Program Details

The Infectious Diseases Fellowship at Penn State Health Milton S. Hershey Medical Center strives to educate the next generation of infectious diseases leaders by providing an intellectually exciting, diverse and supportive environment in which trainees can develop the skills necessary to succeed in clinical care, education and research.

During their training, fellows will develop expertise in caring for patients with the following conditions in both the inpatient and outpatient settings:

  • General infections including COVID-19 and other respiratory virus infections, skin and soft tissue infections, cardiac device infections, blood stream infections, infections related to complicated wounds, tick borne infections, travel-related infections, pneumonia, fever of unknown origin, CNS infections, postoperative infections, tuberculosis, and many other types of infections
  • People living with HIV, seen in comprehensive care clinics funded primarily by Ryan White HRSA grants, providing services at six regional sites and following over 700 patients
  • Infections related to solid organ transplant through a dedicated consult service
  • Infections in patients with cancer or who have undergone a hematopoietic stem cell transplant through a dedicated consult service
  • Complex bone and joint infections through a dedicated consult service

Fellows will also participate in health system and public health-oriented services including antimicrobial stewardship, hospital epidemiology and infection prevention, employee health, and special pathogens preparedness initiatives.

In addition to these clinical activities, fellows are involved in research and educational conferences that are aimed at providing a foundational knowledge of clinical research and critical literature review. Interested fellows will have the opportunity to enroll in Penn State College of Medicine programs to achieve a Graduate Certificate in Clinical Research or a Master of Public Health.

The program follows the Infectious Diseases Core Curriculum in the training of infectious diseases fellows, in preparation to sit for the ABIM Board Examination in infectious diseases. Flexibility exists in the curriculum to tailor clinical or research months to an individual fellow’s interests and career goals.

Inpatient Consults at Penn State Health Milton S. Hershey Medical Center

Inpatient consults at Hershey Medical Center are the core academic rotations for the fellowship program and are split to include rotations on the general infectious diseases, solid organ transplant, stem cell transplant and orthopedic infectious diseases services (view full list of services). Fellow experience can be tailored with additional elective time on any of the four services, in line with each trainee’s individual goals.

The general infectious diseases team consists of an attending physician, one fellow, medical residents, students and members of allied health services, such as pharmacy. The fellow is the leader of the team, responsible for assessing patients, helping make clinical management decisions and providing education to enthusiastic residents, students and other learners.

The orthopedic, solid organ transplant, and stem cell transplant subspecialty teams consist of an attending physician, advanced practice providers and, on some months, a fellow. Integrative and collaborative learning is stressed on these rotations, and fellows will see patients together with both the infectious diseases attending and the primary team attending in the inpatient and outpatient settings. Subspecialty specific education will be provided and fellows will also have the opportunity to attend primary team conferences and education sessions relevant to their patients.

Fellows’ Continuity Clinic

Each Infectious Diseases fellow is assigned to one half-day continuity clinic per week throughout their two years of clinical training. Patients consist of a mix of persons living with HIV (PLWH) and general infectious diseases patients, including care of patients as part of the outpatient parenteral antibiotic therapy program (OPAT).

Fellows are the primary provider for their patients and are supervised by a designated faculty member who is consistent throughout their training. On average, fellows see six to eight patients in clinic each week, with one to two of these slots reserved for new patient referrals.

Inpatient Consults at UPMC Pinnacle Harrisburg Hospital: Elective

UPMC Pinnacle Harrisburg Hospital is a large, community-based hospital in downtown Harrisburg, Pa., approximately 12 miles from Hershey Medical Center. This rotation allows interested fellows to gain more experience in a community ID setting. Fellows interested in a career outside of academic medicine often find this rotation particularly helpful. It can be fast-paced, with high volume, and offers plenty of interesting pathology. Fellows working on the Harrisburg Hospital infectious diseases service perform in a similar way to the Hershey service, seeing new consults and hospital follow ups throughout the week under the supervision of an ID attending.

Outpatient Infectious Disease Clinics: Elective

This rotation includes half-day clinic sessions to enhance the outpatient infectious diseases experience provided by the fellow continuity clinic. On this elective, in addition to seeing PLWH and general infectious diseases patients, fellows have an opportunity to see subspecialty patients in orthopedic, solid organ transplant and bone marrow transplant infectious diseases. In addition, fellows are able to travel to some satellite clinics to see PLWH in underserved rural communities. A hepatitis B and C clinic experience with the hepatology service may also be available for interested fellows.

Inpatient/Outpatient Pediatrics Infectious Disease Elective

This rotation exposes fellows to the full spectrum of pediatric infectious diseases and includes inpatient consultations as well as selected outpatient clinics both in general pediatric infectious diseases and HIV/AIDS.

Antimicrobial Stewardship Rotation

The Infectious Diseases Fellowship implemented an antimicrobial stewardship rotation for all fellows beginning in 2015, which is overseen and instructed by Dr. Michael Katzman, the director of the Antimicrobial Stewardship Program (ASP). Dr. Katzman is a favorite among fellows and has been elected to the ranks of Distinguished Educators by Penn State College of Medicine. On this rotation, fellows are immersed in the ASP process and spend time reviewing treatment guidelines, analyzing primary literature, and closely collaborating with providers throughout the institution to improve the care of individual patients and limit the rates of antimicrobial resistance.

Hospital Epidemiology and Infection Prevention: Elective

Fellows are required to complete the Infectious Diseases Society of America (IDSA)-sponsored Infection Control Lecture series online; this is accomplished during a non-clinical rotation during the first year.

Interested fellows are also invited to attend weekly Hospital Epidemiology and Infection Prevention meetings, monthly Infection Control Committee meetings, and may choose to design an elective focused around a specific research project in this area.


The program recognizes the critical importance of interdisciplinary patient care with the help of colleagues in the Clinical Microbiology laboratory. In August of the first year of fellowship, an orientation to the clinical microbiology laboratory takes place with formal lectures and training over a two-week period. After this two-week period, fellows attend a weekly lecture conducted by the clinical microbiology team for ongoing learning.

In addition, microbiology rounds take place each week on Tuesday mornings, during which both faculty and fellows review the microbiology specimens for patients on service and other interesting specimens seen in the lab each week.

View a video from the American Society for Microbiology about a clinical microbiology lab.

Outside Rotations: Elective

Fellows with a particular interest in a clinical area may arrange to spend an elective period at an outside institution, including international or public-health-based rotations.
