#3 DIY Mask, better than nothing!

According to a study on influenza by the Public Health England (PHE), surgical masks and homemade masks are both able to prevent transmission of microbes expelled from cough or sneeze, but the effectiveness of homemade masks are only one-third of a proper surgical mask. DIY masks should hence be only considered as a last resort, while the best method of hygiene protection and disease prevention is to avoid going out if you do not have a surgical mask.
