Infectious Diseases

The Infectious Disease Unit comprises five full-time faculty active in patient care, teaching and research.  The Unit consults on hospitalized patients and outpatients with a wide range of infectious diseases.  Most of the approximately one hundred new consultations seen monthly are from the Medical and Surgical services; a few are from the Pediatric and Obstetric services.  Usually about twenty patients are being followed at a time. Each member sees outpatient consults and follow-up of discharged inpatients one half- day per week. Drs. Falsey and Walsh research involves the epidemiology, immunology and clinical characteristics of viral infections and vaccine development for respiratory syncytial virus, influenza virus, and other respiratory viral pathogens.  The laboratory’s work involves viral culture methods, virus gene cloning, and immunochemistry of viral proteins, including techniques of gel electrophoresis, Western blotting, RT-PCR, immunofluorescence, solid phase immunoassays, and some experimental animal research.

Medical residents on this rotation share the consultations and follow-up with Infectious Disease fellows and/or fourth-year medical students when they are on the service.  Residents learn through case-based teaching, guided independent reading and didactic sessions on Infectious Disease topics.  This rotation is available for up to three residents at a time.

Clinical Activities:

The Rochester General Hospital Department of Medicine’s full time Infectious Diseases Unit provides comprehensive inpatient and outpatient consultative services for patients with acute and chronic infectious diseases. The five staff physicians, are board certified in Internal Medicine and Infectious Diseases. The primary clinical activities are inpatient consultation to adult medical and surgical services, including the Medical, Surgical and Cardiothoracic Intensive Care Units.

Administrative Activities:

Dr. Yamshchikov directs the Rochester General Hospital Infection Control and Epidemiology program. This hospital wide program is staffed by three infection control nurses and collaborates with other hospital departments such as nursing, employee health and administration. In addition, the staff directly interacts with the County and State Health Departments and the Center for Disease Control and Prevention in Atlanta.  Dr. Laguio-Vila directs the Antibiotic Stewardship Program along with two pharmacists dedicated to the program. Daily ASP rounds are done by the team, supplemented by other members of the Infectious Diseases physicians.

Teaching Activities:

Each of the physicians participates in the Rochester General Hospital Residency teaching program and in the University of Rochester’s medical student education and infectious diseases fellowship programs.

Research Activities:

Research programs are directed by Drs. Falsey and Walsh with an emphasis on the study of respiratory viral infections, specifically Respiratory Syncytial Virus and influenza virus in elderly persons. Funding for this research is principally from the National Institutes of Health. Dr. Murata's research involves mechanisms of antimicrobial resistance, and his work is performed at the University of Rochester.
