Upsurge in meningitis cases in Jirapa district, 2017, Upper West - Ghana

Abstract

Introduction: Meningitis is the inflammation of the meninges. In the first eight (8) epidemiological weeks of 2017, Jirapa District, Upper West Region, Ghana recorded 41 suspected cases with six deaths and this had exceeded the alert threshold of 5 suspected cases per 100,000 population per week. We therefore conducted an epidemiological investigation, assessed surveillance and epidemic response and helped implement control measures. Methods: We conducted a descriptive study in Jirapa District 21st to 25th March, 2017. We reviewed patient records from January to March with clinicians, response and surveillance assessment and searched for cases. The case definition was any person living in Jirapa District and reporting with or without fever of acute onset with neck stiffness, poor sucking (in infants), bulging fontanelles (in infants), altered consciousness, other signs of meningeal irritation/inflammation from 1st January to 25th March, 2017. Descriptive analysis was performed and expressed as frequencies and proportions with Microsoft Excel, 2016. Results: Sixty-one cases were recorded, of which 10 were confirmed with seven deaths (CFR=70%). Most were female 32 (53.33%) and majority, 21 (34.4%) below age 10 years. Streptococcus pneumoniae was the causative organism in all the 10 samples. Although the number of reported meningitis cases and the CFR were high, the epidemic threshold of 10 suspected cases per 100,000 population per week was not crossed. There was an active surveillance and effective rapid response team in the district conducted health education and contact tracing when the number of cases were increasing. Conclusion: Jirapa District saw an increase in the number of reported meningitis cases in 2017. An active surveillance system and effective rapid response team in the district prevented a potential outbreak. Communities were educated on risk factors, preventive measures to reduce spread and the need for early reporting.
