RESUMO
BACKGROUND: Owing to crowded and unsanitary conditions, internally displaced persons (IDPs) have an increased risk of COVID-19 infection. Adoption of COVID-19 preventive measures among this population is premised on accurate information, adequate knowledge, and risk perception. We assessed COVID-19 knowledge and risk perception and investigated the association between risk perception and COVID-19 preventive measures, including vaccination among IDPs in Northeast Nigeria. METHODS: We conducted a cross-sectional study during July-December 2022 and sampled 2,175 IDPs using stratified sampling. We utilized a 12-point assessment tool to evaluate COVID-19 knowledge. Participants who scored ≥ 6 points were considered to have adequate knowledge. We used a 30-item Risk Behavior Diagnosis Scale to assess COVID-19 risk perception and evaluated each item on a 5-point Likert scale. Participants were divided into risk perception categories by the median of Likert scale scores. We performed weighted logistic regression analysis to identify factors associated with risk perception. Pearson's chi-squared with Rao-Scott adjustment was used to determine the relationship between risk perception and COVID-19 preventive measures. RESULTS: Of 2,175 participants, 55.7% were 18-39 years old, 70.9% were females, and 81.7% had no formal education. Among the IDPs, 32.0% (95% CI: 28.8 - 35.0) were considered to have adequate COVID-19 knowledge, and 51.3% (95% CI: 47.8 - 54.8) perceived COVID-19 risk as high. Moreover, 46.3% (95% CI: 42.8 - 50.0) had received one dose of COVID-19 vaccine, and 33.1% (95% CI: 29.8 - 36.0) received two doses. Adequate knowledge (Adjusted Odds Ratio (AOR) = 2.10, [95% CI: 1.46 - 3.03]) and post-primary education (AOR = 3.20, [95% CI: 1.59 - 6.46]) were associated with risk perception. Furthermore, high risk perception was significantly associated with wearing face masks (χ2 = 106.32, p-value < .001), practicing hand hygiene (χ2 = 162.24, p-value < .001), physical distancing (χ2 = 60.84, p-value < .001) and vaccination uptake (χ2 = 46.85, p-value < .001). CONCLUSIONS: This study revealed gaps in COVID-19 knowledge, risk perception, and vaccination uptake but demonstrated a significant relationship between risk perception and COVID-19 preventive practices. Health education and risk communication should be intensified to improve knowledge, elicit stronger risk perception, and enhance COVID-19 preventive practices.

