Australian Meningococcal Surveillance Programme annual report, 2014. Commun Dis Intell Q Rep. 2016;40(2):E221-8 Authors: Lahra MM, Enriquez RP Abstract In 2014 there were 165 laboratory-confirmed cases of invasive meningococcal disease analysed by the Australian National Neisseria Network. This number was higher than the number reported in 2013, but was the second lowest reported since inception of the Australian Meningococcal Surveillance Programme in 1994. Probable and laboratory confirmed invasive meningococcal disease (IMD) are notifiable in Australia, and there were 170 IMD cases notified to the National Notifiable Diseases Surveillance System (NNDSS) in 2014. This was also higher than in 2013, but was the second lowest number of IMD cases reported to the NNDSS. The meningococcal serogroup was determined for 161/165 (98%) of laboratory confirmed IMD cases. Of these, 80.1% (129 cases) were serogroup B infections; 1.9% (3 cases) were serogroup C infections; 9.9% (16 cases) were serogroup W135; and 8.1% (13 cases) were serogroup Y. Primary and secondary disease peaks were observed in those aged 4 years or less, and in adolescents (15-19 years) respectively. Serogroup B cases predominated in all jurisdictions and age groups, except for those aged 65 years or over, where serogroups Y and W135 combined predominated. The overall proportion and number of IMD caused by serogroup B was higher than in 2013, but has decreased from previ...
