BackgroundToxoplasmosis is one of the common worldwide parasitic zoonosis due to Toxoplasma gondii (T. gondii). Toxoplasmosis during pregnancy can result in fetal and neonatal death or various congenital defects. The aim of this study was to assess the seroprevalence and risk factors of T. gondii infection in pregnant women following antenatal care (ANC) services at Bobo Dioulasso.MethodsA cross-sectional study was conducted enrolling a sample of 316 pregnant women attending ANC at centers for maternal and child health of Bobo-Dioulasso town from March 2013 to February 2014. Data on socio-demographic and potential risk factors were collected from each study participant using structured questionnaire through face-to-face interview. Moreover, venous blood specimens were collected and tested for IgM and IgG anti-T. gondii antibodies by enzyme-linked immunosorbent assay and enzyme linked fluorescent assay, respectively. Multivariable logistic regression modeling was used to identify the potential predictor variables for T. gondii infection.ResultsThe overall seroprevalence for T. gondii infection was 31.1% (98/316). All the pregnant women were positive for IgG anti-bodies exclusively. Multivariable logistic regression analysis showed that having at least a secondary education level (AOR = 2.23; 95% CI: [1.04–4.63]); being urban resident (AOR = 2.81; 95% CI: [1.24–6.86]) and the consumption of meat combination (pork + beef + mutton + wild meat + poultry) (AOR = 4.00; 95% CI: [1.06–15.24]) were potential risk factors of T. gondii infection.ConclusionToxoplasmosis is frequent in pregnant women and studies that show incidence of T. gondii among the neonates have to be done to introduce routine antenatal screening program to control congenital toxoplasmosis. There is the need for preventive measures such as education of pregnant women about the transmission routes and prevention methods of toxoplasmosis at ANC clinics.
We conducted a systematic review of healthcare-associated outbreaks and cross-sectional surveys related to the contamination of antiseptics, disinfectants, and hand hygiene products in healthcare settings in low- and middle-income countries (PROSPERO CRD42021266271). Risk of bias was assessed by selected items of the ORION and MICRO checklists. From 1977 onwards, 13 outbreaks and 25 cross-sectional surveys were found: 20 from Asia and 13 from Africa. Products most associated with outbreaks were water-based chlorhexidine, chlorhexidine-quaternary ammonium compound combinations (7/13), and liquid soap products (4/13). Enterobacterales (including multidrug-resistant Enterobacter cloacae, Klebsiella pneumoniae, and Serratia marcescens) and non-fermentative Gram-negative rods were found in 5 and 7 outbreaks and in 34.1% and 42.6% of 164 isolates, respectively, from cross-sectional surveys. Risk factors included preparation (place, utensils, or tap water high and incorrect dilutions), containers (reused, recycled, or inadequate reprocessing), and practices (topping-up or too long use). Potential biases were microbiological methods (neutralizers) and incomplete description of products’ identity, selection, and denominators. External validity was compromised by low representativeness for remote rural settings and low-income countries in sub-Saharan Africa. Outstanding issues were water quality, biofilm control, field-adapted containers and reprocessing, in-country production, healthcare providers’ practices, and the role of bar soap. A list of “best practices” to mitigate product contamination was compiled.
BackgroundGastrointestinal parasites infections are widespread in Africa and their prevalence infections vary from country to country. This study aimed at assessing the prevalence of opportunistic intestinal parasites infection and other gastrointestinal parasites infection among patients attending the laboratory of Parasitology and Mycology of the University Hospital Souro Sanou of Bobo-Dioulasso.MethodsA hospital cross-sectional based study was conducted from April to August, 2012. Participants were persons whom parasitological examination of stools has been prescribed by a clinician. The stools examination methods included direct wet saline examination, lugol’s iodine staining technique, formol-ether concentration and modified Ziehl-Neelsen staining. We recorded age and sex information for each patient.ResultsThe overall prevalence of intestinal parasite infections was 65.3 % (190/291). Majority of the parasitic infections was waterborne (64.3 %) consisting of high prevalence of Cryptosporidium sp. (26.5 %) and Entamoeba histolytica/dispar (23.4 %). The prevalence of opportunistic parasites was 28.9 % and Cryptosporidium sp. was the most prevalent species followed by Blastocystis sp. (1.0 %), Cyclospora sp. (0.7 %) and Isospora belli (0.7 %). The prevalence of intestinal helminthes was 1.7 %.ConclusionsThe prevalence of intestinal parasitism in general remains high in Bobo-Dioulasso requiring the establishment of adequate diagnostic techniques, treatment and prevention.
Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the national demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0.8% of the population) and a 3.4% incidence of cryptococcosis in hospitals, it is estimated that 459 patients per year develop cryptococcosis. For pneumocystosis, it is suggested that 1013 new cases occur every year. Taking into account the local TB frequency (population prevalence at 0.052%), we estimate the prevalence of chronic pulmonary aspergillosis at 1120 cases. Severe forms of asthma with fungal sensitization and allergic bronchopulmonary aspergillosis are estimated to affect 7429 and 5628 cases, respectively. Vulvovaginal candidiasis may affect 179,000 women, and almost 1,000,000 children may suffer from tinea capitis. Globally, we estimate that roughly 1.4 million people in Burkina Faso (7.51% of the population) suffer from a serious fungal infection. These data should be used to drive future epidemiological studies, diagnostic approaches, and therapeutic strategies.
BackgroundBecause infections with Schistosoma Haematobium usually peak in childhood, the majority of studies on schistosomiasis have focused on school-aged children. This study aimed to assess the epidemiological and clinical aspects of urogenital schistosomiasis in women in Burkina Faso, West Africa.MethodsA cross-sectional study was conducted in a mesoendemic region (Kombissiri) and a hyperendemic region (Dori) for schistosomiasis in Burkina Faso. A total of 287 females aged 5 to 50 years were included in the study. S. haematobium infection was assessed using the urine filtration method and dipsticks were used for the detection of hematuria. Interviews were conducted to identify clinical aspects and risk factors related to urogenital schistosomiasis.ResultsThe overall prevalence of S. haematobium infection in Dori was 21.3 %, where as Kombissiri was less affected with a prevalence of 4.6 %. The most affected age group was the 10- to 14-year-olds (41.2 %), followed by the 15- to 19-year-olds (26.3 %). Risk factors significantly associated with schistosomiasis (P <0.05) were place of residence, age, contact with open water in the past year, and distance of home to open water. The percentage of participants who had contact with open water was significantly higher among the women living in Dori compared to Kombissiri. Females over 15 years of age showed a significant higher rate of water contact compared to the 5- to 15-year-olds. A significant correlation between schistosomiasis and hematuria was established. Microhematuria showed a sensitivity of 80.6 %, a specificity of 92.7 %, and a positive predictive value of 61.7 %, whereas macrohematuria had a sensitivity of 47.2 %, a specificity of 99.2 %, and a positive predictive value of 89.5 %. The mass distribution of praziquantel in Burkina Faso is well established. However, over half of the participants with schistosomiasis in this study said they took praziquantel in the past 6 months, which indicates a high reinfection rate. This may be associated with a lack of knowledge about the transmission of schistosomiasis. Only 6 % of the participants in Kombissiri and 1.5 % in Dori knew about the correct mode of transmission.ConclusionsThe results of our study indicate that distribution campaigns should be extended from school-aged children to young women. Our data also demonstrate the necessity of combining already established mass distribution campaigns with information campaigns, so that long-term elimination, or at least reduction, of schistosomiasis can be achieved.Electronic supplementary materialThe online version of this article (doi:10.1186/s40249-016-0174-1) contains supplementary material, which is available to authorized users.
