Several people wear masks when they leave their houses, due to the coronavirus. Wearing masks helps slow the spread of COVID-19 and two studies show which fabrics work best. Homemade masks can help block aerosols and some fabrics do this better than others. A team tested different fabrics and found two fabrics together worked best. The fabrics are cotton with silk or chiffon and the combination blocked most particles. It kept out nine out of 10 particles the team reported. The mask also needs to fit the face tightly as gaps can let virus particles in. They measured how many particles got through and the tighter fit helped so it kept more particles out. Wearing a mask protects you and also protects others.
