Economic viability and factors affecting farmers’ willingness to pay for adopting small-scale biogas plants in rural areas of Cameroon

This study provides an in-depth economic analysis to aid decision-making in the adoption of small-scale biogas technology in rural areas of Cameroon. It also provides evidence of the field investment characteristics of the biogas energy supply in rural areas of Cameroon. The methodology focused on assessing the economic viability of different sizes of biogas plants and the willingness of farmers to pay for the same. A sample of 180 farmers was selected for the study. Data collection was carried out from December 2020 to May 2021 using a questionnaire survey and participant observation. The results show that all small-scale biogas plants are economically viable. Benefit-cost ratios were 1.01, 1.19, 1.50, 1.02, 1.21 and 2.04 for the 4 m3, 6 m3, 8 m3, 10 m3, 20 m3, and 25 m3 biogas plants. The net present values in US dollars (USD) were 959, 1790, 2695, 2658, 6047, and 12267 for the 4 m3, 6 m3, 8 m3, 10 m3, 20 m3, and 25 m3 biogas plants, respectively. The internal rate of return was higher than the applied discount rate of 12 %. The minimum payback period of 2.24 years was recorded for the 25 m3 while the maximum of 3.37 years was recorded for the 10 m3 biogas plants, respectively. With a disproportionate increase in the cost of biogas plants by 20 % and a 20 % decrease in benefits with a discount factor, the net returns are positive, indicating that all biogas plants are economically viable. The mean willingness to pay is estimated at 13 USD or 8000 FCFA. This resulted in an average repayment period of 11.5 years. The provision of extension services, financial incentives, and regulation of the small-scale biogas market will motivate farmers to adopt the technology.

Utility of plasma anti-gSG6-P1 IgG levels in determining changes in Anopheles gambiae bite rates in a rural area of Cameroon

The applicability of the specific human IgG antibody response to Anopheles gambiae salivary Gland Protein-6 peptide 1 (gSG6-P1 salivary peptide) as a biomarker able to distinguish the level of exposure to mosquito bites according to seasonal variations has not yet been evaluated in Central African regions. The study aimed to provide the first reliable data on the IgG anti-gSG6-P1 response in rural area in Cameroon according to the dry- and rainy-season. Between May and December 2020, dry blood samples were collected from people living in the Bankeng village in the forest area of the Centre region of Cameroon. Malaria infection was determined by thick-blood smear microscopy and multiplex PCR. The level of IgG anti-gSG6-P1 response, was assessed by enzyme-linked immunosorbent assay. Anopheles density and aggressiveness were assessed using human landing catches. The prevalence of malaria infection remains significantly higher in the rainy season than in the dry season (77.57% vs 61.44%; p = 0.0001). The specific anti-gSG6-P1 IgG response could be detected in individuals exposed to few mosquito bites and showed inter-individual heterogeneity even when living in the same exposure area. In both seasons, the level of anti-gSG6-P1 IgG response was not significantly different between Plasmodium infected and non-infected individuals. Mosquito bites were more aggressive in the rainy season compared to the dry season (human biting rate-HBR of 15.05 b/p/n vs 1.5 b/p/n) where mosquito density was very low. Infected mosquitoes were found only during the rainy season (sporozoite rate = 10.63% and entomological inoculation rate-EIR = 1.42 ib/p/n). The level of IgG anti-gSG6-P1 response was significantly higher in the rainy season and correlated with HBR (p ˂ 0.0001). This study highlights the high heterogeneity of individual’s exposure to the Anopheles gambiae s.l vector bites depending on the transmission season in the same area. These findings reinforce the usefulness of the anti-gSG6-P1 IgG response as an accurate immunological biomarker for detecting individual exposure to Anopheles gambiae s.l. bites during the low risk period of malaria transmission in rural areas and for the differentiating the level of exposure to mosquitoes.

Prevalence and associated factors of coexisting forms of malnutrition in children under 5 years age in a rural area of Cameroon.

