A man is in a Hunter hospital with a confirmed case of meningococcal disease.
Hunter New England Health reports he's in a stable condition.
It's the eighth reported case of the disease in the Hunter this year.
While it is a rare and potentially life-threatening disease, in most cases early detection and treatment can result in a full recovery.
The first signs of meningococcal disease may include pain in the legs, cold hands and feet and abnormal skin colour. Later symptoms may include high fever, headache, neck stiffness, dislike of bright lights, nausea and vomiting, a rash of reddish-purple spots or bruises, and drowsiness.
