For bus transit operators, potential sources of exposure include having close contact with a bus passenger with COVID-19, by contacting surfaces touched or handled by a person with COVID-19, or by touching your mouth, nose, or eyes.

• Limit close contact with others by maintaining a distance of at least 6 feet, when possible.
• Consider asking bus passengers to enter and exit the bus through rear entry doors.
• Request passengers avoid standing or sitting within 6 feet of the bus driver.
• Avoid touching surfaces often touched by bus passengers.
• Use gloves if required to touch surfaces contaminated by body fluids.
• Practice routine cleaning and disinfection of frequently touched surfaces, including surfaces in the driver cockpit commonly touched by the operator.
• Proper hand hygiene is an important infection control measure. Wash your hands regularly with soap and water for at least 20 seconds. If soap and water are not readily available, use an alcohol-based hand sanitizer containing at least 60% alcohol.
• Key times to clean hands in general include:
  • Before, during, and after preparing food
