The effect of the ongoing civil strife on key immunisation outcomes in the North West and South West regions of Cameroon

Malaria vaccine acceptance and associated factors in cameroon: A nationwide cross-sectional survey

INTRODUCTION

Malaria is a life-threatening mosquito-borne disease. This significant public health problem disproportionately affects people in Africa. Despite investments in existing vector control and curative treatments, malaria remains the first infant-child morbidity and mortality cause, with 11,000 annual deaths in Cameroon. However, there are effective vaccines against the disease. So, this study sought to evaluate vaccine acceptance and related factors to guide the vaccine rollout.

METHOD

This nationwide cross-sectional survey collected data from December 2023 to January 2024 using an online and in-person questionnaire. The chi-square test identified the malaria vaccine acceptance elements, and multiple logistic regression depicted factors linked to vaccine acceptance. SPSS enabled analysis, and a p-value <0.05 was considered significant. Microsoft Excel 365 eased the elaboration of charts and tables.

RESULT

Data from 2025 participants indicated a 91 % malaria vaccine acceptance. This rate varied from 78 % in the Littoral to 94 % in the Far North and South West regions. Factors that favor vaccine acceptance include a history of severe malaria (OR = 1.4, 95 %CI: 1.0-1.8, p = 0.03), awareness of the availability of the malaria vaccine for infants (OR = 1.4, 95 %CI: 1.0-2.0, p = 0.03), and working in the vaccination service (OR = 3.8, 95 %CI: 2.7-5.3, p < 0.01). Elements reported for vaccine hesitancy include fear of unsafe and negative rumors about the vaccine.

CONCLUSION

People in Cameroon are willing to get their children vaccinated against malaria. However, following regional acceptance disparities and identified hesitancy points, it is crucial to reinforce communication to address population groups, doubts, and rumors about vaccines to ensure optimal uptake in the country's regions during the malaria vaccine rollout.

COVID- 19 vaccine uptake and its determinants in Cameroon: a systematic review and meta-analysis (2021-2024)

BACKGROUND

COVID-19 vaccination is crucial for mitigating the pandemic's impact. However, vaccine hesitancy and access challenges have hindered global vaccination efforts. This meta-analysis aimed to estimate the pooled COVID-19 vaccine uptake proportion and identify associated determinants in Cameroon.

METHODS

This review, conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, identified articles through searches of electronic databases, including PubMed, ScienceDirect, and Google Scholar, as well as through gray literature. The search encompassed published and unpublished studies from 2021 to 2024 reporting on COVID-19 vaccine uptake and/or acceptance in Cameroon. Extracted data were compiled in a Microsoft Excel spreadsheet and analyzed using R statistical software (version 4.4.2). A random-effects model was employed when heterogeneity exceeded 50%. Publication bias was assessed using funnel plots, Egger's and Begg's tests. Meta-regression was used to explore the influence of study characteristics.

RESULTS

Twenty-two studies, encompassing 24,130 participants, were included. The pooled vaccine uptake proportion was 37.14% (95% CI: 29.24-45.05) with substantial heterogeneity (I2 = 98.2%, p < 0.001). Subgroup analyses revealed lower uptake among the general population (23.18%; 95% CI: 10.11-36.25) and in community settings (16.0%; 95% CI: 0.97-31.04) compared with healthcare workers (42.12%; 95% CI: 34.14-50.09). Younger age (OR = 0.53; 95% CI: 0.42-0.67) was inversely associated with vaccine uptake, while being in a partnership (OR = 1.59; 95% CI: 1.11-2.27) was positively associated. Higher levels of education (OR = 1.75; 95% CI: 1.56-1.97), urban residence (OR = 1.66; 95% CI: 1.21-2.29) were positively associated with vaccine acceptance.

CONCLUSION

This meta-analysis revealed a suboptimal pooled COVID-19 vaccine uptake required to ensure a herd immunity. The results of this meta-analysis underline the crucial need to step up efforts to improve vaccination coverage, particularly among the most vulnerable populations. Identifying and addressing the factors underlying this low coverage is imperative if public health objectives are to be met. Public health interventions should be tailored to address the specific concerns and needs of different age groups and marital statuses.

Prevalence of Depression Among People Living with HIV on Antiretroviral Therapy in Africa: A Systematic Review and Meta-Analysis

BACKGROUND

HIV is a global health issue, with the highest number of infected individuals found in sub-Saharan Africa. The coexistence of HIV with depression is a huge challenge. This study aimed to investigate the prevalence of depression in people living with HIV (PLWHIV) who are on antiretroviral therapy (ART) in Africa.

