Well, now, here's the ultimate in coddling to people's phobias.

If I were a cynic, I'd be looking for ties between this "new study" (they only come in two flavors, new and discredited) and the Copper Institute of America.

If hospitals were truly serious about preventing infection, they would provide attendants to open doors, turn water taps on and off, and flush our toilets for us.

It would be a much better article if it provided information as to why copper worked at reducing bacteria.

Worried about bacterial infections in hospitals from door handles, try kissing one's hand after touching the mezzout. Here in Israel research was undertaken in a hospital to determine if the mezzout were akin to a Petrie dish in that they were seldom if ever cleaned. As expected they were carriers of infectious bacteria/pathogens and kissing ones hand/fingers after touching the mezzout in hospitals is, not without risks.
A. Davey (Portland)
I don't know what a "mezzout" is and neither does Google.

Google came back with "Did you mean: mazout, mezzo, mezza,mezzat?" No, I did not.

A definition of the term for those of us who are not patients in Israeli hospitals would be appreciated.

We need copper flush handles.

I am a frequent visitor to large hospitals and have over the years developed a routine to avoid infections from physical contact. After making my last contact in the hospital - I visit the rest room to wash my hands and then using the paper tower, open the door with it and toss it away.

If I must open a pull door - I do it with the little finger of my left hand and the same with touching elevator buttons.

The last time time I got a cold in a hospital was when I shook the hand of the 8 year old daughter of a senior manager as it was the day to bring your kids to work.

I have missed 4 days school/work since kindergarten and am 75 YO.

Still working - avoid the bad bugs.

Yes, always use a paper towel to open a bathroom door. Or, if there are no paper towels and the door isn't already open, using a pinkie is the way to go. It's rare that you rub your eye or wipe a crumb from your mouth with your pinkie . . . .

water heaters were once made of copper and would last 25+ years. i wonder if this purified the water as it sat there overnight?
Old style Linoleum was used in hospitals and is a bacteriocide as well, made of mostly wood dough and
turpentine which out gassed and did the killing

I wonder if copper coins like pennies have less germs than nickels, dimes, and quarters?
Bill Sardi (San Dimas, California)
Bacterial count lower but will that translate into fewer infections? What needs to be done is build up immunity of hospitalized patients. How much longer will hospitals allow immune compromised patients to be admitted without vitamin C, D and zinc food fortification? The patient's skin is loaded with bacteria. It is a break in the natural defenses against germs that results in these deadly infections and overuse of antibiotics.
Justice Holmes (Charleston)
Another way is convincing hospitals that they should be kept clean and that doctors should wash their hands! When hospitals insist on hiring minimum wage workers with no training in why a hospital must be kept clean and then leave those workers with no supervision, to quote an administrator,
" infections simply are the risk of being in a hospital"!

Now some infections may happen not matter what but many of the infections now occurring are happening because hospitals no longer see the "benefit" to their bottom line of enforcing sanitation....this is so whether it comes to floors or the cleaning of surgical theaters or medical devices. The NYT did a very chilling exposing on just the issue a few years ago.

Does it follow from this article that the copper water pipes found in many homes are better than the plastic pipes often used which are less expensive and easier to install, especially in areas with high bacterial levels in the water?
Martha Shelley (Portland, OR)
This isn't news. I've known about this for years. The ancient Egyptians, Aztecs, and Mongolians knew about it. (see http://ebisupublications.com/copper-germs-ancient-egypt/ ) The problem these days is that using copper for faucet handles, door handles, light switches, etc. is a lot more expensive than using plastic. Medicare and other insurers will reimburse hospitals for treating a patient who contracts an infection, but won't reimburse for replacing the germ-laden equipment.
JPE (Maine)
Medicare is not there to provide capital support. That's simply not its mission. If we let Medicare fund copper faucets, before you knew it the American Hospital Association would have dozens of studies justifying copper roofs, copper computer keyboards, copper counters, copper phone directories...a never ending list all ostensibly to be paid for by federal dollars. We need to look elsewhere for capital funding for such items.
Hilda (<br/>)
The "news" is the study, not the antimicrobial properties of copper.
Martha Shelley (Portland, OR)
JPE, I understand that Medicare doesn't fund these things. What I was saying is that there is a significant financial disincentive to change the faucets, etc. I am hoping that some regulatory body will demand such changes take place within a given period (e.g., 3 years). Hospitals have to meet certain health standards as it is and this one can be added.
Tom Kline (Boat, The Caribbean)
They would still need to leave some rooms unchanged for people with copper allergies would they not?
ML (Ny)
This makes me think of copper IUDs. They are used for contraception, but is the mechanism of copper ions similar? How do copper ions affect bacteria and sperm, but not affect the cells in my uterus?