Zero-dose (ZD) children is a critical objective in global health, and it is at the heart of the Immunization Agenda 2030 (IA2030) strategy. Coverage for the first dose of diphtheria-tetanus-pertussis (DTP1)-containing vaccine is the global operational indicator used to estimate ZD children. When surveys are used, DTP1 coverage estimates usually rely on information reported from caregivers of children aged 12-23 months. It is important to have a global definition of ZD children, but learning and operational needs at a country level may require different ZD measurement approaches. This article summarizes a recent workshop discussion on ZD measurement for targeted surveys at local levels related to flexibilities in age cohorts of inclusion from the ZD learning Hub (ZDLH) initiative-a learning initiative involving 5 consortia of 14 different organizations across 4 countries-Bangladesh, Mali, Nigeria, and Uganda-and a global learning partner. Those considerations may include the need to generate insights on immunization timeliness and on catch-up activities, made particularly relevant in the post-pandemic context; the need to compare results across different age cohort years to better identify systematically missed communities and validate programmatic priorities, and also generate insights on changes under dynamic contexts such as the introduction of a new ZD intervention or for recovering from the impact of health system shocks. Some practical considerations such as the potential need for a larger sample size when including comparisons across multiple cohort years but a potential reduction in the need for household visits to find eligible children, an increase in recall bias when older age groups are included and a reduction in recall bias for the first year of life, and a potential reduction in sample size needs and time needed to detect impact when the first year of life is included. Finally, the inclusion of the first year of life cohort in the survey may be particularly relevant and improve the utility of evidence for decision-making and enable its use in rapid learning cycles, as insights will be generated for the population being currently targeted by the program. For some of those reasons, the ZDLH initiative decided to align on a recommendation to include the age cohort from 18 weeks to 23 months, with enough power to enable disaggregation of key results across the two different cohort years. We argue that flexibilities with the age cohort for inclusion in targeted surveys at the local level may be an important principle to be considered. More research is needed to better understand in which contexts improvements in timeliness of DTP1 in the first year of life will translate to improvements in ZD results in the age cohort of 12-23 months as defined by the global DTP1 indicator.
RESUMO
The attainment of the global target of zero dog-mediated human rabies by 2030 depends on functional rabies programmes. Nigeria, a rabies-endemic country, and the most populous country in Africa has a very poor rabies control strategy with a score of 1.5 out of 5 based on the Stepwise Approach towards Rabies Elimination (SARE). In this article, we report a scoping review that we conducted to highlight the strengths, weaknesses, opportunities and threats as well as situational analysis of rabies control in Nigeria and suggest a timeline for key activities that are needed to ensure zero by 30. Our findings reveal that rabies is grossly under-reported as only 998 human and 273 dog-suspected rabies cases were reported across Nigeria between 2017 and 2022. Our literature review also demonstrates a paucity of information on rabies in both human and animal health sectors. A total of 49 studies on dog rabies in Nigeria, with a predominance of reports from the North Central geopolitical region (48%, n = 23) were therefore included in this study. Currently, only 16.2% (n = 6/37) of Nigerian states have available data related to the estimated dog populations, the dog ownership rates, the vaccination status of dogs or the incidence of dog bites. Based on a dog-to-human ratio of 1:16.3, we estimated that the dog population in Nigeria was 12,969,368 (95% CI: 12,320,900-13,617,836). Thus, to attain herd immunity and dog rabies control in Nigeria, at least 9.1 million dogs must be vaccinated annually. Our review reveals that, despite the strengths and available opportunities to achieve rabies control in Nigeria by 2030, the weaknesses and challenges will make the attainment of zero by 30 very difficult or impossible. Nigeria's best-case scenario by the year 2030 is SARE stage 3-4 (control-elimination) out of 5. Otherwise, the rabies control programme might not surpass SARE stages 2-3. To attain zero by 30, Nigeria must re-strategize its current rabies control programme by funding and implementing the national strategic plan for rabies control, creating a rabies desk office in the 37 states (FCT inclusive), rigorously conducting mass vaccination campaigns, providing post-exposure prophylaxis, prioritizing mass enlightenment with a focus on responsible pet ownership and conduct baseline national rabies surveillance in the animal and human health sectors.

BACKGROUND: Currently, over two million persons are internally displaced because of the complex humanitarian emergency in Nigeria's northeast region. Due to crowded and unsanitary living conditions, the risk of communicable disease transmission, morbidity, and mortality among this population is high. This study explored patterns and factors associated with health-seeking among internally displaced persons (IDPs) in northeast Nigeria to inform and strengthen disease surveillance and response activities. METHODS: In a cross-sectional study conducted during June-October 2022, we employed stratified sampling technique to select 2,373 IDPs from 12 IDPs camps. A semi-structured tool was used to collect data on health-seeking patterns, socio-demographics, households, and IDPs camps characteristics. We classified health-seeking patterns into three outcome categories: 'facility care' (reference category), 'non-facility care' (patent medicine vendors, chemists, traditional healers, religious centers), and 'home care/no care'. We performed complex survey data analysis and obtained weighted statistical estimates. Univariate analysis was conducted to describe respondents' characteristics and health-seeking patterns. We fitted weighted multivariable multinomial logistic regression models to identify factors associated with health-seeking patterns. RESULTS: Of 2,373 respondents, 71.8% were 18 to 39 years old, 78.1% were females, and 81.0% had no formal education. Among the respondents, 75.7% (95% CI: 72.9-78.6) sought 'facility care', 11.1% (95% CI: 9.1-13.1) sought 'non-facility care', while 13.2% (95% CI: 10.9-15.4) practiced 'home care/no care'. Respondents who perceived illness was severe (Adjusted Odds Ratio (AOR) = 0.15, [95% CI: 0.08-0.30]) and resided in officially-recognized camps (AOR = 0.26, [95% CI: 0.17-0.39]) were less likely to seek 'non-facility care' compared to 'facility care'. Similarly, respondents who resided in officially-recognized camps (AOR = 0.58, [95% CI: 0.36-0.92]), and received disease surveillance information (AOR = 0.42, [95% CI: 0.26-0.67) were less likely to practice 'home care/no care' rather than seek 'facility care'. CONCLUSIONS: This population exhibited heterogeneous patterns of health-seeking at facility and non-facility centers. Perception of illness severity and camps' status were major factors associated with health-seeking. To enhance surveillance, non-facility care providers should be systematically integrated into the surveillance network while ramping up risk communication to shape perception of illness severity, prioritizing unofficial camps.
RESUMO
The U.S. Centers for Disease Control and Prevention in collaboration with the National Malaria Elimination Program and the African Field Epidemiology Network established the Malaria Frontline Project to provide innovative approaches to improve the malaria program implementation in Kano and Zamfara States, Nigeria. Innovative approaches such as malaria bulletin, malaria monitoring wall chart, conduct of ward level data validation meetings and malaria dashboard have helped improve the use of data for decision making at all levels. Innovative approaches deployed during the project implementation facilitated data analysis and a better understanding of malaria program performance and data utilization for decision making at all levels. These innovative approaches may improve malaria control program performance in Nigeria and other resource limited countries.