Malnutrition of children under 5 years of age is persistent in Cameroon principally in rural areas. Moreover, there is limited knowledge of coexisting forms of malnutrition (CFM) among children of this age. Therefore, the aim of this study was to assess the prevalence of CFM in a cohort of children under 5 years and to identify the associated factors. A cross-sectional study was conducted in the Health Districts of the locality of Dschang in the West region of Cameroon between June 2021 to November 2021. Data were collected from 200 under-five children of both sexes and an interviewer-administered questionnaire was administered to consented children's mothers/guardians. Malnutrition in children was assessed by WHO growth standards (weight-for-height, weight-for-age, height-for-age and body mass index-for-age). The different CFM were defined by the presence of two autonomous forms of malnutrition in the same child. Logistic regression analyses were done to identify factors associated to different coexisting forms of malnutrition. The results obtained showed prevalences of 4.20% for the coexistence of underweight with wasting, 7.8% for the coexistence of underweight with stunting and 14.8% for the coexistence of stunting with overweight. Lower maternal age (15-24 years old; OR = 0.09; p = 0.05) and lower education level (primary education, OR = 23.33; p = 0.00) were associated with the coexistence of underweight with wasting. Marital status (single mother, OR = 0.28; p = 0.00) was associated to the coexistence of stunting with overweight/obesity. The findings of this study provide evidence on the coexistence of different forms of malnutrition among children below five years of age in rural area of Cameroon. These finding would guide future research, policies, and programs on the management of malnutrition in rural areas of Cameroon.

Advancing Adherence and Compliance to Personal Protective Equipment Policies among Health Care Workers - Insights from a Groundbreaking Case Study in Cameroon

Personal protective equipment (P PE) rules must be respected and followed to the letter of healthcare professionals in Cameroon to avoid the transmission of infectious diseases. This research proposes solutions to the problems of non-adherence and noncompliance among healthcare workers in Cameroon towards PPE rules. Inadequate access to suitable PPE, discomfort when wearing PPE during poor quality, and a lack of training on correct PPE use are just a few of these obstacles amongst HCWs in Cameroon. Hospitals and healthcare facilities should prioritize offering thorough instruction on PPE use and pinpoint the need to adhere consistently to PPE rules to remove these obstacles. They should also ensure that all healthcare personnel have access to and a sufficient supply of the proper PPE. Through the organization of impromptu visits by surveillance teams to identify areas of support and training, there is a need for assistance from government bodies and public health groups in creating awareness of the security value of PPE use among healthcare professionals. There is a lack of PPE in health care settings in rural areas in Cameroon, thus a need for an adequate supply. Then can we put appropriate PPE policies and practices for HCWs in Cameroon, as they will keep to it. Healthcare professionals in Cameroon must comprehend that following PPE standards protects not just their selves from diseases but also their patients, coworkers, and communities. We are accountable for ensuring everyone's safety and wellbeing, and adhering to PPE regulations is an essential first step.

Variation in Household Violence and Maternal Autonomy in Rural and Urban Areas: Their Effect on Child Health in Cameroon

This study examines the variations in household violence and maternal autonomy in rural and urban areas and their effect on child health in Cameroon. Using data from Cameron Demographic Health Survey (CDHS, 2018), a mixed-method approach (Ordinary Lease Square Regression and the Oaxaca-Blinder decomposition method) was used for the analysis. The study found that household violence had an insignificant negative effect on child health while maternal autonomy exhibited a very significant positive effect on child health globally, in rural and in urban areas in Cameroon. Also, the rates of household violence and maternal autonomy are significantly higher in urban areas than in rural areas in Cameroon. Policy recommendations includes raising awareness, providing educational and economic opportunities for women, improving health care services and strengthening legal framework to combat violence while strengthening maternal autonomy through educational and economic initiatives which improves their own and child health in both rural and urban settings in Cameroon.

Intestinal cystic lymphangioma.

A 7-year-old girl, coming from a rural area in Cameroon, presented to the emergency department with a 3-months history of abdominal pain. Her family also reported vomiting and minimal food intake for two weeks. Physical examination showed a palpable and mobile abdominal mass. An ultrasound showed a large intrabdominal multicystic lesion of about 10cm, close to the intestine and with no solid lesions in other organs. A laparotomy was scheduled and a mobile mass dependent on the jejunum was found. The mass caused an intestinal obstruction and was composed of several large cysts with whitish fluid. Excision of the mass and resection of a short segment of small bowel were performed. Intestinal cystic lymphangioma is a rare congenital malformation that normally presents with abdominal pain and distension. Abdominal ultrasonography is the procedure of choice for the diagnosis. Intestinal resection and anastomosis (while the cyst is normally intimate attached to the bowel) is an effective treatment.

Knowledge, Attitude, and Practices regarding Obesity among Population of Urban (Douala) and Rural (Manjo) Areas in Cameroon.

