Good morning everyone. I have just spent the last hour and a half on a site called: Pubmed.gov. It is a great place to look up all things MAC or any other medical issue. I could spend DAYS on there! I learned that Japan has the highest incidence of MAC in the world. They are extremely cutting edge people so I was hoping that they might have answers for better treatment. I will keep digging. One thing I did read concerning Japan’s epidemic of MAC; is they are very concerned at the lack of attention to this disease in the research departments. We ALL should be concerned about this.
