Tuberculose bovine et conséquences associées dans la commune rurale de Tanghin-Dassouri au Burkina Faso
La tuberculose bovine est une zoonose majeure causĂ©e par la bactĂ©rie Mycobacterium bovis. Câest une maladie Ă fort impact hygiĂ©nique et Ă©conomique. Cette Ă©tude a eu pour objectif dâĂ©valuer la prĂ©valence de la tuberculose bovine Ă travers les saisies de 2018 Ă 2020 sur lâaire dâabattage de Yimdi avec les consĂ©quences Ă©conomiques et les comportements Ă risque associĂ©s Ă cette zoonose dans la commune rurale de Tanghin-Dassouri au Burkina Faso. Ainsi, une Ă©tude de cohorte rĂ©trospective a Ă©tĂ© rĂ©alisĂ©e. Les pertes Ă©conomiques et les comportements Ă risque envers cette zoonose ont Ă©tĂ© dĂ©terminĂ©s par un questionnaire. Sur les 35 796 bovins abattus, 722 poumons ont Ă©tĂ© saisies soit une prĂ©valence de 2,0±0,2% de saisies partielles de poumons liĂ©es Ă la tuberculose. Aucune carcasse de bovin nâa Ă©tĂ© totalement saisie. Les pertes Ă©conomiques ont Ă©tĂ© Ă©valuĂ©es Ă 2 166 000 FCFA. Les comportements Ă risque les plus frĂ©quemment observĂ©s chez les humains ont Ă©tĂ© la vente des protĂ©ines animales insalubres, la consommation de la viande et des abats mal cuits et la consommation de lait cru ou de lait caillĂ© non pasteurisĂ©s et de fromage frais. Au regard de ces rĂ©sultats et pour une meilleure sĂ©curitĂ© sanitaire des denrĂ©es alimentaires dâorigine animale, cette Ă©tude doit ĂȘtre Ă©largie aux autres abattoirs et aires dâabattage du Burkina Faso avec une implication effective de toutes les municipalitĂ©s dans la lutte contre les abattages clandestins. La confirmation au laboratoire et une sensibilisation des bouchers sur les risques de transmissions zoonotiques de la tuberculose sont nĂ©cessaires.
English title: Bovine tuberculosis and associated consequences in the rural commune of Tanghin-Dassouri in Burkina Faso
Bovine tuberculosis is a major zoonotic disease caused by the bacterium Mycobacterium bovis. It is a disease with a high hygienic and economic impact. The objective of this study was to assess the prevalence of bovine tuberculosis through seizures from 2018 to 2020 on the Yimdi slaughter area with the economic consequences and risk behaviours associated with this zoonotic disease in the rural commune of Tanghin-Dassouri in Burkina Faso. Thus, a retrospective cohort study was conducted. Economic losses and risk behaviours towards this zoonosis were determined by a questionnaire. Of the 35,796 cattle slaughtered, 722 lungs were seized, representing a prevalence of 2.0±0.2% partial TB-related lung seizures. No cattle carcasses were fully seized. Economic losses were estimated at 2,166,000 FCFA. The most common risk behaviours observed in humans were the sale of unhealthy animal proteins, the consumption of undercooked meat and offal, and the consumption of unpasteurized raw or curdled milk and fresh cheese. In the light of these results and in order to improve the safety of foodstuffs of animal origin, this study should be extended to other slaughterhouses and slaughter areas in Burkina Faso with the effective involvement of all municipalities in the fight against illegal slaughter. Laboratory confirmation and awarenessraising of butchers on the risks of zoonotic transmission of tuberculosis are necessary
Preliminary results of official influenza and acute respiratory infection surveillance in two towns of Burkina Faso, 2013â2015
Abstract Background In 2010, influenza, influenza-like illness (ILI) and acute respiratory infection (ARI) surveillance was established by the government of Burkina Faso. We provide preliminary descriptive results from this surveillance activity. Methods The study period was 2013 through 2015. Two primary healthcare facilities in Bobo-Dioulasso district reported ILI in outpatients. Influenza virology, using reverse transcription-polymerase chain reaction (rRT-PCR), was available for a proportion of ILI patients. One hospital, in the capital Ouagadougou, reported ARI in both outpatients and inpatients (hospitalized). Inpatients admitted with ARI were considered severe ARI (SARI). We estimated the proportion of