This is a common question that we often get. If the mask is worn correctly and you use other safety precautions (such as washing your hands regularly) it can assist in preventing the spread of germs and viral infections. We are not stating that wearing a mask is a cure and you will be 100% safe from contracting or spreading a virus however there is nothing out there that will 100% cover you (even a vaccination). There are several scientific studies supporting the use of face masks being highly effective in preventing the spread of germs and viral infections.