BACKGROUND: Cholera, a diarrheal disease caused by the bacterium Vibrio cholerae, transmitted through fecal contamination of water or food remains an ever-present risk in many countries, especially where water supply, sanitation, food safety, and hygiene are inadequate. A cholera outbreak was reported in Bauchi State, North-eastern Nigeria. We investigated the outbreak to determine the extent and assess risk factors associated with the outbreak. METHODS: We conducted a descriptive analysis of suspected cholera cases to determine the fatality rate (CFR), attack rate (AR), and trends/patterns of the outbreak. We also conducted a 1:2 unmatched case-control study to assess risk factors amongst 110 confirmed cases and 220 uninfected individuals (controls). We defined a suspected case as any person > 5 years with acute watery diarrhea with/without vomiting; a confirmed case as any suspected case in which there was laboratory isolation of Vibrio cholerae O1 or O139 from the stool while control was any uninfected individual with close contact (same household) with a confirmed case. Children under 5 were not included in the case definition however, samples from this age group were collected where such symptoms had occurred and line-listed separately. Data were collected with an interviewer-administered questionnaire and analyzed using Epi-info and Microsoft excel for frequencies, proportions, bivariate and multivariate analysis at a 95% confidence interval. RESULTS: A total of 9725 cases were line-listed with a CFR of 0.3% in the state. Dass LGA had the highest CFR (14.3%) while Bauchi LGA recorded the highest AR of 1,830 cases per 100,000 persons. Factors significantly associated with cholera infection were attending social gatherings (aOR = 2.04, 95% CI = 1.16-3.59) and drinking unsafe water (aOR = 1.74, 95% CI = 1.07-2.83). CONCLUSION: Attending social gatherings and drinking unsafe water were risk factors for cholera infection. Public health actions included chlorination of wells and distribution of water guard (1% chlorine solution) bottles to households and public education on cholera prevention. We recommend the provision of safe drinking water by the government as well as improved sanitary and hygienic conditions for citizens of the state.

BACKGROUND: The Malaria Frontline Project (MFP) supported the National Malaria Elimination Program for effective program implementation in the high malaria-burden states of Kano and Zamfara adapting the National Stop Transmission of Polio (NSTOP) program elimination strategies. PROJECT IMPLEMENTATION: The MFP was implemented in 34 LGAs in the two states (20 out of 44 in Kano and all 14 in Zamfara). MFP developed training materials and job aids tailored to expected service delivery for primary and district health facilities and strengthened supportive supervision. Pre- and post-implementation assessments of intervention impacts were conducted in both states. RESULTS: A total of 158 (Kano:83; Zamfara:75) and 180 (Kano:100; Zamfara:80) healthcare workers (HCWs), were interviewed for pre-and post-implementation assessments, respectively. The proportions of HCWs with correct knowledge on diagnostic criteria were Kano: 97.5% to 92.0% and Zamfara: 94.7% to 98.8%; and knowledge of recommended first line treatment of uncomplicated malaria were Kano: 68.7% to 76.0% and Zamfara: 69.3% to 65.0%. The proportion of HCWs who adhered to national guidelines for malaria diagnosis and treatment increased in both states (Kano: 36.1% to 73.0%; Zamfara: 39.2% to 67.5%) and HCW knowledge to confirm malaria diagnosis slightly decreased in Kano State but increased in Zamfara State (Kano: 97.5% to 92.0%; Zamfara: 94.8% to 98.8%). HCWs knowledge of correct IPTp drug increased in both states (Kano: 81.9% to 94.0%; Zamfara: 85.3% to 97.5%). CONCLUSION: MFP was successfully implemented using tailored training materials, job aids, supportive supervision, and data use. The project strategy can likely be adapted to improve the effectiveness of malaria program implementation in other Nigerian states, and other malaria endemic countries.

