People who have one or more chronic diseases or a weakened immune system are at increased risk of complications (hospitalization, admission to intensive care and death) from infection with COVID‑19.
Here is a list of chronic diseases and health conditions that may increase the risk of developing serious complications from COVID‑19:
- chronic diseases:
- heart or lung disease,
- liver (including cirrhosis) or kidney disease,
- medical condition with decreased clearance of respiratory secretions or a risk of aspiration;
- person receiving chemotherapy or radiation therapy;
- transplant recipient (including a bone marrow transplant);
- person who is taking corticosteroids;
- person who is taking immunosuppressants;
- person who is immunocompromised;
- person living with HIV;
- person who has anemia.
People with several of these factors as well as older age have a higher risk of developing a severe form of the disease. Furthermore, people who require regular medical follow-up or hospital care for their condition are considered the most vulnerable.
Recommendations for people who have chronic disease or a weakened immune system
People who have a chronic disease or a weakened immune system and their loved ones must
- follow the basic health directives at all times;
- minimize contact with people;
- avoid public places;
- otherwise, wear a mask or a face covering.
Irrespective of age, additional protective measures may be required for workers who have chronic disease or a weakened immune system. For example, encouraging people to work from home or, if telework is impossible, rigorously applying specific preventive measures in some workplaces.
