Persons most at risk to encounter severe complications have been identified by the Institut national d’excellence en santé et en services sociaux (INESSS, the scientific committee of the department of Health). According to the March 27, 2020 document, they have been identified as: 

• Persons of all ages suffering respiratory system diseases 

• Persons of all ages suffering from cardiovascular diseases

• Persons of all ages suffering from high blood pressure

• Persons with a disrupted immune system

• Persons over the age of 65

The CDC and the High Council of Public Health (France) have been targeting other groups. As a rule, the sicker an individual with numerous out of control conditions prior to being infected by SARS-CoV-2, the greater are the challenges once the infection has been detected.  

As of now, obstructive sleep apnea has not been the subject of a specifically published data. It has been however, linked to high blood pressure, atherosclerotic cardiac disease, (angina, infarct) and is often encountered in people over the age of 65. It is suspected — without any established proof up to date — that obstructive sleep apnea increases the risk of more serious infections.

Two drugs appear to interfere in a COVID-19 situation: ACEi and NSAID. The angiotensin-converting enzyme inhibitors (ACEi) used mainly for treating high blood pressure, diabetes related kidney problems and heart failure are suspected to aggravate the situation. However, experts are asking NOT to dismiss this important medication because of unclear data. If the situation arises, talk to your doctor