METHOD

PubMed, Scopus, and bibliographic screening were used to identify suitable literature. The study adhered to guidelines outlined by Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The Newcastle-Ottawa guideline was used to assess the quality of the included cross-sectional studies. Subgroup analysis and meta-regression were subsequently conducted following the meta-analyses, based on heterogeneity. A meta-analysis software online tool and Jamovi software (version 2.4.8.0) were used to analyse the data, and the results were presented as prevalence and 95% confidence intervals.

RESULTS

Thirty-four cross-sectional studies identified from the databases were deemed relevant. The overall sample size was 21,143 PLWHIV on ART in African countries. The analysed data showed the prevalence of depression to be 36%, with 95% CI (27% to 40%), p < 0.01, in Africa. However, the subgroup showed that the highest prevalence was in Northern Africa, with a prevalence of 41% with 95% CI (20% to 50%), p < 0.01, followed by those in Southern and Eastern Africa, with a prevalence of 38% with 95% CI (27% to 49%) and 39% with 95% CI (26% to 50%), p < 0.01, respectively. The lowest prevalence was observed in Western Africa, with a prevalence of 20% with 95% CI (14% to 27%), p < 0.01.

CONCLUSIONS

Our findings show that there is a higher prevalence of depression among PLWHIV who are on ART in Africa. It is crucial to correctly recognise and provide proper care for depression to optimise HIV treatment and enhance treatment adherence in this population.

Effects of COVID-19, control measures, and program adaptation on prevention of mother-to-child HIV transmission service uptake in Central Region, Uganda

BACKGROUND

Coronavirus disease 2019 (COVID-19) control measures presented impediments for prevention of mother-to-child transmission of HIV (PMTCT) programming in Uganda. Nationwide control measures implemented April-June 2020 included a public transport ban and mandatory travel permits for pregnant women to access clinics. Program adaptations instituted for continuity of services included community drug delivery and home-based DNA-PCR testing for HIV-exposed infants (HEI). We examined the effect of COVID-19 control measures and program adaptations on PMTCT service uptake in central Uganda.

METHODS

We analysed data for pregnant women living with HIV (WLHIV) and HEI receiving PMTCT services in eight districts in central Uganda. We abstracted data from medical records at 96 public clinics for six months pre-lockdown (October 2019-March 2020), three months of lockdown (April-June 2020), and six months post-lockdown (July-December 2020). We measured monthly antiretroviral therapy (ART) refill attendance, health facility deliveries, and timely DNA-PCR testing of HEI for HIV (within two months of birth). We conducted segmented ordinary least squares regression of interrupted time series and adjusted for month-to-month changes using Cumby-Huizinga test. We reported results using coefficients and 95% confidence intervals (CIs).

RESULTS

At the start of pre-lockdown (October 2019), there were 448 deliveries, 2,676 ART refills and 556 timely HEI tests. The pre-lockdown trend for ART refills increased while deliveries and HEI tests declined. At the start of lockdown (April 2020), all indicators declined, although significantly for facility deliveries (-60; 95% CI: -102, -18). Lockdown monthly trends were positive with 68 more HEI tested per month (95% CI:42, 93) and 51 more deliveries (95% CI: 9, 94) but insignificantly negative for ART refills. At start of post-lockdown (July 2020), HEI testing declined (-28; 95%CI: -48, -8). Post-lockdown HEI testing trend was negative with 70 fewer HEI tested per month (95%CI: -79, -62) while no difference in trend for deliveries and ART refills.

CONCLUSION

COVID-19 control measures had a significant immediate negative impact on pregnancy deliveries at health facilities. During lockdown, all service rates rapidly recovered through program adaptations, significantly for HEI testing and deliveries. Maintaining these adaptations might help restore the positive trend in timely HIV testing for HEI.

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.

