RESUMO

OBJECTIVES: To determine the prevalence, case-fatality rate, and associated risk-factors of Noma in children in Nigeria. METHODS: Search was conducted in PubMed, Google Scholar, and Cochrane Library databases. Data were extraction using a double-blind approach. Discrepancies were resolved by a third reviewer. Heterogeneity was evaluated using I2 statistics. Random-effects model was used for the meta-analysis and subgroup analysis was conducted. The study quality was evaluated using standard Critical-Appraisal-Checklist. RESULTS: Of the 1652 articles identified, 12 studies that met the inclusion criteria included 871 cases of Noma. Two studies had high-risk of bias and were excluded in the meta-analysis. Pooled prevalence of Noma was 2.95% (95%CI:2.19-3.71; Z = 7.60; p < 0.00001, I2:100.0). Case fatality was reported in one study. Sex-distribution had a male-to-female ratio of 1.1:1. Malnutrition (88.42%, 95%CI:52.84-124.00; I2:100.0), measles (40.60%; 95% CI:31.56-49.65; I2:100.0) and malaria (30.75%; 95% CI:30.06-31.45; I2:100.0) were the most notable associated risk-factors. Prevalence of Noma was non-significantly lower in southern (1.96%,95%CI:1.49-2.44;6 studies) than in northern (4.43%; 95%CI:-0.98-9.83; 4 studies) Nigeria. One study reported the prevalence of Noma in children younger than 5 years. CONCLUSIONS: About every 3 in 100 children in Nigeria had Noma and the prevalence was non-significantly higher in northern than southern Nigeria. Malnutrition, measles, and malaria were major associated risk-factors. Case-fatality rate and prevalence based on different age-groups were inconclusive.

RESUMO

Population-based study is known to be a very essential type of study during and after a pandemic or epidemic, as it provides crucial information on the incidence, prevalence, and risk factors of the disease in question. There has been limited information about the challenges faced in conducting such surveys in Nigeria. In this paper, we will share our experience, and describe the challenges faced in conducting a population-based seroepidemiological study of COVID-19 in Lagos, Nigeria. Some challenges were peculiar to specific Local Government Areas (LGAs) while others were general. The challenges include general misconceptions of community members about health research, difficulties in mapping houses, planning for data collection, standardizing data collection, working in hard-to-reach communities when resources were limited as well as difficulty in collection of blood and naso-oropharyngeal swabs. Ways of overcoming these problems, lessons learnt, and recommendations are hereby discussed.

RESUMO

BACKGROUND: Soil-transmitted helminthiasis (STH) and schistosomiasis (SCH) are among the most prevalent neglected tropical diseases (NTDs), affecting 1.5 billion globally, with a significant burden in sub-Saharan Africa, particularly Nigeria. These diseases impair health and contribute to socio-economic challenges, especially in children, undermining educational and future economic prospects. The 2030 NTD Roadmap highlights Mass Drug Administration (MDA) as a critical strategy for controlling these NTDs, targeting vulnerable populations like school-age children. Despite some successes, challenges persist, indicating the need for deeper insights into program implementation. This study focuses on the perspectives of health workers implementing MDA in selected local government areas (LGAs) of Ogun State, Nigeria, aiming to identify challenges and enablers that align with the broader NTD 2030 goals. METHODOLOGY/PRINCIPAL FINDINGS: The study used a qualitative research approach involving focus group discussions and in-depth interviews with health workers engaged in neglected tropical disease control programs in Ogun State, Nigeria, between July and September 2022. A semi-structured questionnaire guided the exploration of ideas, and the data were analyzed using the QRS Nvivo 12 software package. The study found that the school-based MDA control program's efficacy largely relies on strong collaborations and partnerships, particularly with educators, community heads, and other stakeholders. These alliances and strategic communication methods, like town announcements and media campaigns, have been pivotal in reaching communities. However, the program does grapple with hurdles such as parental misconceptions, limited funds, insufficient staffing, and misalignment with the Ministry of Education. It is recommended to boost funding, foster early stakeholder involvement, enhance mobilization techniques, and consider introducing a monitoring card system similar to immunization. CONCLUSIONS/SIGNIFICANCE: The MDA Integrated Control Programs for STH and SCH in Ogun State schools demonstrate a holistic approach, integrating knowledge, collaboration, communication, and feedback. Health workers have shown commitment and adeptness in their roles. However, achieving maximum efficacy requires addressing critical barriers, such as parental misconceptions and funding challenges. Adopting the recommended strategies, including proactive communication, increased remuneration, and introducing a tracking system, can significantly enhance the program's reach and impact. The involvement of all stakeholders, from health workers to community leaders and parents, is essential for the program's sustainability and success.

