Health officials recently reported the death of a 22-month-old girl from Adelaide who has just died due to meningococcal disease.

This was the first fatality case associated with meningococcal in South Australia this year, according to health authorities.

Paddy Philips, chief medical officer of SA Health informed that meningococcal was a severely dangerous condition with a mortality rate of 10 to 15 per cent.

Prof Philipidens said of the 30 contacts identified by the SA Health authorities, 22 of them - family members and health care officers - have been given medical assistance and antibiotics.

The state coroner is currently looking into the girl's death.

In South Australia, her case was the tenth reported meningococcal-related death this year compared to a total of eight cases observed last year at similar period of time.