Knowledge, attitude, and practice (KAP) studies have recently been suggested as a useful tool to understand the specificity of the population related to a disease. However, in Cameroon, there is a lack of information based on KAP studies regarding obesity. This study has been designed to collect basic indicators on the KAP of the populations regarding overweight and obesity in urban and rural areas in Cameroon (Douala and Manjo). For this purpose, an epidemiological community-based cross-sectional descriptive study was conducted in these two areas using a well-structured questionnaire. Sociodemographic and medical characteristics and KAP information were assessed. For the quantification of KAP, a score varying from 0 (poor knowledge, attitude, or practices) to 100 (good knowledge, attitude, or practices) was attributed for each question. Correlations between knowledge, attitude, and practice were determined using inferential statistics tests which were χ2 test, independent Student t-test, ANOVA (followed by Tukey's post hoc test), and Pearson correlation coefficient. Results reveal that living in a rural area (Manjo), being overweight or obese, having complete secondary education, and being married increase the knowledge and the practice score. There is a strong and positive correlation between knowledge and practice score. However, there is no association between attitude and practice and between attitude and knowledge. Reducing the disparities between knowledge, attitude, and practices constitutes a serious track in a holistic strategy for the management of obesity in these areas.

The design and development of a study protocol to investigate Onchocerca volvulus, Loa loa and Mansonella perstans-mediated modulation of the metabolic and immunological profile in lean and obese individuals in Cameroon.

Life-style metabolic diseases are steadily rising, not only in developed countries, but also in low- and middle-income countries, presenting a global health problem. Metabolic disorders like type 2 diabetes and cardiovascular diseases are among the ten leading causes of death defined by the WHO in 2019. Results from animal and observational human studies suggest a connection between the decline in human helminth infections and rise of life-style-associated metabolic diseases in developing regions. This trial was designed to investigate filarial infections and their impact on metabolic diseases in Cameroon. We hypothesize that the induction of regulatory immune responses during filarial infection reduces obesity-induced low-grade inflammatory immune responses and thereby improves metabolic parameters, whereas anthelmintic treatment abolishes this protective effect. Participants infected with Mansonella perstans, Onchocerca volvulus and/or Loa loa being lean (BMI <25), overweight (BMI >25 and <30) or clinically obese (BMI ≥30) from Littoral regions of Cameroon will be evaluated for their parasitological, immunological, metabolic and biochemical profile before and after treatment of their parasitic infections. Anthropomorphic measurements and a detailed questionnaire will complement our analysis. The investigation will assess blood immune cell populations, serum adipokines and cytokines that could be influenced by the parasite infection and/or metabolic diseases. Further, parameters like blood glucose, homeostatic model assessment of insulin resistance (HOMA-IR), circulating lipids and circulating makers of liver function will be monitored. Parameters will be assessed before treatment, 12 and 18 months after treatment. The focus of this study is to obtain a comprehensive metabolic profile of the participants in rural areas of Cameroon and to investigate the relationship between filarial immunomodulation and metabolic diseases. This study will elucidate the effect of anti-filarial treatment on the metabolic and immunological parameters that partake in the development of insulin resistance, narrowing in on a potential protective effect of filarial infections on metabolic diseases. doi.org/10.1186/ISRCTN43845142, ISRCTN43845142 February 2020 Trial title Effects of filarial parasite infection on type 2 diabetes Issue date: 27.10.22, V.1.

Integrated Water Management in Mountain Communities: The Case of Feutap in the Municipality of Bangangté, Cameroon

The whole population of Feutap still collects drinking water from two protected springs, some 1 km away from this small rural agglomeration. For many generations, the only improvement has been the protection of the springs during the 1980s. The resulting high incidence of gastrointestinal infections continues to hinder the socioeconomic development of this mountain community. This dynamic wherein “poverty begets disease, and disease begets poverty” seems endless given the number of water improvement programs and other health-focused campaigns in rural areas of Cameroon since the 1960s. Fortunately, the hydrographic regime of Feutap and its geographical situation enable the implementation of the Kilimanjaro Concept (KC), wherein rainwater is quantitatively harvested, partly infiltrated, and largely stored to (i) meet the whole-year water needs of the population, (ii) create new ecosystems, and (iii) enable irrigated agriculture. This communication prepares the implementation of the KC in Feutap, including the creation of irrigation ponds for agriculture and small farm animals (e.g., goats and sheep). The view is promoted that Feutap is a potential viable space in which life and work are possible, using the existing rainfall and the few natural springs in a sustainable manner. The presented concept can be extended to other hilly small communities with similar hydraulic regimes.

