Severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) related disease, called coronavirus disease 2019 (COVID‐19), is mainly transmitted through droplets, aerosols, and direct contact.

We evaluated the utility of ORIGAMI to protect the face from aerosols and droplets. By wearing ORIGAMI on a doll's face, the protective ability of ORIGAMI was evaluated. A doll with ORIGAMI was dressed in a surgical mask, hairnet, and ORIGAMI. The other doll without ORIGAMI was dressed in a surgical mask and hairnet. To imitate the patient's cough or retching, experimentally, a balloon with a 7inch size containing 5×10-3 L of indigo carmine was inflated with air and ruptured with a needle device.

After 3 balloons were ruptured (Figure 2-A) , the stains of dolls' faces, surgical masks, hairnets were compared respectively. Some stains appeared in the surface of the ORIGAMI (Figure 2-B) . Some stains also appeared in the face, the surgical mask, and the hairnet of the doll without ORIGAMI (Figure 2-C) .

However, there was no stain in the face and the surgical mask of the doll with ORIGAMI (Figure 2-D) .
