Okay, I can offer some advice to you on this problem. You have always posted to my threads with great advice so now it's my turn.
I also culture PA and MRSA and have for the past 5 years now. I originally contracted it while working in the hospital with CANCER patients. After contracting it, I lost my job because I was considered a threat, and a JACO report had to be filed with the hospital. It was a HUGE deal.
Five years ago, MRSA was a HUGE deal! I wouldn't say it was considered a 'death sentence', but there was nothing good to say about it. However, today it is considered a 'moderate bug'.
Now to your question...My neighbor was just diagnosed with pancreatic cancer this past December. She is such a sweetheart. I felt so bad...She was the little, old lady at my door with brownies the day Jake and I moved in this past November. She is so sweet...
I immediately wanted to reach out and help her whatever way I could. For one, she is so sweet. For two, I worked in cancer and knew that her survival rate after one year of diagnosis was only 10%! I knew she wouldn't have too long...For three, I don't work or anything so I had plenty enough time.
Before I went to help her, I had an appointment with my CF doctor. I brought the whole issue up to him and he said that it was 'okay' for me to help her. He had no problem with it at all. He told me that I could help whenever I wanted but to avoid her if either I or her were sick or in the hospital. So I have been helping her for a couple months now, and I haven't had any problems. She is now on Hospics so it's only a matter of time. I'm so thankful that I had the chance to help her. It also helped me find closure because I lost my job so suddenly.
I would still ask your CF doctor, but I don't think there is a problem. I believe the only concern is the contracting of MRSA. However, you and I already have it so I really don't think there is an issue. Just be careful if she gets sick.
Edited to Add: As far as her safety is concerned, ask your doctor. Breast cancer is usually cureable so maybe her possibly contracting MRSA is an issue. In the case of my neighbor, the chance of contracting MRSA didn't really matter. I hate to admit it, but her cancer is what is doing her in. I still don't think there should be an issue, though. <img src="i/expressions/heart.gif" border="0">
Another interesting tidbit...We had a connection from the very beginning. WE BOUGHT HER DAUGHTER'S HOUSE!!!
