Question?

Should I have a plexi glass screen or some sort of cover for my desk at work? I take over 50 employees temperatures during one shift i work 5 days a week and I'm a receptionist. I work at a nursing home and I'm 28 weeks currently. There is only one exit allowed for people to go in and out of at the time being and only employees are allowed in which is a good thing. All of these people still go home after their shift and to the store and come back the next day. Cashiers in the stores I go all have them some sort of screen. I have asked someone in charge about getting me one. I just don't like people leaning and putting there hands all over my desk. I've already had multiple people even try to reach to help themselves to my phone, try to take their own temperature with the thermometer I was given to take temperatures with. I just hope they give me something.
