Exploring existing malaria services and the feasibility of implementing community engagement approaches amongst conflict-affected communities in Cameroon: a qualitative study.

BACKGROUND: Cameroon is one of the countries with the highest burden of malaria. Since 2018, there has been an ongoing conflict in the country, which has reduced access to healthcare for populations in affected regions, and little is known about the impact on access to malaria services. The objective of this study was to understand the current situation regarding access to malaria services in Cameroon to inform the design of interventions to remove barriers and encourage the use of available services. METHODS: A qualitative research study was carried out to understand the barriers preventing communities accessing care, the uptake of community health worker (CHW) services, and to gather perceptions on community engagement approaches, to assess whether these could be an appropriate mechanism to encourage uptake of community health worker (CHW) services. Twenty-nine focus group discussions and 11 in-depth interviews were carried out between May and July 2021 in two regions of Cameroon, Southwest and Littoral. Focus group discussions were held with CHWs and community members and semi-structured, in-depth interviews were conducted with key stakeholders including regional government staff, council staff, community leaders and community-based organisations. The data were analysed thematically; open, descriptive coding was combined with exploration of pre-determined investigative areas. RESULTS: The study confirmed that access to healthcare has become increasingly challenging in conflict-affected areas. Although the Ministry of Health are providing CHWs to improve access, several barriers remain that limit uptake of these services including awareness, availability, cost, trust in competency, and supply of testing and treatment. This study found that communities were supportive of community engagement approaches, particularly the community dialogue approach. CONCLUSION: Communities in conflict-affected regions of Cameroon continue to have limited access to healthcare services, in part due to poor use of CHW services provided. Community engagement approaches can be an effective way to improve the awareness and use of CHWs. However, these approaches alone will not be sufficient to resolve all the challenges faced by conflict-affected communities when accessing health and malaria services. Additional interventions are needed to increase the availability of CHWs, improve the supply of diagnostic tests and treatments and to reduce the cost of treatment for all.

A formative cross-sectional study to assess caregiver's health-seeking behaviour and knowledge surrounding malaria, and understand the burden of malaria among children under-five in conflict-affected communities of Cameroon.

BACKGROUND: Malaria remains a major global health problem often worsened by political instability and armed conflict. The purpose of the study was to explore community knowledge, attitudes and practices on malaria prevention, and to understand the burden of malaria and health-seeking behaviours of caregivers of children under-five in conflict-affected communities of the South West and Littoral Regions of Cameroon. METHODS: A cross-sectional survey involving internally displaced persons (IDPS), host population, and their children under-five was conducted across 80 communities. The survey was conducted from May to June 2021. Participants were interviewed using a structured questionnaire. Malaria prevalence for children under-five was determined using rapid diagnostic tests (RDT) on blood samples. Association between variables and displacement status was measured using chi square test and multivariate logistic regression model was fitted to identify factors associated with adequate knowledge on malaria prevention. RESULTS: A total of 2386 adults participated in the study and 1543 RDTs were conducted for children under-five. Adequate levels of knowledge and attitudes on malaria prevention was recorded among 1258 (52.9%) of the participants, with very strong evidence to suggest the level to be higher among the host (59.5%) compared to the IDPs (49.5%) and returnees (39.7%) (p < 0.001). Good practices towards malaria prevention was 43.3%, with very strong evidence indicating lower levels among IDPs (42.8%) and returnees (28.5%) compared to the host (49.4%) (p < 0.001). Malaria prevalence for children under-five was 54.0% and adequate health-seeking for suspected episodes of malaria was 53.0%, without any difference among IDPs (51.78%) and returnees (48.7%) compared to host populations (55.4%) (p = 0.154). Multivariate logistic regression model showed that there was quite strong evidence to suggest primary and secondary levels of education have higher odds of having correct knowledge of malaria prevention (adjusted odds ratio (AOR) 1.71, 95% confidence interval (CI): 1.11-2.64, p = 0.015 and AOR 1.80, 95% CI 1.15-2.82, p = 0.010 respectively). There was very strong evidence to suggest that owning a radio or a television was associated with greater odds of having a higher knowledge on malaria prevention (AOR 1.49, 95% CI 1.233-1.81, p = 0.000 and AOR 1.47, 95% CI 1.18-1.84, p = 0.001). CONCLUSION: Over half of the population have correct knowledge and attitudes towards malaria prevention but gaps in complete knowledge remained. Some of the caregivers know the correct malaria preventive practices coupled with largely unsatisfactory treatment approaches and reflected by the high prevalence of malaria among their children. In order to effectively treat malaria, innovative strategies should target community participation.

