Employees are in receipt of money from the coroners office and courts.
Quite often the money has blood stains or other fluid stains. There is no risk of contracting HIV from cash. Hepatitis B and C are more hardy and can be reactivated as long as a week or two later with moisture. However, to cause infection, they would have to come in contact with an opening into the money-handler's bloodstream. To reduce risk, I suggest that you advise employees to cover all cuts with bandaids.