"It is because of the love for the job that we are still here": Mental health and psychosocial support among health care workers affected by attacks in the Northwest and Southwest regions of Cameroon

Attacks on health care have important consequences for the mental health (MH) and work availability of health care workers (HCW). In the conflict-affected Northwest and Southwest (NWSW) regions of Cameroon, health care attacks are common; however, little is known on the MH burden and/or (mental) health-seeking behavior among affected HCW. We therefore conducted a survey on mental conditions (relying on SRQ-20 and WASSS assessments) and access to MH services among 470 HCW from 12 districts in NWSW Cameroon in January-February 2022. In-depth interviews on personal experiences with attacks and on accessing MH services were conducted with a subset of 96 HCW. Among surveyed HCW, 153 (33%) had experienced an attack in the past 6 months, and a further 121 (26%) had experienced attacks more than 6 months ago. HCW facing attacks <6 months ago had significantly higher odds of exhibiting mental disorders (aOR 5.8, 95%CI 3.0-11.3, p<0.001) and of being unable to function (aOR 3.3, 95%CI 1.9-5.7, p<0.001). HCW who experienced an attack >6 months also had higher odds of being unable to function (aOR 2.9, 95%CI 1.7-5.2, p<0.001), and of missing time off work in the week preceding the survey (aOR 3.1, 95%CI 1.8-5.5, p<0.001). Previous access to MH services was also higher among HCW facing attacks. HCW showed a good understanding of the added values of accessing MH services, but faced multiple access barriers (including poor availability of services and their own prioritization of the care of others) and indicated a preference for self-care, peer-support and/or religious support. In conclusion, health care attacks in NWSW Cameroon contributed significantly to severe mental conditions and absenteeism rates among HCW. Strengthening access to MH support among attack-affected HCW is indicated; this should include strengthening of formal MH services and building the capacity of HCW and religious leaders to provide peer-support.

Factors associated with a measles outbreak in three health districts of Cameroon in 2019: a cross-sectional study

Introduction

measles is an infectious viral disease that affects susceptible individuals of all ages. It is a leading cause of death among young children globally due to suboptimal vaccination coverage. In 2019, measles outbreaks affected several parts of the world, including three health districts (HDs) of Cameroon's South West Region (SWR) experiencing armed conflict. Herein, we assessed the factors associated with the outbreak in the SWR.

Methods

we conducted a comparative study from March to August 2020. Data on study participants were compared between the three HDs that experienced a measles outbreak and three other HDs of the region that reported a case of measles but did not get into an outbreak. Records on vaccination between 2015 and 2019 were reviewed.

Results

information was obtained from 56 participants with known measles status, 32 from outbreak districts, and 24 from non-outbreak districts. The population in the outbreak group was more likely to have traveled from an area in a measles outbreak (OR 2, 95%CI 1.1-11.20). There was a suboptimal availability of measles vaccines in both categories of districts compared to the needs, and there was a downward trend in vaccination coverage in both groups. In addition, vaccines were more exposed to extreme temperatures in HDs with the outbreak (P<0.01) from 2015 to 2019. We found no statistically significant difference between both groups concerning the preexisting comorbidities of participants.

Conclusion

there is an urgent need to improve the cold chain and intensify vaccination activities in these districts.

Polio outbreaks in Cameroon following the COVID-19 pandemic

Polio is an infectious and disabling life-threatening disease caused by the poliovirus. This disease is prevented through vaccination. Though this viral infection has been eliminated in most parts of the world, a few countries are still endemic to wild poliovirus. In 2020, the World Health Organization (WHO) African Region, including Cameroon, was certified free of wild poliovirus. Some countries recurrently report circulating vaccine-derived poliovirus cases (cVDPV) despite recorded achievements. Also, the risk of importing poliovirus from endemic settings remains, particularly in the context of coronavirus disease (COVID-19). This study aimed to assess the state of polio in Cameroon and identify the situation during COVID-19. A data review was conducted from February to March 2023. Data on polio cases and vaccination coverage per region of Cameroon were reviewed from 2014 to 2022. Data were analyzed with Microsoft Excel, and the results were presented as proportions. The last wild poliovirus was reported in Cameroon in 2014, and the country benefitted from a response. No case of poliovirus was detected in the country from 2015 to 2018. After that, an increasing number of type two cVDPV were reported across 50% of the country's regions from 2019 to 2022. The outbreaks benefitted from responses with various oral polio vaccines, including the type two novel oral polio vaccine (nOPV-2). Though wild polioviruses have been eliminated in most countries, including Cameroon, cVDPV remains a significant problem. There is an urgent need to strengthen disease surveillance and vaccination to prevent cVDPV-2 in this country, particularly in the COVID-19 context.

Building on Capacity Established through US Centers for Disease Control and Prevention Global Health Programs to Respond to COVID-19, Cameroon

The COVID-19 pandemic has highlighted the need for resilient health systems with the capacity to effectively detect and respond to disease outbreaks and ensure continuity of health service delivery. The pandemic has disproportionately affected resource-limited settings with inadequate health capacity, resulting in disruptions in health service delivery and worsened outcomes for key health indicators. As part of the US government's goal of ensuring health security, the US Centers for Disease Control and Prevention has used its scientific and technical expertise to build health capacity and address health threats globally. We describe how capacity developed through global health programs of the US Centers for Disease Control and Prevention in Cameroon was leveraged to respond to coronavirus disease and maintain health service delivery. The health system strengthening efforts in Cameroon can be applied in similar settings to ensure preparedness for future global public health threats and improve health outcomes.