Epidemiology of the Acceptance of Anti COVID-19 Vaccine in Urban and Rural Settings in Cameroon.

The COVID-19 pandemic rapidly evolved in December 2019 and to prevent its spread, effective vaccines were produced and made available to the population. Despite their availability so far in Cameroon, the vaccination coverage remains low. This study aimed at describing the epidemiology of the acceptance of vaccines against COVID-19 in some urban and rural areas of Cameroon. A cross-sectional, descriptive and analytical survey was conducted from March 2021 to August 2021 targeting unvaccinated individuals from urban and rural area. After receiving appropriate administrative authorizations and an ethical clearance from the Institutional Review Board (or Ethics Committee) of Douala University (N° 3070CEI-Udo/05/2022/M), a cluster sampling at many degrees was performed and a language-adapted questionnaire was completed by each consenting participant. Data were analyzed using Epi info version 7.2.2.6 software and for p-values < 0.05, the difference was considered as statistically significant. Out of 1053 individuals, 58.02% (611/1053) participants were residing in urban and 41.98% (442/1053) in rural areas. Good knowledge relative to COVID-19 was significantly higher in urban areas as compared to rural areas (97.55% vs. 85.07, p < 0.000). The proportion of respondents who intended to accept the anti COVID-19 vaccine was significantly higher in urban areas than rural areas (42.55% vs. 33.26, p = 0.0047). Conversely, the proportion of anti COVID-19 reluctant respondents thinking that the vaccine can induce a disease was significantly higher in rural areas than urban areas (54 (35.07 vs. 8.84, p < 0.0001). The significant determinants of anti-COVID-19 acceptance were the level of education (p = 0.0001) and profession in the rural areas (p ≤ 0.0001), and only the profession (p = 0.0046) in the urban areas. This study globally showed that anti-COVID-19 vaccination remains a major challenge in urban as well as rural areas in Cameroon. We should continue sensitizing and educating the population about vaccine importance in preventing the COVID-19 spread.

Experimental Analysis of Four Agricultural Biomass Fuel (Wood Charcoal, Maize Straws, Palm Kernel Sawdust and Rice Husks) Subjected to Fixed Bed Gasification Process

The production of syngas from gasification is a heathy way to convert agricultural residues into energy. In fact the gasification characteristics, konwn as the temperature and the plasma duration, were assessed. The gasification process consisted in introducing into a designed updraft gasifier four types of biomass (maize, rice husks, charcoal and kernel palm) of a well known quantity (2, 4, 6, 8, and 10 kgs). The biomass choice was done because of their abundance and they can assure the renewal of resources in an industrial project setting. Air used as a gasifying agent, was introduced in the gasifier through a control valve. Air supply in the gas producer to favor the biomass conversion was done using a fan of 12 Volts turned by photovoltaic solar panels of 100 W each. The main results of this study were as follows. Whatever the quantity of biomass used, the highest gasification temperature was recorded with the charcoal followed by the palm kernel. The plasma or flame duration was the highest during the gasification of 10 kgs of charcoal followed by the palm kernel. The palm kernel and the maize straws are more advisable for the gasification purpose in rural areas of Cameroon.

What Explains Differences in Early Child Development Between Urban and Rural Areas in Cameroun?

The objective of this paper is to identify factors that determine the difference in early child development between urban and rural areas of Cameroon. We have used the Fairlie (2005) decomposition method and the data collected as part of the 5th MICS survey conducted in Cameroon in 2014, which provides information for children aged 36 to 59 months. This database indicates that among these children, 68% of those living in urban area enjoy good early child development, against 56.5% of those living in rural area. This difference is significant at 1% threshold. Results of the global decomposition reveal that only 48% of this difference is due to difference in characteristics between the two areas, so can be explained, and 58% is non- explainable and not significant. Results of the detailed decomposition show that five factors contribute to the explanation of this explainable difference: ‘Having more than two learning books’ contributes to the explanation of 46.29% of it; ‘Following an educational program’ to the explanation of 43.69%; ‘Living in a household whose head comes from the Center, South and East regions of Cameroon’ to the explanation of 16.58%; ‘Carring out counting activities, spelling words and / or drawing with a parent or another adult’ to the explanation of 10.59% and ‘Living in an average living standard household’ to the explanation of 7.84%. We suggest government should give children of the two areas the same chance to access these factors.

What Explains Differences in Early Child Development Between Urban and Rural Areas in Cameroon?

