Public policies promoting the informal economy: effects on incomes, employment and growth in Burkina Faso

Since the 1990s, Burkina Faso has intensified the implementation of supporting policies to enhance the access to capital and liquidity in the informal economy. This paper analyzes the effects of these policies on incomes, employment and economic growth by taking into account the interactions between the informal sector, the formal sector and the agricultural sector. For that purpose, policy shocks are simulated through the Partnership for Economic Policy Network’s static computable general equilibrium model which is adapted to the structure of a 2008-based social accounting matrix developed by the International Food Policy Research Institute. Our results highlight mixed effects including a paradoxical contraction of the informal sector, the formal sector and economic growth as well as an improvement of the informal households and the farmers’ incomes

Risk factors associated with HIV prevalence in pregnant women in Burkina Faso, from 2006 to 2014

Purpose of the study: To determine the socio-demographic factors influencing the dynamics of HIV prevalence among pregnant women in Burkina Faso.Material and methods: A total of 66,597 pregnant women from the 13 health regions of Burkina Faso were included in this study conducted between 2006 and 2014. Venous blood samples were collected and analyzed for the detection of HIV antibodies according to WHO / UNAIDS strategy II, using the mixed test Vironostika HIV Uniform II Plus O (Bio-Mérieux) and the test discriminating ImmunoCombII HIV-1 & 2 BiSpot (Orgenics). Samples with discordant results between the two tests, as well as those positive to HIV-2 or HIV-1 + 2, were retested with HIV BLOT 2.2 (MP Diagnostics). Sociodemographic data collected from the participants were correlated with their HIV status to determine key risk factors influencing HIV infection prevalence in Burkina Faso.Results: Sociodemographic data showed that the study population consisted mainly of married women (91.2%) at their first pregnancy (27.1%) with a large majority of them being housewives (86.2%) who did not attend any form of schooling (69.4%). About 88.4% had stayed longer than a year in the health region where they initially participated in the study and 55.8% were between 20 and 29 years of age. Overall HIV prevalence significantly dropped from 2.7 % in 2006 to 1.3% in 2014. However HIV seroprevalence in this study has varied significantly according to socio-demographic characteristics including marital status, parity, occupation, education, age group and the length of stay in the women's health community (p <0.0001). Factors sustaining HIV transmission included the status of being unmarried (OR=1.67 [1.42-1.97]), primigest (OR=1.64 [1.41-1.89]), having other occupations except being student (OR = 1.68 [1.20-2.33]), aged between 20-49 years (OR=3.14 [2.51-3.93]) and the duration of stay less than a year in their locality (OR=5.33 [4.61-10.16]) and these factors were identified as main risk factors associated with HIV prevalence.Conclusion: Burkina Faso remains among the countries with concentrated epidemics despite a significant reduction in the prevalence observed in this study. The inclusion of identified risk factors in the national HIV program could improve the quality of the response to the epidemic.Keywords: HIV-Pregnant Women-Risk Factors-Burkina Fas

Has the Gratuité policy reduced inequities in geographic access to antenatal care in Burkina Faso? Evidence from facility-based data from 2014 to 2022

BACKGROUND: Evidence shows that user fee exemption policies improve the use of maternal, newborn, and child health (MNCH) services. However, addressing the cost of care is only one barrier to accessing MNCH services. Poor geographic accessibility relating to distance is another. Our objective in this study was to assess the effect of a user fee exemption policy in Burkina Faso (Gratuité) on antenatal care (ANC) use, considering distance to health facilities. METHODS: We conducted a cross-sectional study with sub-analysis by intervention period to compare utilization of ANC services (outcome of interest) in pregnant women who used the service in the context of the Gratuité user fee exemption policy and those who did not, in Manga district, Burkina Faso. Dependent variables included were socio-demographic characteristics, obstetric history, and distance to the lower-level health facility (known as Centre de Santé et Promotion Sociale) in which care was sort. Univariate, bivariate, and multivariate analyses were performed across the entire population, within those who used ANC before the policy and after its inception. RESULTS: For women who used services before the Gratuité policy was introduced, those living 5-9 km were almost twice (OR = 1.94; 95% CI: 1.17-3.21) more likely to have their first ANC visit (ANC1) in the first trimester compared to those living 10 km from the nearest facility were almost twice (OR = 1.86; 95% CI: 1.14-3.05) and over twice (OR = 2.04; 95% CI: 1.20-3.48) more likely respectively to use ANC1 in the first trimester compared to those living within 5 km of the nearest health facility. Also, women living over 10 km from the nearest facility were 1.29 times (OR = 1.29; 95% CI: 1.00-1.66) more likely to have 4+ ANC than those living less than 5 km from the nearest health facility. CONCLUSIONS: Insofar as the financial barrier to ANC has been lifted and the geographical barrier reduced for the populations that live farther away from services through the Gratuité policy, then the Burkinabé government must make efforts to sustain the policy and ensure that benefits of the policy reach the targeted and its gains maximized