Effectiveness of Linkage to Care and Prevention Interventions Following HIV Self-Testing: A Global Systematic Review and Meta-analysis.

Over 38.4 million people were living with HIV globally in 2021. The HIV continuum includes HIV testing, diagnosis, linkage to combined antiretroviral therapy (cART), and retention in care. An important innovation in the HIV care continuum is HIV self-testing. There is a paucity of evidence regarding the effectiveness of interventions aimed at linking self-testers to care and prevention, including pre-exposure prophylaxis (PrEP). To bridge this gap, we carried out a global systematic review and meta-analysis to ascertain the effectiveness of interventions post-HIV self-testing regarding: (1) linkage to care or ART, (2) linkage to PrEP, and (3) the impact of HIV self-test (HIVST) interventions on sexual behaviors. We searched PubMed, Web of Science, SCOPUS, Cochrane Library, CINAHL Plus (EBSCO), MEDLINE (Ovid), Google Scholar, and ResearchGate. We included only published randomized controlled trials (RCTs) and quasi-experiment that compared HIVST to the standard of care (SoC). Studies with sufficient data were aggregated using meta-analysis on RevMan 5.4 at a 95% confidence interval. Cochrane's Q test was used to assess heterogeneity between the studies, while Higgins and Thompson's I2 was used to quantify heterogeneity. Subgroup analyses were conducted to identify the source of heterogeneity. Of the 2669 articles obtained from the databases, only 15 studies were eligible for this review, and eight were included in the final meta-analysis. Overall, linkage to care was similar between the HIVST arm and SoC (effect size: 0.92 [0.45-1.86]; I2: 51%; p: 0.04). In the population subgroup analysis, female sex workers (FSWs) in the HIVST arm were significantly linked to care compared to the SoC arm (effect size: 0.53 [0.30-0.94]; I2: 0%; p: 0.41). HIVST interventions did not significantly improve ART initiation in the HIVST arm compared to the SoC arm (effect size: 0.90 [0.45-1.79]; I2: 74%; p: < 0.001). We found that more male partners of women living with HIV in the SoC arm initiated PrEP compared to partners in the HIVST arm. The meta-analysis showed no difference between the HIVST and SoC arm regarding the number of clients (effect size: - 0.66 [1.35-0.02]; I2: 64%; p: 0.09) and non-clients FSWs see per night (effect size: - 1.45 [- 1.45 to 1.38]; I2: 93%; p: < 0.001). HIVST did not reduce the use of condoms during insertive or receptive condomless anal intercourse among MSM. HIVST does not improve linkage to care in the general population but does among FSWs. HIVST intervention does not improve linkage to ART nor significantly stimulate healthy sexual behaviors among priority groups. The only RCT that linked HIVST to PrEP found that PrEP uptake was higher among partners of women living with HIV in the SoC arm than in the HIVST arm. More RCTs among priority groups are needed, and the influence of HIVST on PrEP uptake should be further investigated.

Political instability and hiv/aids response in the south west and north west regions of Cameroon: a qualitative study.

BACKGROUND: Politically motivated violence and insecurity continue to be a major threat to progress in HIV epidemic control and a significant contributor to health inequality. Despite a decreasing HIV/AIDS disease burden, the Republic of Cameroon in West Africa is experiencing ongoing political instability in her North and South West Regions. Our study used qualitative methods to better understand key frontline health care providers' (fHCP) perceptions of the effects of political instability on HIV/AIDS response gains in Cameroon since 2018, as well as lessons learned for overcoming them. METHODS: Between July and August 2022, semi-structured, in-depth key informant interviews involving 10 purposively selected participants were conducted in the two regions. Interviews were recorded and transcribed verbatim, coded thematically, and analyzed manually. RESULTS: Six overarching themes emerged from the transcribed key informant interviews. They were as follows: Challenge with access to and availability of health care services (HIV care, commodity supply chain) in the smaller communities; Impact on continuity of treatment; Increased risk of new HIV infections; The socioeconomic impact of the crisis on the quality of life; The impact of the crisis on fHCPs' physical and mental health and the health system'; and Coping mechanisms. CONCLUSIONS: Frontline healthcare workers have acknowledged the significant impact the current political instability has had in hindering the development and advancement of a successful local response to HIV/AIDS in the two impacted regions of Cameroon. Coordinated efforts must be made to strengthen the health sector in areas such as HIV healthcare decentralization, supply chain, and protecting frontline healthcare workers from political quagmires in order to lessen the impact of the nation's socio-political crisis on the HIV/AIDS response and, more generally, on the entire health sector.

