You should wear a disposable medical mask properly on your way to work and try not to take public transportation. It is recommended to walk, ride or take a private car or shuttle bus to work. If you must take public transportation, be sure to wear a mask throughout the journey and try to avoid touching objects on board with your hands. After taking a bus or subway on your way to work, it is recommended to wash your hands with soap or hand sanitizer in a timely manner, and if you are not in a position to do so, you can carry hand sanitizer with you to clean your hands and not to touch your mouth, eyes, nose and other parts with your hands during the ride. You can also wear gloves to avoid direct contact with handrails and other areas of high risk of infection.
