• Environmental service workers may be exposed to measles through contaminated surfaces.

Environmental services workers may have exposure to contaminated environments and surfaces that can transmit the measles virus.

Activities that can lead to environmental services worker exposure include:

• Working in environments where an infected person is or has been within the previous two hours.
• Cleaning or otherwise having contact with environmental surfaces contaminated with an infected person’s infectious body fluids (i.e., respiratory secretions, saliva). Cleaning tasks that involve using pressurized sprays of water or cleaning chemicals can create potentially infectious aerosols.