RESUMO

The awareness of the health implication of Covid-19 pandemic marked an increase consumption of various dietary and herbal supplements (DHS) for the deterrence and/or prophylaxis against the novel emerging and infectious disease. However, there is little indication of the usefulness or otherwise of their use in alleviating symptoms of COVID-19. Objectives: To investigate the pattern and determinants of DHS use among the Nigerian population for the prevention and treatment of COVID-19. Design: Cross-sectional questionnaire survey. Setting: Older adolescents and adults residing in Nigeria. Participants: Participants (n = 645) residing in the Nigeria were recruited from different geo-political zones and various ethnic groups. Primary and secondary outcomes: Prevalence and determinants for the use of different DHS for the prevention and treatment of COVID-19 in Nigeria, and sources of information for DHS use. Results: Most participants (425, 65.9%) believed that dietary supplements are necessary during infectious disease outbreak, but a fewer proportion believed that supplements can be used in conjunction with other drugs to treat Covid-19. Vitamin C was the most known (70.0%) and Vitamin A. The least known (0.3%) dietary supplement Approximately half (50.2%) of the study subjects, more than a third (37.8%) and less than a quarter (22.7%) were aware that Folic acid, vitamin D and vitamin E are DS. Herbal dietary supplements mentioned as known by the study participants included Garlic (46.5%), Ginger (44.7%), Tumeric (36.3%), Moringa (40.0%) and Ginseng (26.3%). Citrus fruit as a DS was recognized by fewer (6.5%) study participants and only 1.6% referred to herbal tea as DHS. In all, 571 (88.5%) of the study participants took DHS during the Covid-19 pandemic with males 1.5 times more likely to take DHS than females (χ2 = 3.09, P-value = 0.08, OR = 1.54, 95% CI = 0.95, 2.47) during the pandemic. Participants reported lesser consumption of Selenium (27, 4.2%), Iron (20,3.1%), Zinc (61, 9.5%) and calcium (101, 15.7%) to prevent/treat Covid-19. Majority (271, 42.0%) of the study participants mentioned "health worker" as source of information on DHS while 13% mentioned "Social media". The sociodemographic determinants of DHS practices used to prevent/treat COVID-19 during the pandemic included older age group of 61-70 years, widows, secondary level of education and not employed. Conclusions: The findings showed widespread use of DHS for the prevention and treatment of COVID-19. The use of DHS in this study was mainly guided by health workers with a marginal role of social media and Mass media. These findings call for a more robust consolidative tactic towards DHS to ensure its proper and safe use.

RESUMO

OBJECTIVE: We conducted a systematic review and meta-analysis to determine the prevalence of high-risk human papillomavirus (hrHPV) infection and its associated risk factors among Nigerian women. METHODS: Databases including PubMed, Web of Science, Scopus, and CINAHL were searched for studies published between 01 January 2001 and 31 December 2022, that had reported hrHPV infection and associated risk factors among women in Nigeria from ages of 25 to 65 years. RESULTS: Of the 136 records initially retrieved, 18 were eligible for analysis. The prevalence of hrHPV genotypes was 25%, and for hrHPV 16 and 18, were 9% and 10%, respectively. The prevalence of hrHPV among HIV+ve women was 71%. The most common risk factors for hrHPV were age at coitarche and multiple sex partners. CONCLUSION: hrHPV prevalence is high in women in Nigeria and common among those HIV+ve. Rapid screening for hrHPV genotypes is recommended, and multivalent HPV vaccines should be considered for women.

