It is no secret that social media and the internet have played a significant role in the spread of misinformation about the COVID-19 pandemic. We have all been exposed to a massive amount of information, and it can be hard to tell what is reliable and what is not. In an attempt to flatten the ‘infodemic’ curve, the World Health Organization has created a ‘COVID-19 Mythbusters’ guide. Listed below are a few COVID-19 mythbusters to help you stop the spread of misinformation!


FACT #1: The coronavirus disease (COVID-19) is caused by a virus, not by bacteria.

Although some people who become ill with COVID-19 can also develop a bacterial infection as a complication, COVID-19 is caused by a virus. Antibiotics do not work against viruses.

FACT #2: Using medical masks for a prolonged period of time does not cause CO2 intoxication or oxygen deficiency

While it can be uncomfortable to wear a mask for a long period of time, it does not lead to oxygen deficiency or CO2 intoxication. Ensure your mask fits properly and is tight enough that you can breathe normally. Disposable masks should not be re-used. Be sure to change or wash your mask once it becomes damp.

FACT #3: Vitamin and mineral supplements cannot cure COVID-19

Nutrients promote health and wellbeing, however there is no guidance on the use of these supplements to treat COVID-19.

FACT #4: Cold weather and snow CANNOT kill the COVID-19 virus, and COVID-19 CAN spread in hot and humid climates.

Social distancing, frequently washing your hands, and avoiding touching your eyes, mouth and nose are the best ways to protect yourself against COVID-19. There is no reason to believe that cold or hot weather can kill the new coronavirus (or any other diseases).

FACT #5: People should not wear masks while exercising.

During exercise, the most important preventive measure is to maintain physical distance. Sweat can cause a mask to become wet more quickly, making it more difficult to breath and promoting the growth of microorganisms.