Conflict, healthcare and professional perseverance: A qualitative study in a remote hospital in an Anglophone Region of Cameroon

Armed conflicts are a major contributor to global disease burden owing to their deleterious effects on health and healthcare delivery. The Anglophone crisis in Cameroon is one of the ongoing conflicts in Sub-Saharan Africa and has led to massive displacement of healthcare workers (HCWs). However, some HCWs have stayed back and continued working. An understanding of their experiences, perspectives and professional perseverance is lacking. We designed a phenomenological study using Focused Group Discussions (FGDs) and in-depth interviews to: understand the experiences of 12 HCWs in a remote hospital in the North West region of Cameroon with armed groups; evaluate how it affects healthcare delivery from HCWs perspective and examine HCWs coping mechanisms during the conflict with a view of informing HCW protection policies in conflict zones. Results revealed that HCWs go through all forms of violence including threats, assaults and murders. Overall insecurity and shortage of health personnel were major barriers to healthcare delivery which contributed to underutilization of healthcare services. Participants observed an increase in complications due to malaria, malnutrition and a rise in maternal and infant mortality. The hospital management and Non-Governmental Organizations (NGOs) played an essential role in HCWs adaptation to the crisis. Nevertheless they unanimously advocated for a cease fire to end the conflict. In the meantime, passion for their job was the main motivating factor to stay at work.

Impact of periodic intensification of routine immunization within an armed conflict setting and COVID-19 outbreak in Cameroon in 2020

Introduction

Cameroon’s Southwest Region (SW) has been hit by an armed conflict for over half a decade now, negatively affecting the region’s routine immunization and disease surveillance activities. This negative effect was further acerbated by the COVID-19 pandemic, which alongside the conflict, caused thousands of children to miss out on life-saving vaccinations. Herein, we present the contribution of periodic intensification of routine immunization in improving immunization and surveillance activities amid crises.

Method

Periodic intensification of routine immunization (PIRI) and disease surveillance were carried out in three rounds per health district. Before the intervention, the security profile of each district involved was reviewed. Data for this study was extracted on vaccination and surveillance activities from the District Health Information Software and monthly regional reports for 2019 and 2020 from the SW delegation of health.

Results

54,242 persons were vaccinated in the SW following these interventions. An increase in performance was observed in all 18 health districts in 2020 compared to 2019. Both DPT-HebB-Heb-3 vaccine and OPV-3 coverage rose by 28% points. Similarly, the proportion of health districts that investigated at least a case of acute flaccid paralysis increased by 83%, rising from just three districts in 2019 to all 18 in 2020.

Conclusion

PIRI was a practical approach to improving vaccination coverage and surveillance indicators in this region amidst the ongoing armed conflict and COVID-19 pandemic.

Doctors’ experiences providing sexual and reproductive health care at Catholic Hospitals in the conflict-affected North-West region of Cameroon: a qualitative study

Background

Sexual and reproductive health (SRH) care services are essential to improving the lives of women and achieving the Sustainable Development Goals. In Cameroon, the Catholic Church is one the largest non-governmental suppliers of health care, but its role in providing SRH care is restricted by religious norms.

Methods

This study explored doctors’ experiences and perceptions of providing SRH care at Catholic hospitals in a conflict-affected area in Cameroon by using 10 in-depth interviews with doctors from three Catholic hospitals in the North-West region. Qualitative coding was done with NVivo, and data were analysed using thematic analysis.

Results

Three themes and seven categories were identified. The respondents described strict rules and a broad range of challenges to providing comprehensive sexual and reproductive health care services. Nonetheless, there is evidence of doctors overcoming obstacles to providing SRH care despite the religious and political climate. However, whilst attempting to overcome challenges, participants described numerous examples of poor SRH care and health outcomes.

Conclusion

The study highlights the importance of understanding the intersect between religion and women’s health, particularly in improving access to SRH for vulnerable populations in conflict-affected areas. It further provides insight into doctors’ motivations in practicing medicine and how doctors cope and make efforts to provide care and minimize harm.

