title: [Increased incidence of invasive meningococcal disease caused by C:2a:P1.2 meningococci in certain regions of the Czech Republic].
abstract: In the first half of 1993 an increased incidence of invasive meningococcal disease was recorded in the Czech Republic. In the CR a total of 59 cases were revealed, incl. 10 fatal ones. This high lethality (16.9%) is markedly higher than that from 036 recorded in this country during previous years. The highest incidence and death rate was recorded in the North Moravian region and in the age group from 15-19 years. Based on active surveillance of the invasive meningococcal disease by epidemiologists, microbiologists and infectiologists of the entire Czech Republic, it may be concluded that the sulphonamide sensitive strain Neisseria meningitidis C:2a:P1.2 caused in the North Moravian region a local epidemic of invasive meningococcal disease in the army and civilian population. In other regions of the CR the epidemiological situation in the first half of 1993 did not differ from the previous period: sporadic incidence of meningococcal disease, prevalence of the serological group B, highest incidence in the youngest age groups. The meningococcus C:2a:P1.2 was not detected in the CR before 1993. This uncommon epidemiological situation was resolved by immunization, aimed from the antigenic aspect and with regard to age and locality.
