rats carry a disease called weils disease, it can be very nasty if left untreated, so go see your doc as soon as possible. also this is a serious health and safety issue, so i would report it to your local health authority, even if you have to do it anonimously.

Yes, this could be some type of bacteria that you have picked up in your system from the droppings. Rats are very dirty rodents. Why doesn't your job do something
about this problem. How are the droppings getting on your desk? Why don't you report matter to your local health department. This can be done anonymously.