The main aim of this study was to explore doctors’ experiences and perceptions of providing sexual and reproductive health care services at Catholic hospitals in a conflict affected area in Cameroon. In Cameroon, sexual, and reproductive health services are lacking, thereby contributing to a very high maternal mortality rate of about 456/100000 live births, far from the Sustainable Development Goal Agenda 2030. The Catholic Church remains one of the largest suppliers of health care services in Cameroon and receives huge funding from donors, but their role in providing sexual and reproductive health care is restricted by religious norms. This study therefore uses in-depth interviews with doctors from Catholic hospitals in the North-West region to explore their experiences in providing sexual and reproductive health services in a conflict region. Qualitative coding was done with NVivo, and data analysed using thematic analysis. The respondents described strict rules and a broad range of challenges to providing comprehensive sexual and reproductive health care services. Nonetheless, there is evidence of doctors overcoming obstacles to providing sexual and reproductive health (SRH) care despite the religious and political climate. However, while attempting to overcome challenges, participants describe numerous examples of poor SRH care and poor health outcomes. The study highlights the importance of understanding the intersect between religion and women’s health, particularly in improving access to SRH for vulnerable populations in conflict affected areas. It further provides insight into doctors’ motivations for practicing medicine, and how doctors cope and make efforts to provide care and minimize harm.

COVID-19 in a region of Cameroon hit by armed conflict

INTRODUCTION

the emergence of more transmissible SARS-CoV-2 variants like Delta and Omicron have triggered the next wave of COVID-19 in many parts of the world. Here we report a surge in COVID-19 cases and deaths in the Northwest (NW) Region of Cameroon, which is plagued with low immunization coverage and armed conflict.

METHODS

a cross-sectional study was conducted in September 2021 and data on COVID-19 cases and vaccination were reviewed from the Ministry of Health database from January 1st, 2020 to September 4th, 2021. The security situation of the region was obtained from the districts and regional health managers. Data were analyzed with MS Excel and results presented as trends and proportions.

RESULTS

since the onset of COVID-19 pandemic, there is an increasing prevalence in cases in the NW. Between epidemiological week 34-35 of 2021, there was a surge in COVID-19 cases in the NW. More than 70% of all COVID-19 related deaths reported in the country during epidemiological week-35 were recorded in this region. Despite this high mortality, COVID-19 vaccine uptake remains very low in the region. Indeed, just 0.6% of the 962,036-target population 18-years and above are fully immunized after 6-months of vaccination.

CONCLUSION

though the country´s epi-curve does not suggest a third wave currently, the NW is experiencing a steady COVID-19 case surge amid insecurity and the circulation of the Delta variant. There is therefore a need to adopt innovative strategies to improve immunization and strengthen other SARS-CoV-2 preventive measures in this region.

Urogenital schistosomiasis burden in school-aged children in Tiko, Cameroon: a cross-sectional study on prevalence, intensity, knowledge and risk factors

Background

This study aimed at determining urogenital schistosomiasis (UGS) prevalence, intensity, knowledge and risk factors in school-aged children (SAC) in the new endemic focus of Tiko, Cameroon.

Methods

A cross-sectional study including 389 SAC of both sexes aged 5–15 years was carried out between April and June 2018. A structured questionnaire was used to collect demographic data, clinical and predisposing factors. Urine sample collected was used to detect Schistosoma haematobium eggs by filtration technique and microhaematuria by Heme dipstick COMBI 11. Logistic regression model was used to determine risk factors of UGS.

Results

The overall prevalence of UGS was 37.0% (CI 32.4–41.9) and 32.6% (CI 28.2–37.5) were positive by egg excretion while 24.4% (CI 20.4–28.9) by haematuria. S. haematobium egg excretion and haematuria were significantly higher in males (P = 0.016; P = 0.049) and children 12–15 years old (P = 0.009; P = 0.002), respectively. The mean number of eggs per 10 mL of urine was 77.6 (10.2) and ranged from 2 to 400. The proportion of light intensity of infection was higher (67.7%, CI 59.2–75.2) with no significant differences by sex, age and residence. However, the older children were more heavily infected when compared to the younger children, who had more of light infection. Overall, the mean knowledge score 1.42 (CI 1.32–1.51) on a scale of 6, was poor and the proportion of good knowledge of the disease (23.14%, CI 19.2–27.6) was low. Stream water contact (AOR = 4.94; P = 0.001) was the only significant risk factor identified.

Conclusion

Urogenital schistosomiasis is of public health concern among SAC in Tiko, Cameroon. Most participants have poor knowledge about the disease, hence education on vector-borne diseases and the avoidance of stream water contact should be implemented.
