Division of Infectious Diseases


The Division of Infectious Diseases is part of the Department of Medicine at Oregon Health & Science University.  We are a group of academic physicians, allied health professionals and nurse practitioners specializing in the diagnosis and treatment of infectious diseases and related disorders.

We also offer a fellowship training program to those seeking a career in Infectious Diseases with two pathways: basic laboratory research and clinical investigation.

ID Faculty Spotlight

Holly Villamagna, MD

Tell us a little about your time at OHSU and your interests in ID?

I am a first-year faculty member interested in medical education, infection control, and public health (clearly, very narrow interests!)

What are you currently working on?

In addition to seeing patients on the general ID consult service, I am an IDSA Leadership in Epidemiology, Antimicrobial Stewardship, and Public Health (LEAP) fellow. As part of the program, I am collaborating with the Oregon Health Authority to study risk factors for COVID-19 outbreaks in long-term care facilities as well as gaining hands-on experience in infection control at OHSU and the VA. I am also working on designing and evaluating infectious diseases simulation lab curricula for medical students.

What about outside of work?

Outside of work, you can find me training to (slowly) run marathons, riding my Peloton bike, baking cookies, dragging my husband on adventures, and never sitting still.

What do you like about living in Portland?

I moved to Portland from Las Vegas, so the cooler weather, beautiful trees, and parks are my favorite part of the city!


The Division of Infectious Diseases clinic offers these services and more to those referred by a health care professional:

  • Consultation and treatment for adults with infectious diseases
  • Consultation and treatment for transplant recipients and other immunocompromised hosts with infection
  • Consultation and treatment of orthopedic and neurosurgery infections in multidisciplinary surgical-ID clinics
  • Management of patients on home IV antibiotics with orthopedic and neurosurgery infections

A message from the Division

We in the Division of Infectious Diseases are committed to taking concrete steps to foster diversity, equity, and inclusion. We are saddened, horrified, angered, and galvanized by the murders of George Floyd, Breonna Taylor, and Ahmaud Arbery, among the countless others driven by racism. These, along with the disproportionate impact of the COVID-19 pandemic on Black, Indigenous, Latino/LatinX, and other people of color, have compelled us to heighten our focus on structural racism, disparities, and inequities, and their relation to our clinical, research, and educational missions. We acknowledge the systemic failures that have brought us to this point and that it is our responsibility to develop and implement long-overdue measures aimed at correcting those failures. 

As a Division, we stand against racism in any form and we stand with those in our community who have suffered the effects of marginalization and discrimination. With intention, we will work to ensure that our clinical, educational, and research activities reflect the values of diversity, inclusion, and equity we espouse. We pledge to do our fullest in support of OHSU’s goal of combatting structural racism and becoming an anti-racist institution (OHSU standing up against structural racism). We support the response to the death of George Floyd from the Infectious Diseases Society of America (IDSA) and the HIV Medical Association (HIVMA) (IDSA/HIVMA statement) that structural changes, including within the healthcare system, are urgently needed to eliminate racism and health disparities.

Over the coming months, we will develop and share our specific plans to those ends. Through this work, we will add our voice to the larger effort of moving towards a more equitable and just society.
