Clarification on a Few Protective Measures Against the Novel Coronavirus (COVID-19)

You may be anxious and have questions about the current coronavirus disease (COVID-19) crisis. A lot of—sometimes inconsistent—information has been shared these past few days on how to slow the spread of the virus. We feel that the facts need to be straightened out.

  • Wearing a medical mask is not recommended for people who don’t have a fever or respiratory symptoms. The mask is only useful in slowing the spread of the virus when it is used by a symptomatic person. Reusable fabric masks can be used in public places where social distancing is impossible. Please follow your healthcare team’s recommendations regarding masks.
  • Testing is limited to symptomatic individuals. If you don’t have a fever or respiratory symptoms (cough, sore throat), you don’t need to get tested for coronavirus. If you’re not sure whether you should get tested, call 1-877-644-4545.  You can also complete the Government of Canada’s self-assessment tool.
  • According to the Institut national de santé publique du Québec, there is no evidence that indicates that tap water is a transmission route for the novel coronavirus. The water purification process removes the vast majority of micro-organisms. 
  • The World Health Organization (WHO) issued a warning about a potential risk associated with taking ibuprofen (Advil, Motrin) to relieve COVID-19 symptoms. As a precaution, the WHO advises against using ibuprofen when showing COVID-19 symptoms.
  • There is no contraindication with regard to acetaminophen (Tylenol). Remember that this drug doesn’t interact with the Dexcom G6 and FreeStyle Libre CGMs. So, if you take acetaminophen, you can still rely on your CGM readings. However, there is a possible interaction with older sensor models (e.g., Dexcom G5). Based on laboratory studies, high doses of aspirin (more than 650mg) could falsely decrease the values indicated on the Freestyle Libre monitor, while high doses of vitamin C (more than 500mg) could falsely increase the values indicated.