This paper describes the process for developing, validating and disseminating through a train-the-trainer (TOT) event a standardised curriculum for public health capacity building for points of entry (POE) staff across the 15-member state Economic Community of West African States (ECOWAS) that reflects both international standards and national guidelines.A five-phase process was used in developing the curriculum: phase (1) assessment of existing materials developed by the US Centers for Disease Control and Prevention (CDC), Africa CDC and the West African Economic and Monetary Union, (2) design of retained and new, harmonised content, (3) validation by the national leadership to produce final content, (4) implementation of the harmonised curriculum during a regional TOT, and (5) evaluation of the curriculum.Of the nine modules assessed in English and French, the technical team agreed to retain six harmonised modules providing materials for 10 days of intensive training. Following the TOT, most participants (n=28/30, 93.3%) indicated that the International Health Regulations and emergency management modules were relevant to their work and 96.7% (n=29/30) reported that the training should be cascaded to POE staff in their countries.The ECOWAS harmonised POE curriculum provides a set of training materials and expectations for national port health and POE staff to use across the region. This initiative contributes to reducing the effort required by countries to identify emergency preparedness and response capacity-building tools for border health systems in the Member States in a highly connected region.

Population-based drug utilization studies are scanty in Nigeria. The aim was to determine the pattern and predictors of medication use among adults in the communities of Southwestern Nigeria. A cross-sectional study was conducted among adults selected by multi-stage sampling from Oyo State communities. The questionnaires, adapted from the WHO Students' Drug Use Questionnaire and previous studies, were pretested and interviewer administered. The respondents' socio-demographic characteristics, the pattern of medication use, prescribers, and sources of drug acquisition were obtained. Binary logistic regression was used to determine the predictor of medications used. Of the 999 respondents, 501 resided in rural communities while 498 dwelled in urban areas. The mean (±SD) age of the respondents was 38 ± 15 years. The median (range)% prevalence of medication use were as follows: lifetime use, 58.2 (17.7-81.0); current use, 31.2 (8.9-65.9); and past use, 20.3 (9.2-28.9). Medications were mainly obtained from patent medicine stores, median (range%), 71 (65-80). The commonly used drugs were paracetamol, 626 (67.6); nonsteroidal anti-inflammatory drugs, 174 (18.8); artemether/lumefantrine, 422 (68.2); ampicillin/cloxacillin, 220 (48.6); and chlorpheniramine, 59 (39.9). Factors predictive of current medication use, adjusted odd ratio (95% confidence interval) were as follows: antimalarial [male, 0.7 (0.5, 0.9)]; antibacterial [male, 0.6 (0.4-0.9)]; analgesics [married, 1.5 (1.1-2.2); presence of health facilities, 0.5 (0.3-0.7); and shorter distance to health facility, 1.5 (1.1-2.1)]. Antimalarials, antibacterial, and analgesics were commonly used and inappropriately obtained by adults in Southwestern Nigeria. Factors predictive of current medication use were gender, marital status, the presence of health facilities, and distance to health facilities. There is a need for more extensive countrywide medication use studies and enlightenment programs to ensure the appropriate use of medications.

