ABSTRACT

Introduction: Community-acquired bacterial meningitis is still today a serious challenge to global public health.
Objective: Identify the morbidity due to bacterial meningitis in Cuba and estimate the potential cases that might occur among those in which the causative bacterium is not identified, so as to ensure a more adequate and accurate assessment of this health problem.
Methods: An observational study was conducted based on data from the National Program for Surveillance of Bacterial Neurological Syndromes (1998-2014). Account was taken of the fact that the annual proportion of reported cases with an identified causative agent should be the same as the proportion of unidentified cases. A potential case was defined as a case deducted from those in which the bacterium is not identified, as in the assumption above, according to an equation developed by the authors based on the methodology recommended by the Pan American Health Organization for redistribution of signs and symptoms poorly defined in the International Classification of Diseases. Incidence was estimated for 105 inhabitants, based on the Cuban population.
Results: 6 668 cases were reported of community acquired bacterial meningitis (3.5/105 inhabitants) and the bacterial agent was identified in 2 967 (44.5%). Pneumococcus was isolated in 1 650 patients (0.9/105 inhabitants), meningococcus in 477 Pneumococcus caused 1 650 (0.9/105 inhabitants), meningococcus in 477 (0.2/105 inhabitants), Haemophilus influenzae in 339 (0.2/105 inhabitants) and other bacteria in 501 (0.3/105 inhabitants). The following estimates were made: 2 127 potential cases of pneumococcal meningitis, 605 meningococcal meningitis, 666 by H. influenzae and 641 by other bacteria. Estimated annual incidence (reported cases + potential cases) considerably exceeded the incidence notified.
Conclusions: Estimates make it possible to infer that morbidity due to these bacteria in Cuba may be higher than the values reported.
