Laboratory enhanced surveillance for meningococcal disease in Victoria

Abstract

Objective: To describe the epidemiological and microbiological characteristics and notification patterns of invasive meningococcal disease (IMD) in Victoria between 1990 and 1999. Methods: Cases of IMD occurring between 1990 and 1995 identified in any of three databases were combined, matching where possible. Statistical modelling provided estimates of cases missing from all datasets. Notification sources for 1999 and 2000 cases were identified. Cases identified from notification and laboratory results provided the data to describe IMD epidemiology between 1990 and 1999. Results: Between 1990 and 1995, 479 cases of IMD were identified. Three individual datasets each identified between 62 and..
