Abstract Background In Gabon, children under 5 years of age and pregnant women are the populations who are most at risk of malaria. Despite the presence of accessible health facilities, the community-based management of childhood fever remains a very common practice in Gabon, which may have serious consequences on child health. As such, the objective of this descriptive cross-sectional survey is to assess the mothers’ perception and knowledge of malaria and its severity. Methods Different households were selected using the simple random sampling method. Results A total of 146 mothers from different households were interviewed in the city of Franceville, in southern Gabon. Among the households interviewed, 75.3% had a low monthly income (below the minimum monthly income of $272.73). Among the respondents, 98.6% of mothers had heard of malaria and 55.5% had heard of severe malaria. Regarding preventive measures, 83.6% of mothers used an insecticide-treated net as a means of protection. Self-medication was practiced by 68.5% of women (100/146). Discussion The use of health facilities was motivated by better care, the decision of the head of the family, but above all by the severity of the disease. Women identified fever as the main symptom of malaria, which could be beneficial for a quicker and more efficient management of the disease in children. Malaria educational campaigns should also increase awareness of severe forms of malaria and its manifestations. This study shows that Gabonese mothers react quickly when their children have fever. However, several external factors lead them to practice self-medication as a first resort. In this survey population, the practice of self-medication did not depend on social status, marital status, level of education, on the young age or inexperience of mothers (p > 0.05). Conclusions The data revealed that mothers may underestimate severe malaria and delay medical care by self-medicating, which can have detrimental effects for children and hinder the regression of the disease.

Abstract Introduction Malaria remains a significant public health problem in sub-Saharan Africa. Child mortality due to severe malaria remains high in developing countries despite improvements in malaria management and a better understanding of its pathophysiology. To address the lack of epidemiological studies on severe malaria in Gabon, this study describes the epidemiological aspects of severe malaria in rural, semi-rural, and urban areas of southeast Gabon. Methods Demographic, clinical, and laboratory data for children and adolescents aged 0–18 years were collected in 2019 from hospital records at three health facilities in southeastern Gabon. The patients included in the study were positive for P falciparum malaria diagnosed by microscopy with at least one of the malaria severity criteria. Results Severe malaria accounted for 18.8% (667/3552) of malaria cases. Children aged 0–5 years accounted for 71.8% (479/667) of all severe malaria cases. Adolescents over 15 years of age were the least affected by severe malaria with 4.2% (28/667). Across the study, severe anemia (49.0%, 327/667), convulsions (43.0%, 287/667), respiratory distress (5.1%, 34/667), and altered consciousness (4.8%, 32/667) were the most frequent clinical signs of severe malaria in children. Franceville was the locality most affected by severe malaria with 49.2% (328/667), followed by Koulamoutou with 42.0% (280/667) and Lastourville with 8.8% (59/667). Convulsions (50.6%, 166/328) and coma (6.1%, 20/328) were more frequent in children living in urban areas. In contrast, severe anemia (56.7%, 186/339) and jaundice (6.8%, 23/339) were more common in children living in semi-rural areas. Conclusion Severe malaria is more prevalent in urban areas in regions with a high malaria transmission intensity. However, in this study, the epidemiological characteristics of severe malaria were similar in the three settings (urban, rural, and semi-rural areas) despite different levels of urbanization. Nevertheless, the various signs of severity were more frequent in Franceville, an urban area. Children under 5 years of age remain the most vulnerable age group.

Abstract Background In Gabon, a new national malaria control policy was implemented in 2003. It resulted in a decrease in the number of malaria cases in the country. In March 2020, the disruption of routine health services due to the COVID-19 pandemic has led to an increase in cases and deaths due to malaria. However, in Franceville, south-east Gabon, no data on malaria cases recorded before, during and after the COVID-19 epidemic has been published. Thus, the objective of this study was to determine the epidemiological characteristics of malaria in Franceville from 2019 to 2021. Methods A retrospectively study of malaria cases was performed at the Hôpital de l’Amitié Sino-Gabonaise (HASG). Information regarding age, gender, malaria diagnosis by microscopy and hematology cell count were collected from laboratory registers from June 2019 to December 2021. Malaria data were analyzed and correlated with seasonal variations. Results The data of 12,695 febrile patients were collected from the laboratory registers of the HASG, among which 4252 (33.5%) patients were found positive for malaria. The malaria prevalence was 37.5% in 2020 year. This prevalence was highest compared to the 2019 (29.6%) and 2021 (31.5%) year (p 0.05). Conclusion The prevalence of malaria in Franceville was very high during COVID-19 pandemic. It is therefore necessary to strengthen existing interventions and implement more effective interventions.

