Designed for use in healthcare settings, there are  mouses  completely sealed from fluid ingress, while being compatible with any hospital cleaning agent. They are ideal for use in patient rooms, OR's, nursing stations, or anywhere cross-contamination is a concern. They  feature a comfortable, ergonomic design, as well as smooth-surface buttons that are easily wiped clean.

As well, keyboards should all be tactile. Their smooth surface not allowing bacteria to hide in any crack.
Investing in these more sophisticated tools pays off if one considers that it will help reduce the high costs associated to infections.
