Here are the top three myths regarding COVID-19. 


Myth 1: Cloth masks are not effective in reducing transmission because virus particles are too small. 


A recent study proved that COVID-19 is spread through hundreds of droplets that were generated just by saying a short and simple phrase. The study also proved that nearly all the droplets were blocked from spreading while covering the mouth with a washcloth. A similar effect could be compared to wearing a face cloth mask. According to Tom Chang MD, wearing a cloth mask is a form of protecting ourselves and others around us by decreasing the spread and therefore decreasing the odds of contamination. 


Myth 2: I don’t feel sick, so I don’t need to wear a mask.


According to the studies regarding the latest science, transmission of COVID-19 typically originates from individuals who are asymptomatic or presymptomatic, and there are also those individuals who may never experience any symptoms. Wearing a face mask helps to minimize contamination and spreading.


Myth 3: I’ll get carbon dioxide poisoning by wearing a mask.


Up to date, Tom Chang MD points out, there is not enough evidence supporting that wearing a face covering will cause people to breathe in enough carbon dioxide that causes illnesses in individuals who don’t already suffer from a severe respiratory disease. If you’re wearing a face mask for short time durations, such as while in the grocery store or at the doctor’s office, then this should not be harmful. Normal respiration can still take place and carbon dioxide molecules are able to diffuse through masks.
