"I also have a hunch that if ALL the case history of MRSA was correlated
there is some lifestyle or personal hygene issues. "
MRSA does seem to prosper anyplace where people are in close quarters
for prolonged periods of times. I read that the Los Angeles jail was
an outbreak site.
And I can't remember his name but one of the players on The Washington
Redskins also got MRSA and was at least out-of-commission for at
least a year.

"The newspaper headline, which states that tea tree oil can 'wipe out' the hospital superbug did not reflect either the newspaper or research articles, both of which reported eradication rates of just 41% for tea tree preparations."
The above passage is from the link that you gave me.
MRSA is a serious bacterial problem, and 41% effectiveness isn't going to do much to keep from spreading.
MRSA isolation is not practical as a large percentage of people have it on their skin at any time. Each person that enters the hospital presents another potential exposure. This is why hospitals are so concerned.
MRSA infections are more prevalent in hospitals because people there are sick, which can compromise the immune system, or they have had injuries or surgery, which give the bacteria a route into the body.
As for your theory about hygeine or lifestyle, I disagree. They are finding MRSA in many places that you would not expect it. Locker rooms and fitness clubs are breeding grounds. Schools and playground equipment too. It is far more common than you seem to think. You might even have it yourself.
I use tea tree oil for many things. It is a great cleaner. I also add it to shampoo. And If you don't have time to give your dog a bath, just add a few drops to a spray bottle with water and spray it on the dogs coat. It works well on cuts and skinned knees just don't use it full strength on your face. I found diluting it is better for my daughter's scrapes. Its great stuff.
I agree with you.Once you have had it,a recurrence is very likely to happen again.I know nurses who have gotten it more than once.I hope you are alright now.
My oldest daughter was bite by a few spiders. She got meningitis and then MRSA. She has had to have these strange lumps removed from her legs since then. Doctors have told her they are MRSA related.
I went to the hospital to see my mother who had MRSA. They had taken the notice off her door to suit up so I didn't. When the nurse saw my sister and I visiting without being suited up she threw us out. She told us to go home , take off our clothes by the washer and wash them ASAP. We then took hot showers. However we folded our coats over the rail near my parrot's cage. A few hours later my parrot fell to the bottom of the cage and died. I think it was from the coats but never proved it. We never came down with the MRSA. However my mom never got rid of it and had more problems until she died. Nursing homes are filled with MRSA and I won't let my daughter bring my grandson there during winter months. At least we can visit outside when the weather is good. MRSA is some nasty stuff to deal with.

-------------------------------------------------------------------------------- The susceptibility of Staphylococcus aureus [meticillin-resistant (MRSA) and meticillin-sensitive (MSSA)] and coagulase-negative staphylococci (CoNS), which respectively form part of the transient and commensal skin flora, to tea-tree oil (TTO) was compared using broth microdilution and quantitative in vitro timekill test methods. MRSA and MSSA isolates were significantly less susceptible than CoNS isolates, as measured by both MIC and minimum bactericidal concentration. A significant decrease in the mean viable count of all isolates in comparison with the control was seen at each time interval in timekill assays. However, the only significant difference in the overall mean log10 reduction in viable count between the groups of isolates was between CoNS and MSSA at 3 h, with CoNS isolates demonstrating a significantly lower mean reduction. To provide a better simulation of in vivo conditions on the skin, where bacteria are reported to grow as microcolonies encased in glycocalyx, the bactericidal activity of TTO against isolates grown as biofilms was also compared. Biofilms formed by MSSA and MRSA isolates were completely eradicated following exposure to 5 % TTO for 1 h. In contrast, of the biofilms formed by the nine CoNS isolates tested, only five were completely killed, although a reduction in viable count was apparent for the other four isolates. These results suggest that TTO exerts a greater bactericidal activity against biofilm-grown MRSA and MSSA isolates than against some biofilm-grown CoNS isolates. --------------------------------------------------------------------------------

Scroll down to results in the second paper and notice the rapid killing of all mrsa isolates within 3.5 hours. This is huge. Normally, a loading dose of vancomycin would require an entire life cycle of the bug to kill it.
Yes, Tea tree oil may only have an eradication rate of 41%-- but thats not the poing. Vancomycin has an eradication rate of upwards of 83%, but MRSA strains have developed resistance to vancomycin. A prokaryotic cell does not (as far as the literature is concerned) have the ability to generate a resistance to tea tree oil, except for its ability to generate pumps to pump the compounds out of the cell (which hasn't been shown).
In addition, if we're talking mrsa occurence in general, the majority of those infected and/or colonized present with dermatitis (a skin infection). Because tea tree oil can be applied topically, it is very promising to reduce this occurence, and also transmission from colonized hands of healthcare workers. To understand why a colonization redluction of 41% is so significant, you would have to understand the concept of "bacterial load" and environment, which is too complicated to get into here.
If you are a medic, I would highly recommend you carry tea tree oil hand sanitizer or lotion-- it will decrease the risk of you getting mrsa (not by 41%, but by much more than that because of the processes I mentioned above).
Oh, and as far as the hygeine point goes, I certainly believe this has truth-- mrsa would not exist if people weren't so careless about following antibiotic recommendations to the letter from their docs.
"The research article is a very poorly reported trial that provides limited evidence
Even the article didn't conclude what you say it does.
And your gibe about generating business for hospitals is so off the wall and so insulting, not only to medical care workers, but to the people who read the comment, that you should be ashamed.
I don't know!
No clue.
I do believe that antibiotics in any form are OVER used.

Staph is very dangerous and people don't realize it - that is most people.