RESUMO

Introduction: Pregnancy often intensifies psychological vulnerabilities in women living with HIV (WLHIV) due to increased stressors such as health concerns, infant infection risks, and the management of special neonatal needs like prophylactic antiretroviral care. Methodology: The study was conducted in four HIV treatment centres with participant selection based on the following criteria: an Edinburgh Postnatal Depression Scale (EPDS) score of 13 or above, gestational age between 14 to 40 weeks, less than five years of antiretroviral therapy (ART) usage, and history of partner conflict. This research forms a more extensive study of stress and depression amongst pregnant and postpartum WLWH. In-depth interviews, ranging from 20 to 40 minutes, were conducted with 26 HIV-positive pregnant women in private rooms within selected antiretroviral clinics from October and December 2022. Results and Discussion: The study discovered that the support received from healthcare providers concerning ART and Prevention of Mother-To-Child Transmission (PMTCT) practices alleviated women's fear of death and perinatal transmission which bolstered their involvement in HIV care and fostered the birth of children not infected with HIV. Women perceived monogamy as a protective measure against HIV contraction. Participants who reported having partners engaging in unsafe sexual practices expressed anger and blame. The observation of other women with similar experiences aided in coping mechanisms, reaffirming previous findings that knowing someone living with HIV helps to accept their status due to the comfort derived from shared experiences. Conclusion: Healthcare providers attending to pregnant WLWH can alleviate psychological distress by reinforcing positive coping strategies. These include consistent psychological distress screenings in HIV clinics and relevant mental health evaluations with appropriate care referrals.

RESUMO

BACKGROUND: Machine learning (ML) prediction models to support clinical management of blood-borne viral infections are becoming increasingly abundant in medical literature, with a number of competing models being developed for the same outcome or target population. However, evidence on the quality of these ML prediction models are limited. OBJECTIVE: This study aimed to evaluate the development and quality of reporting of ML prediction models that could facilitate timely clinical management of blood-borne viral infections. METHODS: We conducted narrative evidence synthesis following the synthesis without meta-analysis guidelines. We searched PubMed and Cochrane Central Register of Controlled Trials for all studies applying ML models for predicting clinical outcomes associated with hepatitis B virus (HBV), human immunodeficiency virus (HIV), or hepatitis C virus (HCV). RESULTS: We found 33 unique ML prediction models aiming to support clinical decision making. Overall, 12 (36.4%) focused on HBV, 10 (30.3%) on HCV, 10 on HIV (30.3%) and two (6.1%) on co-infection. Among these, six (18.2%) addressed the diagnosis of infection, 16 (48.5%) the prognosis of infection, eight (24.2%) the prediction of treatment response, two (6.1%) progression through a cascade of care, and one (3.03%) focused on the choice of antiretroviral therapy (ART). Nineteen prediction models (57.6%) were developed using data from high-income countries. Evaluation of prediction models was limited to measures of performance. Detailed information on software code accessibility was often missing. Independent validation on new datasets and/or in other institutions was rarely done. CONCLUSION: Promising approaches for ML prediction models in blood-borne viral infections were identified, but the lack of robust validation, interpretability/explainability, and poor quality of reporting hampered their clinical relevance. Our findings highlight important considerations that can inform standard reporting guidelines for ML prediction models in the future (e.g., TRIPOD-AI), and provides critical data to inform robust evaluation of the models.

