A 19-year-old woman has become the second person to die from meningococcal disease on the NSW Central Coast in a month.
Health authorities on Monday confirmed Mischelle Rhodes died from the disease at Gosford Hospital last week but the strain has not been confirmed.
"Our thoughts are with the family of this young woman at this tragic time," Central Coast Local Health District's Peter Lewis said in a statement.
It follows the death of a 38-year-old Central Coast woman from the W strain of meningococcal disease in early August.
However, authorities say there is "no known link" between the two cases.
Dr Lewis said mengingococcal disease is very uncommon in NSW.
A total of 41 cases have been reported in NSW this year, according to NSW Health.
Nearly half (19) were the B strain, while 11 were the W strain.
"If anyone in the community develops any symptoms of meningococcal disease, it's important that they seek medical advice immediately," Dr Lewis said.
Symptoms can include fever, headache, neck stiffness, joint pain, a rash, dislike of bright lights, nausea and vomiting.
Meningococcal bacteria does not easily spread between people, nor do they survive well outside the human body.
