New UV lamp kills germs like MRSA
I was delighted to see a physicist come up with a far-UV light that kills bacteria with much more effectiveness that regular UV lights. Infections in hospitals kill millions every year, so this device is a welcome addition. Hospitals that just enforce basic hand-washing and room hygiene cut those rates in half, and this device will be a good weapon the arsenal to wipe out hospital borne staph also called MRSA (methicillin-resistant Staphylococcus aureus) completely.
When my mom was dying, one of the things that made the experience even more painful laws that she caught MRSA in the hospital. Once you have MRSA, you have to be in isolation, everyone wears masks in the room, and physical contact with you is severely limited. When I was leaving the hospital one night I notice a nurse that pushed the elevator button with the edge of her ID badge, a smart way to keep the germs off your fingers. See the Scrubs episode about infection (YouTube). The worse thing about MRSA is that my mom had to stay in isolation when I transferred her to a nursing home, until we could prove it was non-colonizing, and then we could take our masks off and mom could leave the room.