RESUMO

Health-Related Quality of Life (HRQL) is commonly used to assess the impact of health status on quality of life. The HRQL data obtained does not follow the assumption of normality and a non-parametric test was used to make inference in this study. This study compares the characteristics of children with HRQL classified as good, intermediate, and poor quality of life. The children and adolescents that have a good health-related quality of life had a mean rank of 75.5, intermediate, 27.0 while children and adolescents with poor HRQL had a mean rank of 8.5. The health -related quality of life differs significantly across the demographic characteristics. However, tertiary education does not differ significantly on HRQL. The Kruskal-Wallis's chi-squared was 76.95 with two degrees of freedom and p-value < 2.2e-16. The p-value < 0.05 indicates sufficient evidence that HRQL of children and adolescents differs significantly across the three categories. Conclusively, children and adolescents in the three categories have different quality of life. It is clear that most of the children and adolescents had a good health-related quality of life once they have been taking their drugs regularly as prescribed by the physician.

RESUMO

BACKGROUND: Neglected tropical diseases, such as soil-transmitted helminths and Schistosomiasis, are prevalent in sub-Saharan Africa, particularly Ogun State, Nigeria. School-based mass drug administration program is the primary control intervention, but the coverage and uptake of this intervention have been inadequate. This study aimed to investigate community perceptions of school-based mass drug administration programs for these infections in Ogun State, Nigeria, and identify the barriers to their uptake and coverage. METHODOLOGY/PRINCIPAL FINDINGS: The study used a qualitative research approach involving focus group discussions and in-depth interviews with community members and stakeholders engaged in neglected tropical disease control programs in Ogun State, Nigeria. A semi-structured questionnaire guided the exploration of ideas, and the data were analyzed using the QRS Nvivo 12 software package. The study found several barriers, such as the influence of parents, lack of sufficient knowledge, and side effects. The study recommended strategies such as improving community sensitization and engagement, drug distribution and performance, and enhancing partner collaboration and coordination to improve the school-based mass drug administration programs. CONCLUSIONS/SIGNIFICANCE: The study revealed correct perceptions of transmission but some misconceptions about disease causation, transmission, and drug safety. Participants expressed a desire for better sensitization campaigns and more assurances of their safety. The study recommends strengthening health education messages and increasing the visibility of on-site medical personnel. The findings have implications for improving the performance of these programs and reducing the burden of intestinal parasitic infections in the community. The study highlights the need for community engagement and education, health system support, and partner collaboration to successfully implement mass drug administration programs.

RESUMO

BACKGROUND: Human papillomavirus (HPV) is responsible for most cervical cancer cases globally, with women living with HIV having a higher risk of persistent HPV infection and HPV-associated disease. The HPV vaccine is a promising tool to reduce cervical cancer rates, but its uptake among women living with HIV in Nigeria is unknown. METHODS: A facility-based, cross-sectional survey was conducted with 1371 women living with HIV to assess their knowledge of HPV, cervical cancer, and the HPV vaccine as well as their willingness to pay for the vaccine at the HIV treatment clinic at the Nigerian Institute of Medical Research, Lagos. To identify factors associated with the willingness to pay for the HPV vaccine, multivariable logistic regression models were developed. RESULTS: This study found that 79.1% of participants had not heard of the vaccine, and only 29.0% knew its efficacy in preventing cervical cancer. In addition, 68.3% of participants were unwilling to pay for the vaccine, and the average amount they were willing to pay was low. Knowledge of HPV, the HPV vaccine, and cervical cancer and income were factors associated with the willingness to pay for the vaccine. Health workers were the primary source of information. CONCLUSIONS: This study highlights the lack of knowledge and low willingness to pay for the HPV vaccine among women living with HIV in Nigeria and emphasizes the importance of improving education and awareness. Factors associated with the willingness to pay, such as income and knowledge, were identified. Practical strategies, such as community outreach and school-based education programs, could be developed to increase vaccine uptake. Further research is needed to explore additional factors influencing the willingness to pay.

