Infectious Diseases and Travel Medicine

In addition to general internal medicine practice, Drs. Eggena and Liechty provide inpatient and outpatient infectious disease (ID) consult services and outpatient travel medicine consultations. They also provide comprehensive HIV disease prevention and management services and treatment for hepatitis C. ID consultation patients are referred to the practice by primary care clinicians as well as by surgeons and other specialists. Patients are welcomed to request pre-travel consultations without referral from another provider.

New medications for hepatitis C have transformed the disease into an almost uniformly curable condition. If you are interested in infectious disease services at Pen Bay Medical Center, please discuss a referral with your primary care provider.