Prevalence of trypanosomes, salivary gland hypertrophy virus and Wolbachia in wild populations of tsetse flies from West Africa

Background: Tsetse flies are vectors of African trypanosomes, protozoan parasites that cause sleeping sickness (or human African trypanosomosis) in humans and nagana (or animal African trypanosomosis) in livestock. In addition to trypanosomes, four symbiotic bacteria Wigglesworthia glossinidia, Sodalis glossinidius, Wolbachia, Spiroplasma and one pathogen, the salivary gland hypertrophy virus (SGHV), have been reported in different tsetse species. We evaluated the prevalence and coinfection dynamics between Wolbachia, trypanosomes, and SGHV in four tsetse species (Glossina palpalis gambiensis, G. tachinoides, G. morsitans submorsitans, and G. medicorum) that were collected between 2008 and 2015 from 46 geographical locations in West Africa, i.e. Burkina Faso, Mali, Ghana, Guinea, and Senegal. Results: The results indicated an overall low prevalence of SGHV and Wolbachia and a high prevalence of trypanosomes in the sampled wild tsetse populations. The prevalence of all three infections varied among tsetse species and sample origin. The highest trypanosome prevalence was found in Glossina tachinoides (61.1%) from Ghana and in Glossina palpalis gambiensis (43.7%) from Senegal. The trypanosome prevalence in the four species from Burkina Faso was lower, i.e. 39.6% in Glossina medicorum, 18.08%; in Glossina morsitans submorsitans, 16.8%; in Glossina tachinoides and 10.5% in Glossina palpalis gambiensis. The trypanosome prevalence in Glossina palpalis gambiensis was lowest in Mali (6.9%) and Guinea (2.2%). The prevalence of SGHV and Wolbachia was very low irrespective of location or tsetse species with an average of 1.7% for SGHV and 1.0% for Wolbachia. In some cases, mixed infections with different trypanosome species were detected. The highest prevalence of coinfection was Trypanosoma vivax and other Trypanosoma species (9.5%) followed by coinfection of T. congolense with other trypanosomes (7.5%). The prevalence of coinfection of T. vivax and T. congolense was (1.0%) and no mixed infection of trypanosomes, SGHV and Wolbachia was detected. Conclusion: The results indicated a high rate of trypanosome infection in tsetse wild populations in West African countries but lower infection rate of both Wolbachia and SGHV. Double or triple mixed trypanosome infections were found. In addition, mixed trypanosome and SGHV infections existed however no mixed infections of trypanosome and/or SGHV with Wolbachia were found

Meningococcal carriage and cerebrospinal meningitis after MenAfriVac mass immunization in Burkina Faso

