I work in a retail environment. A customer that is 100% confirmed to have the disease, who is also on drugs, came into the store. I was within close proximity to the customer, handled and accepted money that the customer gave me. I used hand sanitizer immediately following the transaction, and shortly after washed my hands. Is it possible that somehow interacting with this individual, that I have contracted the virus? No visible blood was on the customer or myself. I am more worried that somehow the customer's saliva landed on me while I was within proximity. I am something of a hypochondriac...what do you think?