Loss to follow-up and associated maternal factors among HIV-exposed infants at the Mbarara Regional Referral Hospital, Uganda: a retrospective study.

BACKGROUND: Loss to follow-up (LTFU) deprives HIV-exposed infants the lifesaving care required and results in exposing HIV free infants to virus requisition risk. We aimed to determine the rate of LTFU, postnatal mother-to-child HIV-transmission (MTCT) and to identify maternal factors associated with LTFU among HIV-exposed infants enrolled at Mbarara Regional Referral Hospital PMTCT clinic. METHODS: Study participants were infants born to HIV-positive mothers enrolled in the PMTCT clinic for HIV care at Mbarara Regional Referral Hospital. While access database in the Early Infant Diagnosis (EID) clinic provided data on infants, the open medical record system database at the ISS clinic provided that for mothers. Infants were classified as LTFU if they had not completed their follow-up schedule by 18 months of age. At 18 months, an infant is expected to receive a rapid diagnostic test before being discharged from the PMTCT clinic. Postnatal MTCT of HIV was calculated as a proportion of infants followed and tested from birth to 18 months of age. Logistic regression was used to determine possible associations between mothers' characteristics and LTFU. In-depth interviews of mothers of LTFU infants and health workers who attend to the HIV-exposed infants were carried out to identify factors not captured in the electronic database. RESULTS: Out of 1624 infants enrolled at the clinic, 533 (33%) were dropped for lack of mother's clinic identification number, 18 (1.1%) were either dead or transferred out. Out of 1073 infants analysed, 515 (48%) were LTFU by 18 months of age while out of the 558 who completed their follow-up schedule, 20 (3.6%) tested positive for HIV. Young age of mother, far distance to hospital and non-use of family planning were identified as outstanding factors responsible for LTFU. In addition, in-depth interviews revealed facility-level factors such as "waiting time" which would not be found in routine client databases. CONCLUSION: This study has revealed a high rate of loss to follow up among HIV-exposed infants enrolled at Mbarara Regional Referral hospital PMTCT clinic. Young maternal age, long distance to health facility and failure to use family planning were significantly associated with LTFU. Incorporating family planning services in the ART and PMTCT clinics could reduce loss to follow-up of HIV exposed infants. Young mothers should be targeted with information on the importance of completing the EID follow-up schedule and also, their clinic identification number be gotten at each visit.

Malaria in patients with sickle cell anaemia: burden, risk factors and outcome at the Laquintinie hospital, Cameroon.