RESUMO

Background: Pregnancy and postpartum periods are crucial stages for women's mental health, and women living with HIV are particularly susceptible to depression and psychological stress due to various factors. This study investigated the prevalence and associated factors of depression and perceived stress among women living with HIV during their perinatal period in Ibadan, Nigeria. Methods: A cross-sectional survey was conducted in three HIV treatment centers in Ibadan, Nigeria, among women living with HIV between the ages of 19 and 49 who were either pregnant or had given birth within the last 2 years. The study was conducted from September 2022 to December 2022. An interviewer-administered questionnaire was used to collect the data from the participants. Ethical approval and informed consent were obtained, and data were analyzed using the Statistical Package for Social Science version 26. Results: The study included 402 participants, of whom 69.0 and 78.0% reported symptoms of depression and perceived stress, respectively. However, 15.2% of the participants have comorbid depression and stress. Positive partner status was significantly associated with lower perceived depression, while gestational age between 29 and 40 weeks was significantly associated with lower perceived stress. The co-occurrence of depression and perceived stress was associated with partner status, income level, family support, gestational age, and years on antiretroviral therapy. Conclusion: The high prevalence of depression, perceived stress, and their co-occurrence among women living with HIV during the perinatal period call for incorporating mental health care into routine maternal healthcare for all women, particularly those living with HIV. This finding emphasizes the need for public health efforts to prioritize perinatal mental health and improve access to care and support for women and their partners.

RESUMO

BACKGROUND: Coagulation abnormality is a significant complication and cause of mortality in children with uncorrected congenital heart defects (CHD). The aim of this study was to determine the prevalence of coagulation abnormalities and the associated factors in children with uncorrected CHD. METHOD: A cross sectional study conducted to determine the prevalence of coagulation abnormalities among 70 children with uncorrected CHD aged six months to 17 years and 70 age and sex matched apparently healthy controls. Coagulation abnormalities was determined using complete blood count, prothrombin time, activated partial thromboplastin time and D-dimer assay. RESULTS: The prevalence of coagulation abnormalities among children with CHD and controls was 37.1% and 7.1% respectively. Children with Cyanotic CHD had a significantly higher prevalence of coagulation abnormalities compared to children with Acyanotic CHD (57.1% versus 17.1%). Haematocrit and oxygen saturation levels were significantly associated with coagulation abnormalities. CONCLUSION: This study affirms that coagulation abnormalities are frequent in children with uncorrected CHD. Oxygen saturation and haematocrit are risk factors of coagulation abnormalities. Routine coagulation screen is recommended especially in children with cyanotic congenital heart defects to improve their quality of life and reduce morbidity and mortality while awaiting definitive surgeries.

RESUMO

Introduction: adolescents living with HIV [ALHIV] face the dual challenges of adolescence and coping with HIV infection. This study aims to evaluate health-related quality of life [HRQoL] of children and adolescents aged 8 - 18 years living with HIV in an HIV treatment centre in Lagos, Nigeria. Methods: we conducted a cross-sectional study among children and adolescents living with HIV and receiving antiretroviral therapy. HRQoL was assessed using the Paediatric Quality of Life Inventory [PedQoL™]. Socio-demographic data and HIV related clinical and laboratory characteristics were also obtained and tested based on HRQoL scores in order to determine if there were possible associations. Results: the study included 113 participants with a mean age of 14 (± 2.9) years. There was male predominance, with a male: female sex ratio of 1.1: 1. The mean duration of ART was 102.9 (±36.9) months and CD4 lymphocyte count was and 741.2 (±335.7) cell/mm3. The majority of participants (62%) were also virally suppressed. Based on self-reported data, the mean physical, psychosocial and total HRQoL scores were 85.0 [± 22.4], 78.5 [±17.5] and 81.6 [±18.4] respectively. Adolescents aged 13-18 years had significantly higher scores than children aged 8-12 years. Male patients who had been on ART for ≥60 months were also significantly associated with higher HRQoL scores (OR=5.46 [CI= 2.24-13.29], p = 0.0009) and OR= 4.80, [CI= 1.58 - 14.56] p = 0.0032). Conclusion: the majority of participants in the study had good HRQoL scores, attesting to the success of highly active antiretroviral therapy for HIV infection and the ease of access and availability to a comprehensive care.

