Ooh, love that flowered/plaid/mosaic combo of the wallpaper/uphostery/flooring!
On the hantavirus: Yes, this is a deadly serious disease, and the virus can be contracted from rodent droppings or urine, BUT
the virus does not live that long after "leaving" the mouse, so if you can be sure there have been no mice in the trailer in the last few weeks or so, you are probably not facing serious exposure. Of course it's always good to handle such things carefully.
Here is an except from the US CDC (to which the BC health page refers people). The bold text is from the CDC page, and was not added by me:
: Anything that puts you in contact with fresh rodent urine, droppings, saliva or nesting materials
can place you at risk for infection.
: Hantaviruses have been shown to be viable in the environment for 2 to 3 days
at normal room temperature. The ultraviolet rays in sunlight kill hantaviruses.
: Rodent control
in and around the home remains the primary strategy for preventing hantavirus infection.
: Use a bleach solution or household disinfectant
to effectively deactivate hantaviruses when cleaning rodent infestations.

I wish I had known about the latency factor years ago. A good friend of mine used to work on old pianos, and they were often the home to mouse droppings. But... the mouse droppings were known to be old. We didn't know about the relatively short life of the virus and so we worried excessively at times when we needn't have since they weren't "fresh."