BACKGROUND: It is believed that the current prevalence of malaria in endemic areas reflects selection for the carrier form of sickle cell trait through a survival advantage. Malaria has been incriminated as a great cause of mortality in people with sickle cell disease (SCD). However, people with SCD, a high-risk group, do not benefit from free or subsisized malaria prevention and treatment in Cameroon unlike other vulnerable groups which may be due to insufficient evidence to guide policy makers. This study aimed at describing clinical and socio-demographic characteristics of patients with malaria, determining the prevalence of malaria in hospitalized children and in those with SCD and without, compare frequency of presentation of malaria related complications (using clinical and laboratory elements that define severe malaria) between children admitted for malaria with SCD and those without and finally, determing the risk factors for death in children admitted for malaria. METHODS: This was a retrospective analysis of admission records of children age 1 to 18 years with a confirmed malaria diagnosis admitted at the Laquintinie Hospital during January 2015 through December 2018. Clinical features, laboratory characteristics and outcome of malarial infections, stratified by SCD status were studied. Patients with HIV infection, malnutrition, renal failure and discharged against medical advice were excluded from the study. Data were analysed using Epi-info 7 software and analysis done. Chi square test, Odds ratios, CI and student's t test were used to determine association between variables. Statistical significance was set at p-value ≤0.05. RESULTS: The prevalence of malaria was lower among children with SCD than it was among children without SCD (23.5% vs 44.9%). Similarly, among those with a positive microscopy, the mean parasite density was significantly lower among children with SCD than it was among children without SCD (22,875.6 vs 57,053.6 parasites/ µl with t-value - 3.2, p-value 0.002). The mean hemoglobin concentration was lower in SCD as compared to non SCD (5.7 g/l vs 7.4 g/l, t-value - 12.5, p-value < 0.001). Overall mortality in SCD was 3.4% and malaria was reponsible for 20.4% of these deaths as compared to the 35.4% in non SCD patients. Convulsion and impaired consciousness were significantly lower in SCD group (OR:0.1, CI: 0.1-0.3, p value < 0.01 and OR:0.1, CI:0.1-0.2, p-value < 0.001 respectively). Death was significantly higher in SCD patients with malaria as compared to SCD patients admitted for other pathologies (3.2% vs 1.5%., OR:2.2, CI:1-5, p-value 0.050). CONCLUSION: The SCD population has a lower mortality related to malaria compared to the non-SCD population. Meanwhile, within the SCD population, those admitted with malaria are twice more likely to die than those admitted for other pathologies. Jaundice, hepatomegaly and splenomegaly were common in SCD with malaria, however no risk factors for malaria severity or malaria related death was identified.

Awareness and practice of birth preparedness and complication readiness among pregnant women in the Bamenda Health District, Cameroon.

BACKGROUND: Birth preparedness and complication readiness has as goal to reduce maternal and neonatal mortality. This concept developed by the organizations of the United Nations permits pregnant women and their families seek health care without delay in case of obstetric complications and delivery. Though its benefits have been proven in several countries, little is known of this in Cameroon and specifically in the North West Region. Therefore, the intention of the study was to assess the awareness and practice of birth preparedness and complication readiness in this health district. METHODS: This was a facility-based cross sectional study carried out in the Bamenda health district of the North West Region, Cameroon. Three hundred forty-five pregnant women of ≥32 weeks gestational age seen at the antenatal consultation units were recruited. The dependent variable was birth preparedness and complication readiness while the independent variables were the socio-demographic and reproductive health characteristics. Data collected was analyzed with SPSS and Microsoft excel. Frequency distributions were used to determine the awareness and practice of birth preparedness and complication readiness. RESULTS: Of the 345 pregnant women included in this study, 159(46.1%) were aware of birth preparedness and complication readiness. The practice of birth preparedness and complication readiness was unsatisfactory as only 65(18.8%) were considered prepared. CONCLUSION: Education and counselling on birth preparedness and complication readiness is not made available to the pregnant women resulting in poor knowledge. Thus, reflected in the low practice of preparation for birth and its complication observed.

Prevalence and risk factors associated with cryptosporidiosis among children within the ages 0-5 years attending the Limbe regional hospital, southwest region, Cameroon.

BACKGROUND: Cryptosporidiosis is a pathological condition caused by infection with coccidian protozoan parasites Cryptosporidium. Cryptosporidium is one of the most common causes of childhood diarrhea in developing countries. So far, no data has been published on its prevalence among children with diarrhea in Cameroon. This study was therefore, designed to assess the prevalence and risk factors associated with Cryptosporidiosis among children within the ages 0-5 years suffering from diarrhea and being attended to at the Limbe Regional Hospital. METHODS: The study was a hospital based analytical cross-sectional study involving children within the ages 0-5 years (n = 112) hospitalized or consulted in the pediatric departments of the hospital between April 2018 and May 2018. Stool specimens were processed using the modified acid-fast staining method, and microscopically examined for Cryptosporidium infection. RESULTS: A total of 112 participants were recruited out of which 67 presented with diarrhea. A high prevalence 9/67 (13.40%) of Cryptosporidium was noticed in children with diarrhea than children without diarrhea 1/45 (2.2%). There was a significant relationship (p = 0.041) between prevalence of Cryptosporidium and the presence of diarrhea in children within the ages 0-5 years in the Limbe Regional Hospital. It was realized that children from parents with primary level of education, children whose parents did not respect exclusive breastfeeding and those whose parents were giving them pipe borne water for drinking recorded a higher prevalence. CONCLUSIONS: This study revealed an overall prevalence of 8.9% for Cryptosporidium among children of ages 0-5 years that attended the Limbe Regional Hospital. The prevalence among children that presented with diarrhea was 13.4%. The study clearly demonstrated that Cryptosporidium is an important protozoal etiologic agent for children with diarrhea in Limbe.

