Risk of MRSA ?

My Mother in law is in hospital following a fall and has been diagnosed with MRSA following blood tests , she is 89 years old and not well at all , coughing and being sick . Thing is , my husband is wondering about the wisdom of visiting, he wants to see her and so do I , she is 6 hours car drive from us so it would mean staying overnight . Husband is now worried about possible effects of MRSA on me as a diabetic and that even if he went alone, there is a slight possibility of bringing the infection back here to me, is this worrying over nothing or is MRSA a big threat to diabetics ?

Thanks Sid , we`ve just been told that it is respitory MRSA with a severe lung infection and that , as she is coughing a lot, it can be airborne spread, puts a bit of a new light on it now, means masks and gowns etc . as she is in isolation x
