D.O.
Does your niece have MRSA as a result of a wound or is she just a carrier of MRSA? My mother-in-law had it when she was in the nursing home and she had a wound on her foot. She was treated and is now OK. I must have picked up the MRSA from spending time with her because when I had my twins in Jan 2007, I tested positive as a carrier. (The hospital I was at checks everyone as a routine.) They stuck a swab up my nose and it came back as MRSA. I was terrified, horrified, etc. I thought I was a leper (sp?) and had ruined my kids lives. For 5 days, my newborn twins and I had to put an antibiotic up our noses to treat it. We did the normal hygiene you do with newborns around -- disinfected, washed hands, etc. Eventually I forgot about it (took a LONG time). When I had my last baby in May 2008, I tested negative for MRSA. They say that 30%-40% of the general population walks around with it and there's nothing to worry about as long as it's not in a wound or in your blood stream. I know it sounds very scary, but I wouldn't get your daughter scared about playing with your niece. Talk to your pediatrician and they should be able to give you some information. GOOD LUCK!!