Introduction: the Growing Expertise in E-health Knowledge and Skills (GEEKS) program is an applied apprenticeship program that aims to improve informatics capacity at various levels of the national health system and create a sustainable informatics workforce. Nigeria adapted the GEEKS model in 2019 as a mechanism to strengthen data quality and use of routine immunization (RI) and vaccine-preventable disease (VPD) surveillance data among Expanded Programme on Immunization (EPI) staff. Since the start of the GEEKS-EPI program, there has not been a formal assessment conducted to measure the extent to which GEEKS-EPI has been able to build local informatics workforce capacity and strengthen RI and VPD surveillance (VPDS) data quality and use in Nigeria. Methods: we conducted a qualitative assessment to inform the extent to which GEEKS-EPI has been able to build informatics skillsets to enhance local workforce capacity, foster collaboration across government agencies, and create a sustainable informatics workforce in Nigeria. In-Depth Interviews (IDIs) and Focus Group Discussions (FGDs) were held with GEEKS-EPI supervisors, mentors, and mentees from previous GEEKS-EPI cohorts. Results: while there were challenges reported during early implementation of the GEEKS-EPI program in Nigeria, particularly early on in the COVID-19 pandemic, participants and supervisors reported that the fellowship provided a framework for building a sustainable RI and VPDS informatics workforce through regular mentorship, peer-to-peer exchanges and Subject Matter Expert (SME)-led trainings. Conclusion: lessons learned from early implementation of GEEKS-EPI in Nigeria will help to inform its implementation in other countries, where strengthened national RI and VPDS informatics capacity is the primary objective.

Introduction: following the spread of the COVID-19 pandemic to Nigeria, the Federal Government of Nigeria restricted human and vehicular movements to curb the spread of the disease. This action had a negative impact on Acute Flaccid Paralysis (AFP) surveillance, with a resultant reduction in the number of AFP cases reported. This paper describes the impact of the COVID-19 pandemic on poliovirus surveillance in Nigeria and the proactive interventions by Nigeria´s polio program to mitigate the impact of COVID-19 on polio surveillance. Methods: nine innovative strategies were implemented in all 774 Local Government Areas (LGA) of the 36 states and Federal Capital Territory (FCT) of the country. These strategies were developed by the national surveillance officers and operationalized by sub-national surveillance officers with different strategies starting at different epidemiological weeks from week 14 to 23, 2020. Many of the strategy innovations were technology-based and included: the use of mobile phones to send the AFP case definition and video by WhatsApp or by SMS, the use of state-specific toll-free numbers and Mobile Telephone Network (MTN) (mobile service provider) CallerfeelTM to community informants (CI) who were the main targets of the interventions to increase case detection and reporting. Others included the use of abridged e-surveillance integrated supportive supervision (ISS) checklists, virtual monthly DSNO meetings, and batched AFP stool specimen transportation network. Results: compared to the same period in 2019, the cumulative rate of AFP case detection and reporting had gradually declined from 39.1% in January to 16.7% before the commencement of the interventions in week 20, 2020. However, the detection and reporting increased by 57.% from week 20 to week 47 compared to the same period in 2019. This is because with COVID-19, hospital visitation dropped, and the sick remained in the communities, so the CI network was relied on to detect and report AFP cases. The cumulative proportion of AFP cases reported by community informants as of week 47 increased from 13% in 2018 to 21% in 2020. This indicates an increase of 38%. Thirty-five AFP cases were detected and reported using the MTN Caller Feel strategy, while 15 cases were reported through state-specific toll-free numbers. Conclusion: the implementation of the innovative strategies was able to mitigate the low AFP case detection and reporting observed at the initial stage of the COVID-19 pandemic. The use of technology facilitated reaching the CI network, which was more instrumental in detecting and reporting the cases.

