The Meningitis Centre is urging all people to be on alert for the signs and symptoms of the potential deadly disease.
There already have been 14 cases of meningococcal disease in WA so far this year, including one death. At the same time last year there had been 9 cases notified, with no deaths.
Chair of the Meningitis Centre Bruce Langoulant said the incidence of the disease is highest in winter and spring.
"While the number of cases of meningitis has dropped dramatically since the introduction of new vaccines, there is no room for complacency," Mr Langoulant warned.
"Not all strains of the disease are covered by current vaccines and people need to be vigilant as every second counts."
The disease is most common in young children aged 0-4 years (around 45% of cases) and older teenagers and young adults aged 15-24 years (around 28% of cases).
Mr Langoulant issued the warning at the release of a new book to raise awareness of meningitis.
"Meningitis: A tragedy by instalments" was officially launched by Professor Fiona Stanley. It tells the stories of three families and their doctors who have been affected by the disease.
The book is available for purchase from the Meningitis Centre on 1800 250 223 or at www.meningitis.com.au