The aims of this study were to evaluate the impact of conjugate vaccine A, MenAfriVac, on Neisseria meningitidis (Nm) asymptomatic carriage and cerebrospinal meningitis in three health districts (Bogodogo, Kaya, and Dandé) of Burkina Faso. Asymptomatic carriage of Nm was assessed by performing cross-sectional studyrepeated (rounds 1 to 10) before and after introduction of the conjugate vaccine against serogroup A of N. meningitidis (NmA), MenAfriVac. In each round at least 1,500 people were enrolled in each district for a month. Data oncases of meningococcal meningitis in the three studied health districts were collected through meningitides epidemiological surveillance of Burkina Faso.Nm was identified in680 of 23,885 throat swabs before vaccination (2. 84%)withNmYasthe dominant serogroup(1.87%). During the same period (2009 and 2010), 891 cases of suspected meningitis were reported in the three health districts among whom 42 were due toNm (4.71%) withNmX (3.70%) asthe most frequently identified serogroup. After vaccination, Nm was identified in 1117 of 27,245 pharyngeal samples (6.42%); NmX (4.42%) wasthe dominantserogroup. From 2011 to 2013, 965 cases of suspected meningitis were reported in all health facilities in the three studied health districts located in the geographical study area; 91 was due toNm (9.43%) andNmWasthe most commonserogroup(52 cases= 5.38%).After introduction of conjugate vaccine A (MenAfriVac), the NmAserogroup almost disappeared both in asymptomatic carriers and in patients with cerebrospinal meningitis. However the presence of the NmW and NmXserogroups, which appear to have replaced serogroup A, is very worrying with regard to meningitis prevention and control in Burkina Faso. It appears necessary to strengthen surveillance and laboratory diagnosis of the different meningococcal serogroups circulating in Africa.Keywords: meningococcal meningitis, serogroups W and X, meningococcal carriage, MenAfriVac

Etiology and risk factors for meningitis during an outbreak in Batié Health District, Burkina Faso, January-March 2016

Introduction: On 16 March 2016, Batié Health District notified the Burkina Faso Ministry of Health Surveillance unit of 12 suspected cases of meningitis. During the same period, Batié´s neighboring districts in Côte d'Ivoire and Ghana were experiencing a meningitis epidemic. We investigated to establish the etiology and risk factors for the disease and to recommend prevention and control measures. Methods: We conducted unmatched case control study. A case was any person living in Batié with fever (temp. ≥ 38.5°C) and any of the following: neck stiffness, neurological disorder, bulging fontanelle, convulsion during January to April 2016 with cerebrospinal fluid (CSF) positive to PCR. Controls were non sick household members, neighbors or friends to the cases. We analyzed the investigation and laboratory records. We included all confirmed cases and two neighborhood controls per case. We used a standard questionnaire to collect data. We analyzed data by Epi info 7 and calculated odds ratio (ORs),adjusted odds ratios (AOR) and 95% confidence interval. We proceeded to univariate, bivariate, multivariate and logistic regression analysis. Results: We interviewed 93 participants including 31 meningitis cases and 62 controls. The median age of cases was 8 years old [2 months-55 years] and 6.5 years old [5 months-51 years] for controls. Streptococcus pneumoniae 16(51.61%), Neisseria meningitidis W 14(45.16%) and Haemophilus influenzae b 1(3.23%) were the identified germs. The independent risk factors identified were travel to meningitis affected areas (Adjusted odd ratio(AOR)=12[2.3-60],p=0.0029); >5 persons sharing bedroom (AOR=5.7[1.5-22],p=0.012) and rhinopharyngitis (AOR=26[1.8-380],p=0.017). Conclusion: Streptococcus pneumoniae and Neisseria meningitidis W caused the outbreak in Batié. The risk factors were overcrowding, travel to affected areas, and rhinopharyngitis. We recommended reactive vaccination against Neisseria meningitidis W, limited travel to affected areas and ventilation of rooms