Prevalence, Epidemiological, and Clinical Profile of Patients Coinfected with Human Immunodeficiency Virus and Tuberculosis in the Coronavirus Disease 2019 Context in Health Facilities in the East Region, Cameroon.

Background and Objective: Suspected cases of tuberculosis (TB) are identified for confirmation by bacteriological tests through clinical screening for TB in people living with human immunodeficiency virus (HIV) during routine visits or when antiretrovirals (ARVs) are dispensed. Our aim is to determine the prevalence and describe the epidemiological and clinical characteristics of HIV-TB coinfected patients in the coronavirus disease 2019 (COVID-19) setting in health facilities in the East Region of Cameroon. This study addresses knowledge gaps on HIV-TB coinfection during COVID-19, aiming to provide insights into the interaction and impact of HIV, TB, and COVID-19 on individuals' health. Methods: This was an observational study. It involved two retrospective cohorts of HIV-TB coinfected patients before and after the COVID-19 pandemic. We conducted manual reviews of the medical records and antiretroviral therapy (ART) and TB registers of 262 patients. These patients were coinfected with HIV and TB during the period from April 2019 to April 2021 in 11 health facilities in the East Cameroon health region. The sociodemographic and clinical characteristics of the cases were extracted from the consultation registers and entered into the KoBo Collect application, then analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 25. Results: In this study of 262 HIV-TB coinfection cases, 60.3% occurred before COVID-19, and 39.7% during the pandemic. HIV-TB coinfection prevalence among HIV patients was 1%. Patients averaged 39.3 years in age, with a significant shift in sex ratios from 0.65 to 1.33 between pre-COVID-19 and COVID-19 cohorts. Education varied, with 45.8% having secondary education, 44.8% with primary, 2.4% having higher education, and 7.1% having none. Most (78.9%) had professional occupations, and 53.7% lived in rural areas. The majority were newly diagnosed (96.3% before COVID-19; 93.3% during COVID-19), with 3.7% relapses and 4.2% discontinuing treatment. Most had pulmonary TB (84.9%) and were aware of treatment duration (94.6%). About 65.4% experienced treatment-related adverse events. Regarding family support, 69.3% received help with medication. However, the concern was 80.6% did not adhere to anti-COVID-19 measures. Conclusion and Global Health Implications: Gender was significantly associated with compliance. Most patients were on treatment, but a small percentage had discontinued it. Patients need to be made aware of the importance of complying with anti-COVID-19 barrier measures to prevent a potential worsening of the health situation. Moreover, clinical and biological monitoring needs to be stepped up throughout the course of anti-TB treatment.

The SPIN framework to control and prevent the Marburg virus disease outbreak in Equatorial Guinea.

A full grasp of the epidemiological factors promoting transmission is necessary for responding to highly infectious diseases, which involves their control and prevention. With the recent outbreak of Marburg Virus Disease (MVD) in Equatorial Guinea, we saw the need to re-shed some technical light based on our field experiences and published literature. We reviewed 15 previous MVD outbreaks globally. Coupled with core One-Health approaches, we highlighted the SPIN (socio-environmental context, possible transmission routes, informing and guiding public health action, needs in terms of control measures) framework as a guiding tool for response teams to appropriately approach this highly contagious infectious disease outbreak for collective and stronger global health security. The Central African Regional Collaborating Centre (RCC) of the Africa Centres for Disease Control and Prevention (Africa CDC) has a big lead role to play, most especially in coordinating the community engagement and risk communication packages of the response, which is highly needed at this point. We reiterate that this framework remains relevant, if not timely, in rethinking pandemic preparedness and response in resource-limited settings.

