Two meningococcal cases put NSW Central Coast on high alert for symptoms

People on the New South Wales Central Coast have been told to be on alert for symptoms of meningococcal after two cases of the disease were recorded in the region since the start of December.

District director of public health Dr Kathryn Taylor called on residents to be on the lookout for signs of the illness, saying early intervention can be lifesaving.

"Meningococcal disease symptoms can appear suddenly and become very serious very quickly," Taylor said.

Meningococcal disease can be fatal within hours if left untreated.

Children under five and 15 to 25-year-olds are at the greatest risk of contracting the disease.

Indicators of serious illness include fever, a fast heart rate, cold hands and feet or a mottled look to the skin, difficulty waking or increased lethargy or confusion.

Symptoms of the disease include:

• Severe, unexplained limb pain
• Difficulty waking up
• High-pitched crying in babies
• Severe headache
• Upset by bright lights
• Stiff neck
• Red-purple rash which doesn't disappear when pressed with a glass

"While it is a well-known symptom of meningococcal disease, the rash does not always occur, or may present late in the illness," Taylor said.

"If symptoms rapidly worsen, or if your child is very unwell, call Triple Zero (000) or go straight to your nearest emergency department."