The Nigeria Polio Emergency Operations Centre (EOC) was established in October 2012 to strengthen coordination, provide strategic direction based on real-time data analysis, and manage all operational aspects of the polio eradication program. The establishment of seven state-level polio EOCs followed. With success achieved in the interruption of wild poliovirus (WPV) transmission as certified in 2020, the future direction of the polio EOC is under consideration. This paper describes the role of the polio EOC in other emergencies and perspectives on future disease control initiatives. A description of the functionality and operations of the polio EOC and a review of documentation of non-polio activities supported by the EOC was done. Key informant insights of national and state-level stakeholders were collected through an electronic questionnaire to determine their perspectives on the polio EOC's contributions and its future role in other public health interventions. The polio EOC structure is based on an incident management system with clear terms of reference and accountability and with full partner coordination. A decline in WPV1 cases was observed from 122 cases in 2012 to 0 in 2015; previously undetected transmission of WPV1 was confirmed in 2016 and all transmission was interrupted under the coordination of the EOCs at national and state levels. During 2014-2019, the polio EOC infrastructure and staff expertise were used to investigate and respond to outbreaks of Ebola, measles, yellow fever, and meningitis and to oversee maternal and neonatal tetanus elimination campaigns. The EOC structure at the national and state levels has contributed to the positive achievements in the polio eradication program in Nigeria and further in the coordination of other disease control and emergency response activities. The transition of the polio EOCs and their capacities to support other non-polio programs will contribute to harnessing the country's capacity for effective coordination of public health initiatives and disease outbreaks.

Introduction: event-based surveillance (EBS) is a surveillance method involving systematic and prompt data collection on incidents of public health importance, and complements the current indicator-based surveillance system and the Integrated Disease Surveillance and Response System (IDSR). It also promotes a rapid assessment and response to public health emergencies in Nigeria, although there is a lack of information regarding the status of EBS among Public Health Stakeholders in Nigeria; hence our study aimed to assess the awareness, availability, and utility of EBS among Nigerian public health stakeholders. Methods: we conducted a cross-sectional study to assess the awareness, availability, functionality, and utilization of EBS in the 36 States in Nigeria, plus the Federal Capital Territory (FCT). We interviewed 53 stakeholders in disease surveillance and response using a self-administered, semi-structured questionnaire to obtain responses on the awareness of the event-based surveillance system, availability, and functionality. We also assessed the common structures used to report health-related events and the availability of minimum requirements for an event-based surveillance system. We performed descriptive statistics for the data obtained. Results: the majority of respondents were males and 37.7% were disease surveillance and notification officers (DSNOs). Awareness of EBS was poor with about half, 49% of the respondents reported hearing of EBS, but only 17% described it correctly. The overall level of availability of the EBS reporting structure was inadequate, 28.2% and poorly utilised in the States. Conclusion: the awareness, availability, and utilization of event-based surveillance systems are low in Nigeria. The government should improve the feasibility and utility of EBS in the States to enhance early disease detection and response.

OBJECTIVE: Assessing the state of hypertension care remains the first step towards planning a robust health system needed to tackle the rising burden of hypertension. Prior to the commencement of the Community Action Against Non-Communicable Disease project, we assessed hypertension care using the hypertension care cascade (HCC). This will serve as a baseline to evaluate project performance upon completion. METHODS: Hypertensive subjects were grouped into a mutually exclusive care cascade of 5 categories including unscreened and undiagnosed; screened but undiagnosed; diagnosed but untreated; treated but uncontrolled and treated with controlled hypertension. RESULTS: Of the 372 participants, mean age 48.9 years, 161 (43.3%) were hypertensive, of whom only 12.0% had controlled blood pressure (BP). Among the 88.0% with uncontrolled BP,19.0% were unscreened and undiagnosed, 48.5% were screened but undiagnosed, 13.0% were diagnosed but untreated and 7.5% were treated but BP uncontrolled. The HCC demonstrates that 19% of the hypertensive patients were lost at the screening stage, 60% of those who were screened never diagnosed, 40% of those who were diagnosed did not receive treatment and 60% of those who were on treatment did not reach target BP. CONCLUSION: Unmet need of hypertension care is substantially high, thus underpinning the need for intervention with a multifaceted approach.

