Background: Meningitis is an inflammation of the meninges, and is defined by an abnormal number of white cells in the cerebrospinal fluid. Approximately1.2 million cases of bacterial meningitis occur annually worldwide. In young children, the most frequent causes include Neisseria eningitide(NM)Streptococcus pneumoniae (SP) and Haemophilus influenzae type b(Hib).More than 50% of Neonatal meningitis is caused by Streptococcus agalactiae. Sub-Saharan Africa (“meningitis belt”) has the greatest disease burdens of Hib,SP and NM infections. Hib and SP infections account for approximately 500,000 deaths per year in the region in 2001. NM is additionally responsible for recurring epidemics. This study highlights pattern of bacterial meningitis and complications in children at the University of Port- Harcourt Teaching Hospital (UPTH), in Southern Nigeria. Method: This is a 4 year prospective study of children with meningitis at neurology unit of UPTH between June 1st 2009 and May, 31st 2013. Results: Out of 10,094 patients seen in the department, 874 of them had meningitis, a prevalence of 8.66%. Male (568) and female (306), age range between 3 months and16 years. The bacterial yield was streptococcus pneumonia in    103(11.78%). They were all followed-up for at least one year to assess the outcomes. 94 cases (15.1%) with deficits -58 males and 36 females. The common complications are cerebral abscess 13 (13.83%), recurrent seizure 28(29.8%), motor developmental delay in 20%. Others were cortical blindness, speech deficits and behavioral impairment .Conclusion: It is important to prevent the disease by vaccination and sentinel surveillance.