Influence of socioeconomic factors on the nutritional status of pupils of 5 to 11 in rural areas in cameroon: Case of the Nyambaka municipality in the Adamawa region.

Malnutrition greatly increases the risk of infant mortality and vulnerability to various diseases later in the long run. It has been shown that children's malnutrition is the result of low household income. Rural areas in Cameroon are mainly made up of poor families. This guided the present research to analyze some socioeconomic factors and their impact on the nutritional status of pupils. Using a simple random sampling technique, 300 pupils were recruited. About 66.33% of pupils were from poor families. Obesity was more prevalent in the category of rich pupils (09.52%) compared to poor (06.53%). The height and weight of pupils studied were lower than the reference (P < 0.001). This study carried out in a single council is proven to be limited for a better understanding of the epidemiology of malnutrition among students, and large-scale studies would be adequate to better prevent and control malnutrition in rural areas.

Prevalence and factors associated with post-partum depression in a rural area of Cameroon: a cross-sectional study.

Introductionpost-partum depression is one of the many challenges associated with childbirth. In Cameroon, the focus is more on post-partum obstetric complications resulting in underdiagnosis and misdiagnosis of this condition. The current socio-political crisis plaguing the English-speaking part of Cameroon has increased the stressors that may inherently increase the prevalence. There is no published data describing post-partum depression in a rural setting in Cameroon. We seek to determine the prevalence and factors associated with PPD in women attending the Tubah District hospital, North West Region, Cameroon.Methodswe conducted a cross-sectional hospital-based study at the Tubah District Hospital. A consecutive convenience sampling technique was used to recruit participants. Our main outcome was post-partum depression which was assessed using the Edinburgh Post-partum Depression Scale.Resultsa total of 207 post-partum women took part in this study with a mean age of 27.54 ± 5.78 years. The prevalence of depression was 31.8%. Gender-based violence (OR: 4.67, P = 0.013), financial stress (OR: 3.57, P = 0.002) and male baby (OR: 2.83, P < 0.001) were independent psychosocial factors associated with PPD. Independent psycho-clinical factors of post-partum depression include family history of mental health illness (OR: 4.34, P = 0.04) and previous history of depression (OR: 4.17, P = 0.02).Conclusionthe prevalence of post-partum depression in women attending the Tubah District Hospital, Northwest Region, Cameroon is high. The factors associated with PPD are many. Identification of risk factors, early diagnosis and proper management can prevent PPD, disabling morbidity, and suicide in mothers.

Examination of the Cameroon DHS data to investigate how water access and sanitation services are related to diarrhea and nutrition among infants and toddlers in rural households.

Undernutrition among children is a significant issue in rural areas in Cameroon, with diarrhea being one of the major contributing risk factors. To gain a better understanding of the risk factors of diarrhea, the main objective of this epidemiological study was to examine associations between water access and sanitation service with diarrhea, diet diversity, and anemia among infants and toddlers in rural households in Cameroon. The study involved household- and individual-level data of 2,129 rural-dwelling infants and toddlers from the Demographic and Health Survey database. About one-third of infants and toddlers were experiencing diarrhea, with higher odds among those who lived in households with limited water service (p = 0.028). The odds of having diarrhea were 50% higher among infants and toddlers when households did not have sanitation facilities (p = 0.007). The lack of improved water and sanitation was also associated with a low intake of various food groups among older infants and toddlers. The prevalence of anemia was high, but no significant differences were seen by water and sanitation services. The achievement of SDG #6 will help address undernutrition and achieve other SDGs, including improving health and wellbeing.

Fluctuation in Coffee Production and Implications for Development in Noni Sub-Division

Coffee cultivation is one of the main economic activities which is carried out by most farmers in some rural areas in Cameroon and it is a major source of livelihood. Over the years, the prices of coffee in the world market have been descouraging. Using primary and secondary sources of data, focus group discussion, this study investigates coffee cultivation in the Noni Sub-Division from the 1990s to 2014. It also looks at the general trends in coffee production in the Noni Sub- Division from 1990 to 2014. The results reveal that the cultivation of coffee in the area has been strongly affected by the low prices of coffee in the world market as well as the liberalization of the coffee sector in Cameroon. The study equally revealed that the socio-economic development of Noni Sub-Division strongly depends on the cultivation of coffee though the development is often affected by the low prices of coffee. The formation of Cooperative Societies in lagging areas, the stabilization of prices by the government and training of farmers will go a long way in improving on the coffee sector in this region and Cameroon as a whole.

