Seroepidemiology of invasive pneumococcal disease in Queensland, 1990 to 1997.
Serotypes responsible for 842 cases of invasive pneumococcal disease in Queensland between February 1990 and October 1997 were identified. Type 14 caused 37.5% of episodes in children aged 0-4 years and 19.2% of adult cases. Types 6A, 6B, 14, 18C, and 19F were significantly more frequent in young children while types 3, 4, 7F, 9V and 23F predominated in adults. The regional incidence of type 14 and 7F disease differed significantly in Southeast and Far North Queensland. Coverage for 87% of children aged less than 5 years in this study would be provided by a recently advocated polysaccharide-protein conjugate vaccine containing capsular antigens of types 4, 6B, 9V, 14, 18C, 19F and 23F. Similarly, more than 90% of adults would be covered by the currently available 23- valent polysaccaride vaccine.