Objectives: To determine the birth prevalence, trend, and characteristics of external structural birth defects occurrence in Enugu Metropolis, Nigeria. Design: Cross-sectional study involving review of delivery records. Setting: The study was conducted at three tertiary hospitals, one public and two missionary, in Enugu Metropolis. Participants: Mothers and their babies delivered between 1 January 2009 and 31 December 2016 in the study facilities. Main outcome measures: Birth prevalence of defects presented as frequency/10,000 births. Other descriptive variables are presented as frequencies and percentages. Results: There were 21530 births with 133 birth defects (birth prevalence: 61.8/10,000 births) and 1176 stillbirths (stillbirth rate: 54.6/1000 births). The frequencies and birth prevalence (/10,000 births) of recorded defects were: Limb deformities 60(27.9), Neural tube defects (NTDs): 36(16.7), Urogenital system defects: 12(5.6), Gastrointestinal system defects 10(4.6) and Orofacial clefts 4(1.9). Birth defects occurrence showed a rising trend from 2009 to 2016. The mean (SD) age of mothers whose babies had Birth defects was 29.1(4.7) years. Only 62(46.6%) of 133 antenatal clinic folders of these women were traceable for further review. Eighteen (29.0%) had febrile illness in early pregnancy, 9(14.5%) had Malaria, 17(27.4%) had <4 antenatal clinic attendance, 7(11.3%) did not take folic acid and 6(9.7%) took herbal medications during pregnancy. Conclusions: Birth defects occurrence showed a rising trend with limb deformities and NTDs having the highest prevalence. Record keeping was poor at the facilities. Birth defects preventive interventions like folic acid supplementation for women-of-childbearing age should be promoted in Enugu Metropolis. Funding: This work was supported by the non-communicable disease Minigrant from the Task Force for Global Health, Decatur, Georgia, USA (TPN-FE-NCD-C2-IFO-9).

Globally, effective emergency response to disease outbreaks is usually affected by weak coordination. However, coordination using an incident management system (IMS) in line with a One Health approach involving human, environment, and animal health with collaborations between government and non-governmental agencies result in improved response outcome for zoonotic diseases such as Lassa fever (LF). We provide an overview of the 2019 LF outbreak response in Nigeria using the IMS and One Health approach. The response was coordinated via ten Emergency Operation Centre (EOC) response pillars. Cardinal response activities included activation of EOC, development of an incident action plan, deployment of One Health rapid response teams to support affected states, mid-outbreak review and after-action review meetings. Between 1st January and 29th December 2019, of the 5057 people tested for LF, 833 were confirmed positive from 23 States, across 86 Local Government Areas. Of the 833 confirmed cases, 650 (78%) were from hotspot States of Edo (36%), Ondo (26%) and Ebonyi (16%). Those in the age-group 21-40 years (47%) were mostly affected, with a male to female ratio of 1:1. Twenty healthcare workers were affected. Two LF naïve states Kebbi and Zamfara, reported confirmed cases for the first time during this period. The outbreak peaked earlier in the year compared to previous years, and the emergency phase of the outbreak was declared over by epidemiological week 17 based on low national threshold composite indicators over a period of six consecutive weeks. Multisectoral and multidisciplinary strategic One Health EOC coordination at all levels facilitated the swift containment of Nigeria's large LF outbreak in 2019. It is therefore imperative to embrace One Health approach embedded within the EOC to holistically address the increasing LF incidence in Nigeria.
RESUMO
Public Health Emergency Operations Centres (PHEOCs) provide a platform for multisectoral coordination and collaboration, to enhance the efficiency of outbreak response activities and enable the control of disease outbreaks. Over the last decade, PHEOCs have been introduced to address the gaps in outbreak response coordination. With its tropical climate, high population density and poor socioeconomic indicators, Nigeria experiences large outbreaks of infectious diseases annually. These outbreaks have led to mortality and negative economic impact as a result of large disparities in healthcare and poor coordination systems. Nigeria is a federal republic with a presidential system of government and a separation of powers among the three tiers of government which are the federal, state and local governments. There are 36 states in Nigeria, and as with other countries with a federal system of governance, each state in Nigeria has its budgets, priorities and constitutional authority for health sector interventions including the response to disease outbreaks. Following the establishment of a National PHEOC in 2017 to improve the coordination of public health emergencies, the Nigeria Centre for Disease Control began the establishment of State PHEOCs. Using a defined process, the establishment of State PHEOCs has led to improved coordination, coherence of thoughts among public health officials, government ownership, commitment and collaboration. This paper aims to share the experience and importance of establishing PHEOCs at national and subnational levels in Nigeria and the lessons learnt which can be used by other countries considering the use of PHEOCs in managing complex emergencies.

