Analysis and reporting of meningococcal meningitis epidemic in north Gondar 2001-2002.

Severe epidemic meningococcal meningitis occurs in countries of the meningitis belt of Sub-Saharan Africa, including Ethiopia. Many epidemics occurred in this country in the past decade, the recent being in 2000 in Addis Ababa unusually during the wet and rainy season. The study was a cross-sectional design. Data were collected with prepared questionnaires and the line listing. CSF (Cerebro Spinal Fluid) culture and antibiotic sensitivities were done for a limited number of patients. The objective of the study was to assess the progress and management outcome of the epidemic. During the out breaks of epidemic meningitis in north Gondar zone of the Amhara regional state in 2001 and 2002 children and young adults were most affected. There were 384 cases and 26 deaths in 2001 and 1235 cases and 128 deaths, in 2002, making a total of 1619 cases and 154 deaths with a case fatality rate of 9.5%. The etiologic agent was sero-group A. The most affected age group was 15-30 years. About 80% of the cases were in the age 30 years and below. Surveillance, epidemic preparedness, interventions and response were found to be inadequate. Selective vaccination was not effective in handling the epidemic. Efficient surveillance, local processing and use of data, regional laboratory support, multisectoral approach and mass vaccination were recommended to appropriately and timely handle such epidemics.
