Hi,
First of all, it is bacterial infection not "viral" and MRSA, means methicillin-resistant staphyllococcus aureus. Recently, so many sub-categories has been described but it is useless for you to understand. What is important for you is it's treatment. As this organism is extremely resistant to most antibiotics (Penicillin and Cephalosporins), it causes lot of brain-exertion for even very experienced physicians because it's 100% treatment can not be predicted.
Your physician alrady doing what he or she can for it. However, ask him or her if he or she can prescribe you any thing to boost your "immune system". Sometimes, increasing the strength of "internal defense" may cause the relief from this tedious infection. Vancomycin, as your doctor did try, is one of few options. There are few new medicines which can be prescribed on "out-patient" basis.
As this infection poses lot of risk if hospitalized ( it mostly originates from hospitals, community health set ups and bacteria has become resistant already to most of medicine), that is why your physician not referring you to hospital because it can endanger your life.
There is another treatment known as "Phage treatment" offered by "Eliava Institute of Georgia". Contact them if they can help. OR
Ask your physician if he or she can prescribe "linezolid" or combination of Fusidic acid and Rifampicin, or combination of Rifampicin and Fluroquinolone, or Pristinamycin.
Do not get discourged rather look vigorously for its treatment and try your level best not to spread this to other persons who are in contact with you.