A Comparative Analysis of the Effects of Fertility on Women’s Employment in Urban and Rural Areas of Cameroon

This paper compares the effects of fertility on women’s employment in Urban and Rural areas of Cameroon using pulled data from the 1991, 1998, 2004, 2011 and 2018 Demographic Health Survey (DHS) for Cameroon. The Logistic Regression, Fairlie and Multivariate decomposition models were used for analyses. The logistics regression results showed that fertility has a positive and statistically significant effect on women’s employment in Cameroon. The fairlie decomposition results showed that fertility, primary education, being in the richer and richest wealth level, husband’s being in primary education, being a Muslim and husband being in agricultural-self-employment all significantly reduced the differences in women’s employment in urban and rural areas. On the other hand, secondary and tertiary educational level for husband and wife, poorer and middle-income wealth group, being a Catholic, husband’s working in the agricultural sector, marriage, age at first cohabitation and being resident in urban areas all significantly increased the differences between women’s employment in the urban and rural areas. The Multivariate decomposition results showed that the largest significant contributor to differences in women’s employment in urban and rural areas of Cameroon was fertility. Fertility significantly increased the differences in women’s employment in urban and rural zones by 19.2%. The promotion of women’s employment in the urban areas through the subsidization of day-care, services and the provision of start up capital is recommended.

Cataract surgery in surgical camps: outcomes in a rural area of Cameroon.

To assess the complications and visual outcomes of cataract surgery during an outreach eye camp in Cameroon in which two foreign ophthalmologists operate alongside a local one. This is a retrospective and comparative cohort study. The patients were consecutively assigned to three groups depending on the ophthalmologist who performed the cataract surgeries. All eyes underwent manual sutureless incision cataract surgery with posterior chamber intraocular lens (PCIOL) implantation under peribulbar anesthesia. Postoperative visits were scheduled for the first day, first week and second month after the procedures. Intra- and postoperative complications, best-corrected visual acuity and also refractive errors were assessed. A total of 263 eyes underwent cataract extraction with PCIOL implantation. The percentage of eyes in which two or more lines of corrected distance visual acuity decreased were 2.4%, 2.7% and 0% for groups A, B and C, respectively. The percentage of eyes with good visual outcome (uncorrected distance visual acuity UDVA > 20/60) were, respectively, 82.09%, 81.43% and 80.82% for the three groups. Similar results were found between the three groups regarding complications. Ocular hypertension, transient corneal edema and hyphema were the incidences registered at the first postoperative control performed 24h after surgery. The most common complication observed 2months after surgery was posterior capsular opacity (2.6%). High-volume cataract surgery in low- and middle-income countries may have good visual outcomes and a low rate of complications when the procedures are performed by either foreign or local ophthalmologists. A program of high-volume cataract surgery carried out in a rural environment with few resources can give good visual outcomes in the hands of both foreign and local experienced ophthalmologists.

Global dynamics of a model of hepatitis B virus infection in a sub-Saharan African rural area

We formulate and systematically study a deterministic compartmental model of Hepatitis B. This model has some important and novel features compared with the well-known basic model in the literature. Specifically, it takes into account the differential susceptibility that follows the vaccine formulation employing three-doses schedule. It points up the HbeAg status of carriers, their levels of viral replication, the fact that treatment being not curative is recommended only to a small proportion of chronic carriers, and finally the fact that only inactive carriers are able to recover from disease. The model has simple dynamical behavior which has a globally asymptotically stable disease-free equilibrium when the basic reproduction number [Formula: see text] and an endemic equilibrium when [Formula: see text]. By the use of Lyapunov functions, when it exists, we prove the global asymptotic stability of the endemic equilibrium under some conditions. Using data from Tokombere, a rural area in Cameroon, numerical simulations are performed. These numerical simulations first confirm analytical results, second they suggest that a policy based on treatment could not significantly impact the course of the infection. Third, they show as it is well known that vaccination is a very effective measure to control the infection. Furthermore, they show that neonatal vaccination influences more the course of infection than mass vaccination strategy. Nevertheless, they picture how much loss between consecutive doses of vaccine could be harmful. Finally, it is suggested that for a Sub-saharan African rural area, two-thirds of expected incidence of Hepatitis B virus infection and one third of expected prevalence of chronic carriers could be averted by 2030 if the birth dose vaccination becomes systematic and if mass vaccination rate increases to up 10%.