For those of us who suffer from bronchiectasis and/or are colonized with a rare type of non-tuberculous mycobacteria (NTM), copper pipes in homes and hospitals might do a lot to help prevent our condition. Vulnerable individuals with bronchiectasis (bronchial tubes that can't expel mucus and become ripe for infection with rare bacteria) may also be open to NTM, horrible rare mycobacteria that are found in our water supply, including in apartment buildings and in hospitals. I, myself, live with Lady Windermere Syndrome, a rare condition which the Times covered as such, where my particular frame and other physical characteristics, make me susceptible to these water-borne pathogens. There's a significant group of women (and men) in New York who live with this illness.
Maire Kelly (Rep of Ireland)
Copper had always been used in earlier times, we have it in our body also. I cook with copper pots all the time - and my drinking water runs through copper pipes, it will tarnish and perhaps that kills most bacteria. In Western Europe its got very expensive and thieves are stealing it from electric overhead poles, empty houses and yards.
A Goldstein (Portland)
The title of the article in AJIC refers to alloys containing copper. It's important for readers to know this.
Costantino Volpe (Wrentham Ma)
Basically, copper ions (and I think Silver also) are toxic to bacteria.There are systems out there that use silver anodes in filter systems to treat pool water so use of chlorine is minimal
Kyle W (Manhattan)
Copper and Silver are very chemically similar. They are vertical with respect to each other on the periodic table which makes them electronically similar!

So how soon till we get copper subway poles??

this is very helpfull

Copper is becoming a accepted form of metal for combating hospital pathogens. With patients leaving the hospitals and returning within days from contracting stapf infections, copper studies show that it has promising results in not allowing the harboring in general of these type of microbes. Conventional metals in hospitals use mostly stainless components and this is were the problem lies in these studies. Copper,in its purest form is microbial resistant and the copper industry is in the process of establishing FDA type specifications that designate these metals for hospital use. Bronze is copper mostly but contains other alloys such as zinc as alloying element and can degrade the effectiveness of the copper in a hospital setting

I believe that copper and copper/steel sinks stop C-Diff spores dead in its tracks. There's a ton of research regarding different types of sinks and their ability to either stop or reduce bacteria growth.
Susan (Eastern WA)
Either the title is misleading or the article incomplete. The copper in the article refers to "faucet handles, toilet flush levers, door handles, light switches and other commonly touched equipment," not sinks and faucets themselves. These are much smaller than a sink and therefore likely much less expensive to replace.
M. L. Chadwick (Portland, Maine)
OK, so what is it about copper that has this effect? I don't need a dissertation--just a clue...
a goldstein (pdx)
Certain metals are microbicidal.
Umm..excuse me (MA)
The effect is likely caused by the interaction between copper ions (which are charged) and microbial membranes. All cells, including cellular organisms, maintain a transmembrane electrical potential and contact with copper ions disrupts this potential. Resulting holes in the membrane can kill the organism by further exposing it's internal biochemical processes to the disruptive effects of copper ions which bind to internal proteins and halt cellular metabolism. Holes in the cell membranes may also be caused by direct oxidative damaged cause by copper ions interacting with cell membrane constituents in the presence of oxygen.
Lauren (PA)
Broadly speaking, copper ions are pretty reactive. They like to bind to or alter the structure of proteins, which are what bacteria and viruses use to live and grow.
A Goldstein (Portland)
Just to be clear, this article is not referring to bathroom fixtures made from pure copper but instead, copper-containing alloys like brass and bronze. Pure copper would likely be too reactive and would stain anything around it.
Margalo (Portland, OR &amp; Albuquerque, NM)
Pure copper, long known in India for its antibacterial properties, is required to get the results described.
Declan (Los Angeles)
It would be just the handles on faucets and toilets. The light switch even the hand dryer knob. Everything you may touch when you go to the bathroom. Even the soap dispenser. I am guessing.
Kim and Scott Genzer (Vermont)
Correct. The alloy used in this study was C706 - 90% copper and 10% nickel. It has lots of names like "white copper" or "Farmer's Copper". Brass is copper and zinc; bronze is copper and tin. I work with pure "L" grade copper to make bathroom fixtures like faucets in my shop. Pure copper does have its downsides like oxidation (like the greenish patina you see if left alone long enough) and strong electric conductivity, but it is cheaper than C706, easy to work with, and of course beautiful to look at.
