AIM: The meningitis it´s a common cause of mortality or several illness. The prognostic factor are described before and have a god correlation with mortality. MATERIAL AND METHODS: We review the files between June 2007 and May 2012, with diagnosis of Meningitis. The diagnosis was made by clinical suspicious and confirmed by Lumbar Puncture. Patients were included in two groups, with and without Culture positive. We analyzed Age, values from Cerebrospinal fluid, days before to start treatment. RESULTS: We include 119 patients, the mean age was 1.3 years and the range was 3 months to 12 years. The incidence of Bacterial meningitis was 30%, and the germ most frequent found was S. Pneumoniae. The global mortality was 28%, but the fatality rate of bacterial meningitis was the 52%. The mean age of patient deceased was 8 months. The most important values of cerebrospinal fluid was, a cellularity over 10,000 cells and hypoglycorrhachia <20mg/dl. That was most constant values of bad prognosis in patients deceased. The combination was found in 65% of them. The delay over 4 days in the treatment increase the risk of mortality 6 times. DISCUSSION: We found the same rate of bacterial meningitis described in other population, but we found a higher fatality rate of bacterial meningitis 52%, and the most frequent germ found was S. Pneumoniae. The most important factor of prognosis was: Age under 1 year, higher cellularity >10,000 cells, hypoglychorrhachia under 20 mg/dl and the delay in start the treatment over 4 days.
