Dear Desi,
MRSA is a Staphlococcus Infection that is resistant to most antibiotics. It is a huge problem for hospitals and health care institutes as it can enter wounds after surgery and cause infections but because it is not sensitive to most antibiotics it is harder to treat and the complications come in the form of long term hospitilisation and the possibility of septicaemia.
It is particulalry dangerous, as is any infection, for the elderly, people with chronic illnesses and babies.
Most of us are well able to fight off these infections with our immune systems.
To have an outbreak in the school would indicate that an infected child has come to school, not washed his hands and therefore passed it on. It does not mean the school has been remiss in it's duty of care.
Staph is everywhere, many of us will be carrying MRSA as normal body flora but we do not get sick from it.
As Jose said the ONLY way to stop this spread is to actively encourage your children to be vigilant about washing hands after toilet after playtime and before eating.
Perhaps you could provide your little girl with some antibacterial wipes in her school bag?
Please do not panic Desi

Most people do not get sick from contact unless there is a wound and even then handwashing will help to eliminate that risk.
Take care and love
Tayla
