Health authorities in South Australia have issued an urgent warning following the hospitalization of two women diagnosed with a highly infectious disease. A 29-year-old and a 55-year-old, both from the same household in inner-city Adelaide, have been confirmed as cases of invasive meningococcal disease, specifically serotype B.
Meningococcal disease is caused by bacteria that are typically carried in the nose and throat. Serotype B accounts for a majority of cases globally. As a precaution, South Australian Health (SA Health) has identified that multiple people came into contact with the affected individuals, leading to nine others being advised to take antibiotics to mitigate the risk of further transmission.
As of this year, South Australia has recorded a total of 12 meningococcal cases, contributing to an overall state total of 30 cases in 2024.
Symptoms and Precautions
SA Health has emphasized the importance of recognizing the symptoms associated with meningococcal disease. These can include severe headache, fever, vomiting, neck stiffness, and sensitivity to light. A distinctive skin rash may develop, characterized by small red or purple spots that can spread and resemble fresh bruises.
In young children, signs may present differently. They might appear fretful, difficult to wake, and may refuse to eat. Additional symptoms in this age group may include leg pain, cold extremities, and a high-pitched or moaning cry.
Health officials are urging all Australians to stay up-to-date with their meningococcal vaccinations to prevent further spread of the disease. Vaccination remains a critical tool in combating this serious infection, and public health messages stress that timely intervention can save lives.
As the situation develops, authorities continue to monitor the health of the affected individuals and provide updates to the community.