Socio-economic predictors of uptake of malaria interventions among pregnant women and mothers of under 5 children in Oyo State, Nigeria: a cross-sectional study.

Introduction: socio-economic status (SES), especially for women, influence access to care. This study aimed to determine the relationship between SES and uptake of malaria intervention by pregnant women and non-pregnant mothers of children under 5 years old in Ibadan, Oyo state, Nigeria. Methods: this cross-sectional study was conducted at Adeoyo teaching hospital located in Ibadan, Nigeria. The hospital-based study population included consenting mothers. Data were collected using an interviewer-administered modified validated demographic health survey questionnaire. The statistical analysis involved both descriptive (mean, count, frequency) and inferential statistics (Chi-square, logistic regression). Level of statistical significance was set at 0.05. Results: mean age of the study´s total of 1373 respondents was 29 years (SD: 5.2). Of these, 60% (818) were pregnant. The non-pregnant mothers of children under five years old showed a significantly increased odds (OR: 7.55, 95% CI: 3.81, 14.93) for the uptake of malaria intervention. Within the low SES category, women aged 35 years and above were significantly less likely to utilize malaria intervention (OR=0.08; 95% CI: 0.01-0.46; p=0.005) compared to those younger. In the middle SES, women who have one or two children were 3.51 times more likely than women with three or more children to utilize malaria intervention (OR=3.51; 95% CI: 1.67-7.37; p=0.001). Conclusion: the findings provide evidence that age, maternal grouping, and parity within the SES category can significantly impact on uptake of malaria interventions. There is a need for strategies to boost the SES of women because they play significant roles in the wellbeing of members of the home.

Malaria Elimination: What Can Africa Learn from China?

For decades now, malaria has been an important public health concern in Africa, which bears the greatest burden for the disease, affecting children and adults alike. Although a few countries (Australia, Brunei, Singapore, and Algeria, among others) have previously eliminated malaria, the World Health Organization (WHO), on June 30, 2021, declared China malaria-free. This commentary seeks to explore what China did differently to eliminate malaria and what Africa can learn from China's experience. First, Africa can use innovative tools and strategies used by China to attain success. Second, Africa can create a multi-sector collaboration among Heads of States in high burden malaria-affected countries by involving all stakeholders such as ministries of health, finance, research, education, development, public security, the army, police, commerce, industry, and information technology, customs, media and tourism to jointly fight malaria in all African countries. Furthermore, African countries could adapt the genetics-based approaches used by China in the elimination of mosquito breeding grounds. Finally, Africa can also adapt a better surveillance system of reporting on malaria daily as China did in their experience.

Barriers towards the Prevention and Treatment of Malaria among Pregnant Women at the Nkwen Health Center Bamenda, Cameroon.

Malaria remains an important public health problem such that, assessing the challenges experienced among pregnant women (vulnerable) with the uptake of malaria prevention methods and treatment is pertinent. This hospital-based cross-sectional descriptive study that was carried out at a Medicalized Health Center in Nkwen, Cameroon, sought to assess the barriers to malaria prevention faced by 51 pregnant women who attended antenatal clinic (ANC). Over 88% of participants were 15-30 years old. All participants knew at least one symptom of malaria, with 20% of them confirmed to have taken intermittent preventive treatment in pregnancy (IPTp) and 53% reported using insecticide-treated bed net (ITN). Educating pregnant women and their spouses on the uptake of IPTp and the use of ITN is a key strategy to curb its high malaria morbidity and mortality rates.

A case report of ruptured ectopic pregnancy plus massive hemoperitoneum on a heterotrophic pregnancy in a resource-poor setting, Mbengwi, Cameroon.

Heterotopic pregnancy is a rare obstetrics phenomenon and carries significant maternal morbidity and mortality due to the risk of rupture of the ectopic pregnancy. Physicians tend to feel comfortable and relieved when an intrauterine gestation sac is seen. This results in an inadequate inspection of the adnexae and remaining structures during emergency bedside ultrasound despite a strong initial clinical suspicion of ectopic pregnancy. We present a case report of ruptured ectopic pregnancy and massive hemoperitoneum in a patient with heterotopic pregnancy. The diagnosis was done on bedside ultrasonography in a clinically unstable 32-year-old patient with a history of infertility. She presented with acute abdominal pain, body weakness, and amenorrhea. She underwent emergency laparotomy and salpingectomy. In our context where ultrasound is not readily available, practitioners carrying out salpingectomy for ruptured ectopic pregnancies should bear in mind the plausibleness of heterotopic pregnancy to properly handle the uterus.

