The risk of progression to severe COVID-19 depends on the quantity of underlying medical conditions and how controlled the medical conditions are. * When assessing risk factors, prescribers may want to consult Ontario Health Recommendations for Antiviral Therapy for Adults with Mild to Moderate COVID-19 (April 2024). Examples of risk factors include: Vaccination Status: - Have never received a COVID-19 vaccine Medical Conditions: - Active tuberculosis (treated or untreated) - Cerebrovascular disease - Chronic kidney disease, especially CKD stage 4 or 5 and dialysis - Chronic lung diseases, limited to: asthma, bronchiectasis, chronic obstructive pulmonary disease, interstitial lung disease, pulmonary embolism, pulmonary hypertension - Chronic liver diseases, limited to: cirrhosis, non-alcoholic fatty liver disease, alcoholic liver disease, autoimmune hepatitis - Cystic fibrosis - Diabetes mellitus, type 1 or type 2 - Disabilities and developmental delay, including Down syndrome - Heart conditions (e.g., heart failure, coronary artery disease, cardiomyopathies) - Mental health conditions, limited to: mood disorders (including depression), schizophrenia spectrum disorders - Neurologic conditions that cause an inability to control respiratory secretions or communicate disease progression (e.g., cognitive disorders such as Alzheimer-type dementia) - Obesity (body mass index above 30kg per m2) - Pregnancy or recent pregnancy (42 days post-partum/end of pregnancy) Note for consideration: Certain medical or social vulnerabilities may confer an increased risk of disease progression because affected individuals may experience challenges in recognizing, communicating or acting on progressive COVID-19 symptoms. People who are at a high risk of poor outcomes from COVID-19 based on social determinants of health should be considered priority populations for access to antivirals. Individuals at high risk include Indigenous people, Black people, other members of racialized communities; people experiencing intellectual, developmental, or cognitive disabilities; people who use substances regularly (e.g., alcohol); people who live with mental health conditions; and people who are underhoused.
