“…The prevalence of S. haematobium reported in the present study was higher than the mean global prevalence of 13.44% during pregnancy estimated from various countries worldwide [33]. Our prevalence was similar to that reported among Nigeria pregnant women [34] while it's higher than previously reported values in other countries such as Cameroon [10], Tanzania [35] where prevalence were less than 5%. However, the infection rate of S. mansoni in our study was lower than the global prevalence of 12.18% [33].…”

“…It is estimated that around 40 millions of women of reproductive age are affected by schistosomiasis, worldwide, with approximately 10 million infected per year during pregnancy in Africa [8]. These estimations are most based on result of standard microscopy [9][10][11] and few studies are used molecular or immunological techniques [12] to detect Schistosoma infection in urine or stool samples.…”

Background Schistosomiasis remains a public health concern worldwide. It is responsible for more than 240 million cases in 78 countries, 40 million of whom are women of childbearing age. In the Senegal River basin, both Schistosoma haematobium and Schistosoma mansoni are very prevalent in school-age children. However, there is a lack of information on burden of schistosomiasis in pregnant women, which can cause complications for the pregnancy outcome. The aim of this study was to determine the prevalence and risk factors associated with infection in pregnant women. Methods We conducted a prospective cross-sectional study of pregnant women attending antenatal clinics at the health center of the Senegalese sugar company and at the hospital of Richard Toll between August and December 2021. The urine and stool samples collected were examined using microscopy techniques and quantitative polymerase chain reaction (qPCR) to detect the presence of S. haematobium and S. mansoni. Urine were previously tested using urine reagent strips to detect hematuria and proteinuria. Sociodemographic, clinical and biological data were collected from each participant. The data were analyzed using logistic regression model. Results Among the 298 women examined for the infection by microscopic, 65 (21.81%) were infected with urogenital schistosomiasis, 10 (3.36%) with intestinal schistosomiasis and 4 (1.34%) were co-infected with both types of schistosomiasis. Out of the 288 samples tested by qPCR, 146 (48.99%) were positive for S. haematobium, 49 (35.51%) for S. mansoni and 22 (15.94%) for both species (co-infection). Schistosomiasis was significantly associated with the presence of blood and the protein on strips (p < 0.05). Conclusion This study has revealed a high prevalence of schistosomiasis in pregnant women in Senegal. The qPCR allowed us to detect more cases compared to the microscopy. There is a need to conduct more studies to understand the real burden of the disease and to set up a surveillance system to prevent pregnancy-related complications.

“…In some health areas of Cameroon, such as Barombi Kotto the prevalence amongst school-aged children is over 25% [16]. A study investigating schistosomiasis prevalence amongst pregnant women in Cameroon found a prevalence of 31.9% [17]. School-aged children (5 to 14 years old), fishermen and farmers are known high-risk groups for Schistosomiasis infection as well as women and girls as gender roles mean that many of their daily activities include fresh water contact in the washing of clothes and dishes, fetching water for bathing, drinking and other activities [18].…”

Background: The UN's Sustainable Development Goals (SDGs) which pledge to leave no one behind for Universal health coverage (UHC) raise the importance of ensuring equitable health outcomes and healthcare delivery. As Neglected Tropical Diseases (NTDs) affect the most disadvantaged and hard to reach populations, they are considered a litmus test for Universal health coverage. Objective: Here, we assess the challenges of implementing Mass Drug Administrations (MDAs) for schistosomiasis prevention and control, in a context of expanded treatment where both community and school-based distribution were carried out, assessing which groups are missed and developing strategies to enhance equity. Methods: This is a qualitative study applying ethnographic observations, in-depth interviews (109) and focus group discussions (6) with key informants and other community members. Participants included community drug distributors, teachers, health workers, and implementing partners across four schistosomiasis endemic regions in Cameroon. Data collected were analysed thematically. Results: Programme implementation gaps have created circumstances where indigenous farmers (originally from the region) and migrating farmers (not originally from the region known as 'strangers' and 'farm hands'), women of reproductive age and school-aged children are continuously missed in MDA efforts in Cameroon. Key implementation challenges that limit access to MDA within this context include inadequate sensitization campaigns that don't sufficiently build trust with different groups; limits in CDD training around pregnancy and reproductive health; lack of alignment between distribution and community availability and the exclusion of existing formal and informal governance structures that have established trusting community relationships. Conclusion: Through identifying key populations missed in MDAs within specific contexts, we highlight how social inclusion and equity could be increased within the Cameroonian context. A main recommendation is to strengthen trust at the community level and work with established partnerships and local governance structures that can support sustainable solutions for more equitable MDA campaigns.

“…However, it was higher than the finding from Northwest Ethiopia (2.2%) [ 12 ]; Wondo Genet district, Southern Ethiopia (2.3%) [ 9 ]; and Wolayita Sodo Town, Southern Ethiopia (0.6%) [ 31 ]. But it was lower than that of the studies conducted in Mecha District, Northwest Ethiopia (17.4%) [ 22 ], Waja-Timuga, District of Alamata, Northern Ethiopia (73.9%) [ 41 ]; Cameroon (28.01%) [ 42 ]; and Uganda (36.4%) [ 37 ]. The variations in S. mansoni infection could be due to the differences in the geographical areas, environmental pollution with urine and feces, the habit of crossing and bathing in river waters, eating uncooked vegetables and foods, and cercariae-infested water sources [ 41 ].…”

Background. A cross-sectional study was conducted from November 2019 to March 2020 to determine the prevalence and associated risk factors of intestinal parasitic infections (IPIs) among pregnant women attending antenatal care (ANC) at Yifag Health Center. Methods. The data were collected by a questionnaire interview technique and collecting the stool samples from each pregnant woman. Wet-mount and formol-ether concentration techniques were applied to identify the IPIs. Data were analyzed using SPSS, version 25, and P -values < 0.05 were considered statistically significant. Results. Out of the total 280 pregnant women who were selected using a simple random sampling technique, 277 participated in the questionnaire survey and gave stool samples (a response rate of 98.9%). The prevalence of IPIs among pregnant women was 53.4% (95% CI: 47.37, 59.42). Taenia species (18.1%) was the predominant parasite followed by Giardia lamblia (12.6%), Entamoeba histolytica/dispar (9.4%), hookworms (9%), Ascaris lumbricoides (4%), Schistosoma mansoni (3.2%), Hymenolepis nana (0.7%), Strongyloides stercoralis (0.4%), and Enterobius vermicularis (0.4%). Eating raw vegetables (AOR = 2.721; 95% CI: 1.266, 5.849; P = 0.010 ) and poor personal hygiene (AOR = 4.015; 95% CI: 1.456, 11.07; P = 0.007 ) were associated risk factors for G. lamblia, while eating raw meat (AOR = 2.477; 95% CI: 1.252, 4.902; P = 0.009 ) for Taenia species infections. The prevalence of intestinal parasites was high and still a health burden to the pregnant women in the study area. We recommend avoiding eating raw meat, strengthening sanitation and hygiene programs, and routine deworming of pregnant mothers to reduce the burden of IPIs among pregnant women.