Abstract Background In developing countries, health information system (HIS) is experiencing more and more difficulties to produce quality data. The lack of reliable health related information makes it difficult to develop effective health policies. In order to understand the organization of HIS in African countries, we undertook a literature review. Methods Our study was conducted using the PubMed and Scopus bibliographic search engines. The inclusion criteria were: (i) all articles published between 2005 and 2019, (ii) articles including in their title the keywords "health", "information", "systems", "system", "africa", "developing countries", "santé", "pays en développement", "Afrique", (iii) articles that are written in English or French, (iv) which deals with organizational and technical issues about HIS in African countries. Results Fourteen retrieved articles out of 2492 were included in the study, of which 13 (92.9%) were qualitative. All of them dealt with issues related to HIS in 12 African countries. All 12 countries (100.0%) had opted for a data warehouse approach to improve their HIS. This approach, supported by the DHIS2 system, has enabled providing reliable data. However, 11 out of the 12 countries (92.0%) frameworks were aligned with funding donors’ strategies and lacked any national strategy. Conclusion This study suggests that the lack of a national health information management strategy will always be a threat to HIS performance in African countries. Ideally, rigorous upstream thinking to strengthen HIS governance should be undertaken by defining and proposing a coherent conceptual framework to analyze and guide the development and integration of digital applications into HIS over the long term.

Abstract Background Malaria is one of the leading causes of morbidity and mortality in African countries. It is one of the leading causes of hospital visits and hospitalization in pediatric wards for children under 5 years old. Interestingly however, the economic burden of this disease remains unknown in these endemic countries including Gabon. The purpose of this study is to assess the direct hospital cost for the management of malaria in children under 5 years old at the Libreville University Hospital Centre (CHUL, Centre Hospitalier Universitaire de Libreville) in Gabon. Methods This research work is a retrospective study using a comprehensive review of medical records of patients seen at the CHUL over a two-year period extending from January 2018 through December 2019. The study focused on children under 5 years old, admitted for malaria in the paediatric ward of the CHUL. The analysis targeted specifically direct hospital costs, which excluded salary and wages of health care workers. The monetary currency used in this study was the CFA francs, as that currency is the one used in Central Africa (as reference, 1 Euro = 656 CFA francs). Results For the set timeframe, 778 patient records matched the study criteria. Thus, out of 778 admitted patients, 58.4% were male while 41.5% were female. Overall, the average age was 13.2 months (± 13.8 months). The total cost incurred by the hospital for the management of these 778 malaria patients was 94,922,925 CFA francs (144,699.58 €), for an average expense per patient topping at 122,008 CFA francs (185.99 €). The highest expenditure items were hospitalizations (44,200,000 CFA francs, 67,378.1 €), followed by drugs (26,394,425 CFA francs, 40,235.4 €) and biomedical examinations (14,036,000 CFA francs, 21,396.34 €). Conclusion The financial burden for managing malaria in the paediatric ward seems to be very high, not only for the hospital, but also for families in spite of the government medical insurance coverage in some cases. These findings bring new insights as to the urgency to develop policies that foster preventive initiatives over curative approaches in the management of malaria in children in endemic countries.

Abstract Background In sub-tropical countries, infectious diseases remain one of the main causes of mortality. Because of their lack of active immunity, pregnant women and their unborn children represent the most susceptible people. In Gabon, data on infectious diseases of pregnant women such as syphilis and rubella are either scarce or very old. Few studies have assessed T. gondii infection during pregnancy in the country. Here, we evaluate seroprevalence of HIV, HTVL-1, syphilis and T. gondii and rubella infection during antenatal care among women living in Franceville, Gabon. Methods A retrospective study was conducted on data collected from May 2007 to July 2010. After signing an informed written consent form, all pregnant women consulting in two hospitals of Franceville (Gabon) and in offices of maternity and childbirth health centers were included. Demographic and clinical data were collected. Serum samples were collected and analysed using immunological assays relevant for HIV (Genscreen HIV-1 version 2, Bio-Rad®, Marne la Roquette, France).HTLV-1 (Vironostika HTLV-1, Biomérieux®, Marcy l’Etoile, France), T. pallidum (TPHA/VDRL), BIOLABO®SA), rubella virus (Vidas Biomerieux®, Marcy l’Etoile, France) and T. gondii (Vidas Biomerieux®, Marcy l’Etoile, France) diagnoses were performed. Data analysis was done using the Stat view 5.0 software. Results A total of 973 pregnant women were assessed. The mean age was 25.84 ± 6.9 years, with a minimum age of 14.0 years and a maximum of 45.0 years. Women from 26 to 45 years old and unemployed women were the most prevalent: 41.93% and 77.18%, respectively. The prevalence of studied infectious diseases were 2.50% for syphilis, 2.88% for HTLV-1, 4.00% for HIV with no significant difference between them (p = 0.1). Seropositivity against rubella was higher (87.56%, n = 852) than seropositivity against T. gondii (57.35%, n = 557), (p