RESUMO

Real-world data on vaccine-elicited neutralising antibody responses for two-dose AZD1222 in African populations are limited. We assessed baseline SARS-CoV-2 seroprevalence and levels of protective neutralizing antibodies prior to vaccination rollout using binding antibodies analysis coupled with pseudotyped virus neutralisation assays in two cohorts from West Africa: Nigerian healthcare workers (n = 140) and a Ghanaian community cohort (n = 527) pre and post vaccination. We found 44 and 28% of pre-vaccination participants showed IgG anti-N positivity, increasing to 59 and 39% respectively with anti-receptor binding domain (RBD) IgG-specific antibodies. Previous IgG anti-N positivity significantly increased post two-dose neutralizing antibody titres in both populations. Serological evidence of breakthrough infection was observed in 8/49 (16%). Neutralising antibodies were observed to wane in both populations, especially in anti-N negative participants with an observed waning rate of 20% highlighting the need for a combination of additional markers to characterise previous infection. We conclude that AZD1222 is immunogenic in two independent West African cohorts with high background seroprevalence and incidence of breakthrough infection in 2021. Waning titres post second dose indicates the need for booster dosing after AZD1222 in the African setting despite hybrid immunity from previous infection.

RESUMO

The SARS-CoV-2 virus is highly infectious resulting in increased infection and death among the front-line Healthcare Workers (HCW) because of limited access to personal protective equipment (PPE). This study assesses the availability and self-reported use of PPE amongst HCW during the COVID-19 pandemic in Nigeria. A mixed-method study was conducted through a cross-sectional survey and in-depth interviews amongst HCW. Quantitative data analysis was done using SPSS version 26 and thematic analysis was done for the in-depth interview. A total of 258 HCW completed the survey while 15 HCW took part in the in-depth interview. The mean age was 40 (±8.6) years, 67.4% were female and 83.3% were married. 49% were Doctors, 21.1% were Nurses, 28.7% were other allied HCW and 62.2% had at least 10 years of practice experience. Only 22.1% of HCWs had regular access to PPE and only 20.6% had access to N-95 facemask compare to other PPEs. Male HCWs and those working at secondary or tertiary facilities had access to N-95 facemask (p-value 0.025 and 0.010 respectively). The facilitator of PPE use is leadership quality of hospital head and donation of PPE to the facilities while the barriers to PPE use include a limited supply of PPE, as well as facility's infrastructural and operational challenges. The study reported limited access to essential PPE with varying perspectives on its use. Therefore, access, knowledge, and appropriate use of PPE need urgent attention with improved implementation of infection control policy at the facility level.

RESUMO

BACKGROUND: The objective of this study was to describe the prevalence and clinical features of coronavirus disease 2019 (COVID-19) among children (≤18 years) evaluated for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection at a testing centre in Lagos, Nigeria. Methodology. This was a retrospective study. Data on the sociodemographic, clinical characteristics and SARS-CoV-2 results of participants at a modified drive-through centre for COVID-19 test sample collection over four months were retrieved from the electronic medical records (EMR). Data obtained were analyzed using SPSS version 22.0. RESULTS: A total of 307 children (≤18 years) were evaluated in this review. The prevalence of SARS-CoV-2 infection among the paediatric population was 16.3%. The median age (interquartile range (IQR)) was 9 (4-14) years. Common symptoms reported by the positive cases were fever (40.0%), cough (32.9%), sore throat (17.1%), and runny nose (15.7%). The majority of the positive cases had mild symptoms. Fever and sore throat were associated with the positive cases. CONCLUSION: Fever and sore throat were associated with SARS-CoV-2 infection among our cohort which buttresses the need for a high level of suspicion and clinical acumen in the management of common febrile diseases in paediatric settings.

