Infectious Diseases

The Division of Infectious Diseases at Mount Sinai Morningside applies a wide variety of clinical and research expertise to patient care. We provide insight into diagnostic test results, help determine the best treatment option and management of specific infectious diseases, and are experts at preventing recurring infections.

Our infectious diseases specialists work with your general internist or primary care physician to address your overall health care needs. Our services focus on general infectious diseases and related disorders, immunocompromised patients, travel-related issues and infections, and HIV/AIDS.

Within our outpatient clinic, outpatient parenteral antimicrobial therapy (OPAT) is available for medically stable patients to complete intravenous antibiotics. The OPAT clinic allows our patients to avoid a hospital stay or decrease its length. We work to ensure safe and effective implementation of parenteral antimicrobial services for patients within two weeks after hospital discharge. We also arrange initiation of antibiotics and vascular access from the clinic for stable patients referred by the Emergency Department within 24-48 hours after discharge.

Our providers are also dedicated to enhancing your recovery. We monitor patients on OPAT for clinical improvement and side effects. We then determine the appropriate therapy, duration, and efficacy of treatment. Lastly, we evaluate vascular access and assess weekly labs to ensure that you receive the correct dose and avoid side effects.
