It's a tragic story but it isn't necessarily caused by dirty hospitals. Most of us carry MRSA in our bodies - often in our noses - so I imagine he could have become infected during birth, sadly. I'm shocked no-one picked up septicaemia, though.
Dirty hospitals are obviously a bad thing but MRSA is spread to patients by doctors, nurses and visitors not washing their hands. Have you seen how many visitors don't use the handscrub at the entrance to maternity wards? If you are ever in hospital, make sure any health professional touching you washes their hands first - and your visitors should do the same too.
