A young South Australian has died after contracting meningococcal disease, marking the state’s first recorded death from the serious bacterial infection this year.
The Adelaide resident had been receiving life support after being diagnosed with invasive meningococcal disease, identified as serogroup B bacteria, in late October.
SA Health had identified multiple close contacts following the diagnosis, with seven people offered antibiotics to help prevent further transmission.

The death comes amid a sharp increase in meningococcal disease cases across South Australia.
There have been 22 cases recorded in the state so far this year, compared with 13 at the same time in 2025.

Of the 22 cases recorded in 2026, 20 have been linked to serogroup B, while one was identified as serogroup Y and another was non-serogroupable.
Until now, no meningococcal-related deaths had been recorded in South Australia this year.
Health authorities warn meningococcal disease can progress rapidly and become life-threatening within hours if not treated quickly.

Early symptoms can include fever, headache, vomiting, neck stiffness and sensitivity to light.
A distinctive rash may also develop, appearing as small red or purple spots that can rapidly spread and resemble bruising.
In infants and young children, warning signs can include irritability, drowsiness, refusal to eat, leg pain, cold hands and feet, a high-pitched cry and pale or blotchy skin.

Health Minister Blair Boyer recently urged South Australians to ensure they were protected against the disease through vaccination.
“We need to just remember that this can be fatal,” he said.
“I think sometimes there can be a tendency for us to get a bit blasé about things like this because we think they might be a problem of the past.”
While vaccination provides protection against several strains of meningococcal disease, health authorities warn it does not prevent all infections and people should remain alert for symptoms even if they have been vaccinated.
SA Health is urging anyone who develops symptoms consistent with meningococcal disease to seek urgent medical attention immediately.