Quality control and standardization of FACA® syrup

Sickle cell disease is a major public health problem. It is the first genetic disease in the world. FACA syrup offers an alternative treatment. It is a dry powder preparation of two components, the roots barks of Zanthoxylum zanthoxyloides Lam. (Rutaceae) Zepernick, Timler and Calotropis procera. Ait. R.B.r. (Asclepiadaceae). The product was developed at Institute for Research in Health Sciences (IRSS) from a traditional recipe used in Burkina Faso for treatment of sickle cell crises. This study aimed to establish physical-chemical, pharmaco technical and microbiological control parameters essential for the standardization of the phytomedicine. This valuation concerned specifications of moisture content, pH, the fingerprint by thin layer chromatography, pesticide residues, heavy metal content, microbial quality, and total ash. These charcteristics were determined by the methods prescribed by the World Health Organization (1998) and the European Pharmacopoeia 6th edition. The results have shown that dry syrups and reconstituted syrups were sweet, slightly spicy with a bitter after taste, a white room color and a faint odor. The density at the preparation was 0.985 and the pH was 5.93. After 2 months of storage in the laboratory, the organoleptic parameters of the reconstituted syrups have not changed. They were mold free, the density remained around 1 and the pH between 5 and 4. These parameters have shown that the quality of plants powders and these medicine comply with the recommendations of the European pharmacopoeia. Faca syrup may contribute to the better management of sickle cell disease in children

Mortalité néonatale au centre hospitalier universitaire de Tengandogo, Ouagadougou, Burkina Faso: une étude de cohorte retrospective: Neonatal mortality at Tengandogo University Hospital, Ouagadougou, Burkina Faso: a retrospective cohort study

Introduction: Selon l’organisation mondiale de la santé, les décès néonataux représentent 41% de la mortalité infanto-juvénile. L’Afrique subsaharienne a le taux de mortalité néonatale le plus élevé à 28‰. L’objectif de l’étude était de mesurer le taux de mortalité néonatale et d’identifier les facteurs associés au décès au Centre hospitalier universitaire de Tengandogo, Ouagadougou, Burkina Faso. Méthodes: Les nouveaux nés de 0 à 28 jours, hospitalisés entre le 1er janvier 2013 et le 31 décembre 2017 ont été inclus dans cette étude de cohorte rétrospective au service de néonatologie et de pédiatrie. Les informations ont été extraites à partir des dossiers cliniques. La survie a été estimée par la méthode de Kaplan Meier. Un modèle de Cox a permis d’identifier les facteurs associés. Résultats: Au total 641 nouveau-nés ont été inclus. Les enfants admis dès le premier jour de leur naissance représentaient 80%. La durée médiane de séjour était de 6 jours avec un intervalle interquartile de 3-12 jours. Les principaux diagnostics étaient la prématurité (36,05%), les infections néonatales (33,23%) et l’asphyxie (17,86%). Le taux de mortalité néonatale était de 22,25 pour 1000 personnes jours. Après ajustement, le poids de naissance inferieur 1500gramme (HRa = 4,13 ; IC 95% (2,58-6,67)) et la notion de réanimation à la naissance (HRa2,62 ; IC 95% [1,64-4,39)) étaient les facteurs de risque. Conclusion: Le taux de mortalité néonatale reste élevé. Le suivi prénatal, la prévention des infections, le renforcement des moyens de réanimation et la compétence des acteurs sont essentiels pour réduire ce taux. Introduction: According to the World Health Organization, neonatal deaths account for 41% of infant and child mortality. Sub-Saharan Africa has the highest neonatal mortality rate at 28‰. The objective of the study was to measure the neonatal mortality rate and identify factors associated with death at the Tengandogo University Hospital, Ouagadougou, Burkina Faso. Method: New-borns aged 0 to 28 days, hospitalised between 1 January 2013 and 31 December 2017 were included in this retrospective cohort study in the neonatology and paediatrics department. Information was extracted from clinical records. Survival was estimated by the Kaplan Meier method. A Cox model was used to identify associated factors. Results: A total of 641 new-borns were included. Children admitted on the first day of birth accounted for 80%. The median length of stay was 6 days with an interquartile range of 3-12 days. The main diagnoses were prematurity (36.05%), neonatal infections (33.23%) and asphyxia (17.86%). The neonatal mortality rate was 22.25 per 1000 person days. After adjustment, birth weight below 1500 grams (HRa = 4.13; 95% CI (2.58-6.67)) and the notion of resuscitation at birth (HRa2.62; 95% CI (1.64-4.39)) were the risk factors. Conclusion: The neonatal mortality rate remains high. Prenatal follow-up, infection prevention, strengthening of resuscitation resources and competence of actors are essential to reduce this rate
