1 Route of Transmission of COVID-19

The routes of transmission of COVID-19 are droplet transmission and contact transmission.

○ Droplet Transmission

Droplet transmission refers to cases of infection by breathing in the virus contained in the spray (droplets) from coughs or sneezes of an infected person.

○ Contact transmission

Contact transmission is infection caused by touching a contaminated surface with your hand and then touching your eyes, nose or mouth.

2 Disinfection at home or inside the public facilities

It is important to keep frequently touched places clean and hygienic. It is known that rubbing alcohol is effective for sanitizing the skin, including hands, and that sodium hypochlorite is an effective disinfectant for surfaces.

e.g.) If the product has a concentration of 6%, into a 2-liter PET bottle, pour

0.1% = approx. 33 mL (6-7 capfuls of a PET bottle)

0.05% = approx. 17 mL (3-4 capfuls of a PET bottle)

0.02% = approx. 6.7 mL (1-2 capfuls of a PET bottle)

(1 capful = approx. 5 mL).

• If using on metal surfaces, wait about ten minutes before wiping with a damp cloth.

• Do not spray with a spray bottle.

• Read the instructions printed on the product well before use.