RESUMO

OBJECTIVES: Optimising antibiotic use in healthcare settings through antimicrobial stewardship programmes (ASPs) is critical to effectively treat infections, protect patients from harms caused by unnecessary antibiotic use, and combat antimicrobial resistance. This needs assessment was designed to provide the current status of ASPs in healthcare facilities in Lagos State and identify gaps for future interventions. METHODS: A descriptive cross-sectional survey was conducted using a self-administered questionnaire to ascertain the extent and nature of ongoing ASPs among selected healthcare facilities and identify gaps for future interventional studies. RESULTS: Of 32 questionnaires distributed, 25 (78%) were completed and returned from three tertiary, six secondary, eleven primary and five private healthcare facilities. The mean years of practice of respondents was 13.96 ± 7.8 years (2-31 years). Six facilities (24%) had a team responsible for ASP operating at varying degrees of capacity, while five (20%) had a formal ASP. All six facilities with an antimicrobial stewardship (AMS) team had a medical doctor as the team lead, and 5 (20%) also had a pharmacist involved in implementation efforts. Routine pre-authorisation for specific antibiotic was performed in six facilities (24%), four of which monitor pre-authorisation interventions. Only two facilities (8%) performed prospective audit and feedback for specific antibiotic agents. Private healthcare facilities were more likely to have information technology (IT) capability to support the needs of AMS activities. CONCLUSION: This study revealed minimal ASP activities in healthcare facilities in Lagos State and highlighted possibilities of leveraging on available IT resources for a co-ordinated AMS strategy.

RESUMO

INTRODUCTION: The study was carried out to determine the prevalence of and risk factors for hepatitis B and C viral co-infections in HIV infected children in Lagos. METHOD: A cross-sectional study conducted to determine the prevalence and risk factors for hepatitis B and C viral co-infection in children aged 2 months to 13 years. There were 187 HIV infected and 187 HIV naïve age, sex-matched controls. Blood samples of participants were assayed for the serologic markers [HBsAg, anti-HBc, and anti-HCV)] of HBV and HCV viral infections using the Enzyme-Linked Immunosorbent assay (ELISA) method. RESULT: The prevalence of HBV infection using HBsAg was 5.3% and 4.8% (p = 0.814), among HIV-infected and HIV naïve children respectively, while using anti-HBc the prevalence was 7.0% and 7.5% (p = 0.842) among HIV- infected and HIV naïve children respectively. The prevalence of HCV infection among HIV- infected and HIV naive children were equal to 0.5% (p = 1.000). There was also no significant association with the identifiable risk factors (sharing of a toothbrush, sharing of needles, incision marks/tattoo, hepatitis B immunization status, history of blood transfusion, previous surgical operation, sexual exposure/abuse, history of jaundice, and genital circumcision) and the HBV and or HCV status among both groups of children. History of sexual exposure/abuse and history of jaundice were however found to be predictors of the presence of HBsAg among HIV infected children only, using a binary logistic regression model. CONCLUSION: The prevalence of HBV and or HCV infection among HIV-infected children is similar to the prevalence among HIV naïve children, suggesting that HIV-infected children are not more predisposed to viral hepatitis than healthy children. Also, there was no significant difference in the prevalence of HBV infection irrespective of the use of HBsAg or anti-HBc.

RESUMO

INTRODUCTION: effective and safe means of sample collection is a crucial component of testing for Covid-19. Uptake of testing is key to containing and controlling the spread of the virus. Scientists have been working on various strategies that will increase the uptake of testing for COVID-19. One such method involves the use of the drive-through sampling strategy. METHODS: data was collected by both qualitative and quantitative methods. An eligibility form was filled online. While in-depth interviews were conducted for the qualitative aspect of the study. RESULTS: 2,600 visits were recorded at the website, 2300 (88.46%) participants successfully registered for the test. 57.4% were found eligible of which 78.0% presented for the test. This Consisted of 78.0% drive-through and 22.0% walk-in. The average time for transiting through the drive-through site was 19.2 ± 4.6minutes while that of the walk-in was 28 ± 9.2min. This difference was statistically significant (p<0.001). In the qualitative component, respondents opined that maximum safety measures were deployed to protect both participants and health workers. Most said that the turnaround time for the sampling process was short. CONCLUSION: the sampling strategy although largely successful, is largely dependent on Internet penetrability, thus this sampling modality will be best utilized as an adjunct to established models of sample collection.
