Since a number of pianos I/we encounter have/had mice in them, I
wanted to
find out how long the virus was active and or infectious.  Here is the
reply
received from the CDC.

Paul:

The length of time hantaviruses can remain infectious in the
environment
is highly variable and depends on environmental conditions such as
temperature, humidity, whether the virus is indoors or outdoors
exposed
to the sun, and even the rodent's diet (which would affect the
chemistry
of its urine).  Viability for two to three days has been shown at
normal
room temperature.  Exposure to sunlight will decrease the time of
viability.  Freezing temperatures will actually increase the time that
the virus remains viable, especially if not exposed to sunlight.

One important practical conclusion from these data is the following:
since the survival of infectious virus is measured in terms of hours
or
days, only active infestations of infected rodents result in the
conditions which are likely to lead to human hantavirus infection.

How long does the hantavirus survive in the feces and urine of mice
when
the
mice no longer use the affected space?  Does the virus die when it
loses
its
host?  Does the risk of being infected decrease over time?
