one month in clinical microbiology /virology.
