Expansion of Neisseria meningitidis Serogroup C Clonal Complex 10217 during Meningitis Outbreak, Burkina Faso, 2019.

During January 28-May 5, 2019, a meningitis outbreak caused by Neisseria meningitidis serogroup C (NmC) occurred in Burkina Faso. Demographic and laboratory data for meningitis cases were collected through national case-based surveillance. Cerebrospinal fluid was collected and tested by culture and real-time PCR. Among 301 suspected cases reported in 6 districts, N. meningitidis was the primary pathogen detected; 103 cases were serogroup C and 13 were serogroup X. Whole-genome sequencing revealed that 18 cerebrospinal fluid specimens tested positive for NmC sequence type (ST) 10217 within clonal complex 10217, an ST responsible for large epidemics in Niger and Nigeria. Expansion of NmC ST10217 into Burkina Faso, continued NmC outbreaks in the meningitis belt of Africa since 2019, and ongoing circulation of N. meningitidis serogroup X in the region underscore the urgent need to use multivalent conjugate vaccines in regional mass vaccination campaigns to reduce further spread of those serogroups.

Cost of pediatric hospitalizations in Burkina Faso: A cross-sectional study of children aged <5 years enrolled through an acute gastroenteritis surveillance program.

INTRODUCTION: Diarrheal illness is a leading cause of hospitalizations among children <5 years. We estimated the costs of inpatient care for rotavirus and all-cause acute gastroenteritis (AGE) in two Burkina Faso hospitals. METHODS: We conducted a cross-sectional study among children <5 years from December 2017 to June 2018 in one urban and one rural pediatric hospital. Costs were ascertained through caregiver interview and chart abstraction. Direct medical, non-medical, and indirect costs per child incurred are reported. Costs were stratified by rotavirus results. RESULTS: 211 children <5 years were included. AGE hospitalizations cost 161USD (IQR 117-239); 180USD (IQR 121-242) at the urban and 154USD (IQR 116-235) at the rural site. Direct medical costs were higher in the urban compared to the rural site (140USD (IQR 102-182) vs. 90USD (IQR 71-108), respectively). Direct non-medical costs were higher at the rural versus urban site (15USD (IQR 10, 15) vs. 11USD (IQR 5-20), respectively). Indirect costs were higher at the rural versus urban site (35USD (IQR 8-91) vs. 0USD (IQR 0-26), respectively). Rotavirus hospitalizations incurred less direct medical costs as compared to non-rotavirus hospitalizations at the rural site (79USD (IQR 64-103) vs. 95USD (IQR 80-118)). No other differences by rotavirus testing status were observed. The total median cost of a hospitalization incurred by households was 24USD (IQR 12-49) compared to 75USD for government (IQR 59-97). Direct medical costs for households were higher in the urban site (median 49USD (IQR 31-81) versus rural (median 14USD (IQR 8-25)). Households in the lowest wealth quintiles at the urban site expended 149% of their monthly income on the child's hospitalization, compared to 96% at the rural site. CONCLUSIONS: AGE hospitalization costs differed between the urban and rural hospitals and were most burdensome to the lowest income households. Rotavirus positivity was not associated with greater household costs.

Costs and impact of meningitis epidemics for the public health system in Burkina Faso.

BACKGROUND: Epidemic meningococcal meningitis remains a serious health threat in the African meningitis belt. New meningococcal conjugate vaccines are relatively costly and their efficiency will depend on cost savings realized from no longer having to respond to epidemics. METHODS: We evaluated the cost and impacts to the public health system of the 2007 epidemic bacterial meningitis season in Burkina Faso through a survey at the different level of the health system. A micro-economic approach was used to evaluate direct medical and non medical costs for both the public health system and households, as well as indirect costs for households. RESULTS: The total national cost was 9.4 million US$ (0.69 US$ per capita). Health system costs were 7.1 million US$ (1.97% of annual national health spending), with 85.6% for reactive vaccination campaigns. The remaining 2.3 million US$ was borne by households of meningitis cases. The mean cost per person vaccinated was 1.45 US$; the mean cost of case management per meningitis case was 116.3 US$ when including household costs and 26.4 US$ when including only health sector costs. Meningitis epidemics disrupted all health services from national to operational levels with the main contributor being a large increase in medical consultations. CONCLUSIONS: Preventive meningococcal conjugate vaccines should contribute to more efficient use of funds dedicated to meningitis epidemics and limit the disruption of routine health services.

Costs for households and community perception of meningitis epidemics in burkina faso.

Bacterial meningitis in the African meningitis belt remains 1 of the most serious threats to health. The perceptions regarding meningitis in local populations and the cost of illness for households are not well described. We conducted an anthropologic and economic study in Burkina Faso, in the heart of the meningitis belt. Respondents reported combining traditional and modern beliefs regarding disease etiology, which in turn influenced therapeutic care-seeking behavior. Households spent US $90 per meningitis case, or 34% of the annual gross domestic product per capita, and up to US $154 more when meningitis sequelae occurred. Much of this cost was attributable to direct medical expenses, which in theory are paid by the government. Preventive immunization against meningitis will overcome limitations imposed by traditional beliefs and contribute to poverty reduction goals.