Marburg virus disease outbreak in Guinea: a SPIN framework of its transmission and control measures for an exemplary response pattern in West Africa.

Responding to highly infectious diseases relies on a thorough understanding of transmission epidemiology. With the recent outbreak of Marburg Virus Disease (MVD) in Guinea, we saw the need to shed some technical light based on published literature and our field experiences. We reviewed 14 previous MVD outbreaks globally. Coupled with core one - health approaches, we propose a Socio-environmental context, Possible transmission routes, Informing and guiding public health action, Needs in terms of control measures (SPIN) framework as a guiding tool for response teams to appropriately approach future infectious disease outbreaks.

Use of Trained Non-Medical Staff to Improve Access to HIV Testing Services in Africa: Implementation of the World Health Organization Opt-out Approach in Cameroon.

BACKGROUND: The Joint United Nations Programme on HIV/AIDS (UNAIDS) in 2019 estimated that 450,000 to 50,000 people in Cameroon were living with HIV, yet only 79% knew their HIV status which is far from the 90% target for 2020. To address this situation, Cameroon adopted the "Opt-out" strategy of the World Health Organization (WHO) and use of trained non-medical cadre (psychosocial agents) to reach out to more people with HIV testing services (HTS). This describes the implementation and outcomes of this strategy by reviewing the activity of a typical day in the Yaoundé Central Hospital (YCH) in Cameroon. METHODS: HTS were offered to hospitalized and ambulatory patients (including their companions) in different departments of the YCH. Following screening for recent HIV testing, those with unknown HIV status that gave consent or did not explicitly refuse testing (as per the "Opt-out Strategy"), were counseled and tested for HIV. Testing followed the "National HIV Rapid Testing Algorithm" using rapid diagnostic test kits. Results were either positive, negative or indeterminate. Patients with positive HIV results were linked to the Care and Treatment Center for treatment initiation. RESULTS: Of the 350 patients screened and offered HTS using non-medical cadre (psychosocial agents), 193 (55.1%) were hospitalized and 157 (44.9%) came for outpatient visits. The age of participants ranged from 14 to 92 years and the yield of HIV testing in the sample population was 5.1% (6.2% for hospitalized patients and 3.8% for outpatient clinics). Statistics revealed that five HIV-positive patients had never been offered HTS before the study. The study revealed that HTS acceptance rate among hospitalized patients was 69.6% and that all new positive patients started antiretroviral treatment on the same day. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: It is feasible to use trained non-medical staff for HIV testing services (HTS). Task-shifting by using trained psychosocial agents can help in case identification and linkage to HIV treatment services.

Acceptability of COVID-19 Vaccine in Africa.

As Africa prepares to overcome the difficult challenges of COVID-19 vaccination roll-outs, a number of factors, including equitable access, effective and efficient sufficient supply chains, a scope of established determinants will need to be considered in order to enhance vaccine acceptability and uptake. In this commentary, we present six major determinants of vaccine acceptability and uptake in Africa. We summarize these determinants with the acronym VAMRIS: V= Vaccine hesitancy; A= Attitude and uptake by health care workers; M= Misinformation; R= Religion; I= Immunization roll out plans; S= Social influences and enabling environment. Understanding determinants of COVID-19 vaccine acceptability will guide public health officials make informed decisions. As the Vaccine becomes progressively available, strategies for efficient roll-out to achieve massive uptake by the targeted population will depend on a number of factors. These include: community engagement efforts; types of health promotion activities and/or messages; community sensitization to dispel myths and misconceptions; endorsements and buy-ins from local champions, celebrities, authorities; logistic considerations; and incentives to health counsellors/workers to create demand.

Non-SHEF2 Model related containment and control measures against COVID-19 in Africa.

