Clinical Services

The Chronic Viral Illness Service (CVIS) aims to provide exemplary care and support to patients living with HIV, HCV and other chronic viral infections. A multidisciplinary and patient-centred approach as well as the principles of chronic disease management are foundational to our service.

CVIS Healthcare Services

The CVIS offers diagnostic and treatment services for adults who are infected with one or more of the following infections: HIV (human immunodeficiency virus), HCV (hepatitis C virus), and HPV (human papilloma virus). Also, patients with co-infections and other chronic morbidities are provided care.


Five services are provided by the CVIS to adults who are at risk for or infected with, HIV, HCV and HPV. The services are:


  1. Outpatient consultations (referrals from other physicians) regarding the diagnosis, assessment and treatment of adults with HIV, HCV, HPV or other morbidities (e.g., steatosis) common to patients living with these chronic viral infections.
  2. Scheduled follow-up visits with a physician or other healthcare provider
  3. Unscheduled emergency or semi-urgent visits (“Walk-ins”)
  4. Inpatient consultations for people hospitalized at the MUHC
  5. Testing for HIV, hepatitis and sexually transmitted infections (STI), or to request medications to prevent HIV infection for people:
    • Who may have been exposed to HIV, either in an occupational or non-occupational setting (e.g., during sexual relation). This is referred to as post-exposure prophylaxis or PEP.
    • Who may be exposed to HIV (i.e., during sexual or injection behaviours). This is referred to as pre-exposure prophylaxis, or PrEP.
    • These services are primarily for partners of HIV-infected patients followed at the CVIS

Our clinical services include:

  • Initiation and follow-up of treatments, including for HIV and HCV infections and their complications
  • Assessment by pharmacists of drug-drug interactions, therapeutic drug monitoring, and adherence to treatment regimens
  • Preventive interventions and care such as screening and vaccinations, when appropriate
  • Mental health assessment and treatment by our psychiatrist and psychologist
  • Social work and social assistance
  • Evaluation of nutritional status and related advice
  • Complex interventions such as wound care, chemotherapy and blood transfusions as provided by nurses
  • Diagnostic and treatment services for HPV care are in development
  • Hospitalization, when needed, is available through the MUHC-Glen Site. On rare occasions, patients will be admitted to the Montreal General Hospital, the Montreal Neurological Institute or other institutions in the MUHC network.
