A Southern Area Health Service spokesperson said it was the fifth case of meningococcal disease in southern NSW this year. There was no association between the cases.
Winter is usually the time when sporadic cases of meningococcal disease occur.
Young children and adolescents are most at risk of developing the serious but rare infectious disease. SAHS Public Health director Julianne Quaine said the bacteria that caused meningococcal disease were passed on by saliva through kissing or sharing food, drinks and cigarettes.