COVID-19 Pandemic has the potential to overwhelm the underserved health care systems of African countries characterized by inadequate infrastructure and too few medical personnel. In responding to the COVID-19 Pandemic, many African countries are using a combination of containment and mitigation activities but in this commentary, we focus on what we term the Non-SHEF2 (S: Social distancing, H: Hands, E: Elbows, F: Face, F: Feel) model related control and containment measures which include seven key measures against COVID-19 doped 'TITHQC2' namely, T: Travel-related measures, I: Information and guidance, T: Treatment; H: Hospital containment measures; Q: Quarantine, C: Community containment measures, C: Case detection and contact tracing. COVID-19 is a reality and demands rapid and decisive action to be taken.

Comparative study of clinical methods versus ultrasound methods for accurate gestational age determination in different trimesters of pregnancy, Ndop District Hospital, North West region, Cameroon.

INTRODUCTION: gestational age is the estimated age of gestation from a fetus during its development and this is very important for the mother who wants to know when to expect the birth of her baby and for the health care provider so they can chose the time at which to perform various assessment. However, from the information outlined in this research, it can be seen that last menstrual period (LMP) and follicle-stimulating hormone (FSH) are used to assess gestational age. While GSD, CRL, BPD, HC, AC and FL are biometric parameters that can be measured on a fetus in order to estimate gestational age. Many clinicians and ultrasonologists feel that if they are unable to obtain an accurate measurement at the time, they have sometimes failed to do an adequate job. METHODS: the study was a comparative study on clinical method versus ultrasound method for accurate gestational age determination and also to determine the significance of fetal biometric parameter in GA determination. The study was an observational, cross sectional and participatory study for a period of 5 weeks from the 22nd of January to the 22nd of February 2018. A total of 72(74.2%) ANC cases were sampled during ultrasonography. Gestational ages from their clinic card were recorded. Twenty five questionnaires were given out to 25(26.8%) health care personnel to assess clinical method. Data was analyzed using SPSS version 16 plus and Microsoft Excel 2010. RESULTS: results showed the best clinical method used was LMP with 9(36%) but when compared to ultrasound, ultrasound presented with greater accuracy of 15(60%) and clinical method 10(40%). CONCLUSION: based on the findings, it could be concluded that compared to the physical examination and clinical methods, ultrasound examination of the fetus provided the physician and health care professionals with greater accuracy for gestational age.

Retention in HIV/AIDS Management Services: is it Really Poor? The Case of Yaounde Central Hospital in Cameroon.

BACKGROUND: After consecutively defaulting on their appointments for three months, many HIV positive patients are often reported to have defaulted on their treatment, become lost to follow-up (LTFU), or no longer in care. We sought to determine if retention in HIV/AIDS care and treatment is really poor. METHODS: Outcomes of patients with missed clinic appointments and reasons for missing appointments were studied. We sampled adult HIV positive patients on antiretroviral therapy (ART) who by clinic had missed their clinic appointments by more than four weeks between 1997 and 2019 at the HIV Care and Treatment Center (CTC) (Day Hospital) of the Yaoundé Central Hospital. We assumed that patients who missed their clinic appointment also missed some doses of their ART medications. Patients considered LTFU and those who had defaulted for two months were traced by telephone calls and home visits. Reasons for ART discontinuation were recorded for those who stopped or interrupted ART. RESULTS: Of the 1139 patients who were either LTFU or who had defaulted for two months, 247/1139 (22 %) could not be traced. Out of the successfully traced patients, 50 (4%) had died and 798/1139 (70%) were alive and 310/1139 (27%) were on ART of which 35/1139 (3%) had developed informal ways of obtaining ART through clinic personnel. A good number were brought back to and reinitiated on ART after tracking (540/1139 or 47%). Of those known not to be on treatment(ART), 27/1139 (2%) had deliberately stopped ART and 63/1139 (6%) promised to return and took an appointment with CTC pyscho-social workers. Major reasons shared for missing clinic appointments were travel out of city (39%), distance from health facility, and financial cost for getting to health facility. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: Despite clinic data showing many patients had missed monthly appointments or were LTFU, we saw that a sizeable amount of such patients were actually in care and on ART. The above findings lead to the suggestion that clinic data used in program performance evaluation may not always reflect the true picture retention in care for persons in HIV/AIDS programs at hospital and national levels.