primary care outpatient visits that were ILI, and the proportion of those that were due to influenza, by age. We estimated the proportion of hospital outpatient visits that were ARI and the proportion of those that were SARI, by age. Results Among combined outpatient visits in the Bobo-Dioulasso facilities, 19.6% were for ILI. One half (49.9%) of outpatient visits in infants and 30.9% in 1â4Â year-olds were ILI. Among ILI outpatient visits 14.8% were due to influenza virus and, of these, 58.5% were type A and 41.5% type B. At the Ouagadougou hospital, 6.7% of outpatient visits were ARI, and 22.3% of those were SARI. The highest proportions of ARI were among infants (19.8%) and 1â4Â year-olds (16.0%). The proportion of ARI that was SARI was highest among â„15Â year-olds (31.5%) followed by 1â4Â year-olds (22.4%). Overall, 4.1% of SARI patients died. Conclusions These preliminary data indicate the importance of respiratory infections among health care attendances in Burkina Faso, and influenza may be an important contributor to these
Coinfections with SARSâCoVâ2 variants and influenza virus during the 2019 Coronavirus disease pandemic in Burkina Faso: A surveillance study
Abstract Background and Aim Severe acute respiratory syndrome coronavirus 2 (SARSâCoVâ2) particularly the variants of concern coinfections with influenza is a public health concern in Africa. We aimed to characterize the SARSâCoVâ2 variants and determine the rate of coinfections with influenza in Burkina Faso. Methods COVIDâ19 surveillance study was conducted between August 2021 and January 2022 using reverse transcription polymerase chain reaction (RTâPCR). Positive specimens were further screened for SARSâCoVâ2 variants using the multiple variants realâtime PCR kits. In addition, influenza virus strains were detected by RTâPCR in SARSâCoVâ2 positive specimens using the CDC primers, probes, and protocols. Results Of 324 specimens assessed, the Omicron and Delta variants of SARSâCoVâ2 were the most prevalent with 27.2% [95% confident interval (CI): 22.5â32.4] and 22.2% [95% CI: 17.9â27.2], respectively. The Beta and Gamma variants were detected in 4.3% [95% CI: 2.4â7.1] and 0.3% [95% CI: 0.0â1.7], respectively. Coinfections of Omicron and Beta variants were reported in 21.3% [95% CI: 17.0â26.2], Omicron and Delta variants in 1.2% [95% CI: 0.3â3.1] of specimens, and the OmicronâGamma variants' coinfections in 0.6% [95% CI: 0.1â2.2]. One COVIDâ19 specimen with an undetected SARSâCoVâ2 variant was also tested positive for the seasonal influenza A (H3N2) virus. No cases of pandemic influenza A (H1N1)pdm09, seasonal A/H1N1, and influenza B were detected. Conclusions The current World Health Organization SARSâCoVâ2 variants of concern were prevalent and their coinfections with influenza were uncommon. Continuous surveillance of both pathogens is, however, needed because of their public health implications
Dengue Fever in Burkina Faso, 2016
We report 1,327 probable cases of dengue in Burkina Faso in 2016. Of 35 serum samples tested by a trioplex test, 19 were confirmed dengue virus (DENV)âpositive: 11 DENV-2, 6 DENV-3, 2 nontypeable, and 1 DENV-2/DENV-3 co-infection. Molecular testing should be conducted to correctly identify causative agents in this complex infectious disease landscape
Predictors of severity and prolonged hospital stay of viral acute respiratory infections (ARI) among children under five years in Burkina Faso, 2016â2019
Abstract Background Viruses are the leading etiology of acute respiratory infections (ARI) in children. However, there is limited knowledge on drivers of severe acute respiratory infection (SARI) cases involving viruses. We aimed to identify factors associated with severity and prolonged hospitalization of viral SARI among childrenââ7 days). Conclusion Younger age, malnutrition, codetection of Klebsiella pneumoniae, and illness during the rainy season were associated with very severe cases and prolonged hospitalization of SARI involving viruses in children under five years. These findings emphasize the need for preventive actions targeting these factors in young children