BACKGROUND: In disease control, the program officers are vital to the successful implementation of control strategies. However, poor knowledge of the disease and its control, staff attrition, and lack of intentional training for new staff can lead to under-performance and ineffectiveness of interventions. Thus, the Nigeria Field Epidemiology and Laboratory Training Program, in collaboration with National Malaria Elimination Program, planned a malaria short course (MSC) to strengthen the capacity of current program managers and incoming staff. To guide the development of the curriculum for the MSC, we conducted a needs assessment survey to ascertain the perceived usefulness of the MSC, the priority rating of MSC thematic domains and associated factors. METHODS: Overall, 384 purposively selected respondents across ten states and the Federal Capital Territory in Nigeria were interviewed. These comprised malaria and non-malaria control program staff at state, local government area (LGA) and ward levels. We administered a structured questionnaire to elicit information on socio-demographics, training needs, priority malaria thematic domains, perceived course usefulness and willingness of ministries/organizations to release staff to attend the MSC. Data were analyzed using descriptive and inferential statistics at p<0.05. RESULTS: Mean age was 43.9 (standard deviation: 7.6 years), 172 (44.8%) were females. Of the 384 respondents, 181 (47.1%), 144 (37.5%) and 59 (15.4%) were at the ward, LGA and state levels, respectively. Seventy-two (18.8%) had never worked in malaria control program. Majority (98.7%, n = 379) reported the need for further training, 382 (99.5%) opined that the course would be useful, and all affirmed their employers' willingness towards their participation at the training. Respondents rated high the domains of basic malariology, malaria treatment, malaria prevention, surveillance/data management, use of computers, leadership skills, program management and basic statistics. Predictors of malaria topical domains' high rating were gender (odds ratio (OR) = 6.77; 95% CI:3.55-12.93) and educational qualifications (OR = 0.48; 95% CI:0.26-0.89). CONCLUSIONS: A malaria short course is a necessity and appropriate for program officers at different levels of health administration in Nigeria to achieve malaria elimination, taking into consideration the challenges of human resource retention. The outcome of this study should inform the curriculum and the delivery of the MSC.

Free movement between countries without a visa is allowed within the 15-country Economic Community of West African States (ECOWAS) region. However, little information is available across the region on the International Health Regulation (IHR 2005) capacities at points of entry (PoE) to detect and respond appropriately to public health emergencies such as Coronavirus Disease 2019 (COVID-19). ECOWAS and the member states can better tailor border health measures across the region by understanding public health strengths and priorities for improvement at PoEs. A comprehensive literature review was combined with a self-assessment of capacities at PoEs across the fifteen member states from February to July 2020. For the assessment, the member states completed an adapted World Health Organization (WHO) self-assessment checklist by classifying capacity for seven domains as fully, partially, or not implemented. The team implemented three focus group discussion (FGD) sessions and 13 key informant interviews (KII) with national-level border health stakeholders. Univariate analysis was used to summarize the assessment data and detailed content analysis was applied to evaluate FGD and KII results. Of the 15 member states, 3 (20%) are landlocked; 3 (20%) have more than one seaport. Eleven (73%) countries have 1 designated airport, 3 (20%) have two airports, and only one country (6.7%) has three airports. Two hundred and seventy-eight designated ground crossings were identified in 12 countries (80%). Strengths across the PoE were existence of decrees and ministerial acts in some ECOWAS countries and establishment of national taskforces for the COVID-19 response at PoE in ECOWAS. Major challenges were porous borders, poor intersectoral coordination, lack of harmonized traveler screening measures, shortage of staff, and inadequate financial resources. Despite all these challenges, there are opportunities such as leveraging the regional cross-border poliomyelitis coordination and control mechanism, and existence of networks of infection prevention and control specialists and field epidemiologists. However, political instabilities in some countries pose a threat to government commitments to PoE activities. The capacity to respond to public health emergencies at PoE in the ECOWAS region is still below IHR standard. Public health capacities at a majority of IHR-designated PoE in the 15-country region do not meet required core capacities standards.

INTRODUCTION: intestinal parasitic infection has been reported as a cause of morbidity and mortality among HIV patients on antiretroviral therapy (ART) due to interruption in treatment of the defaulting HIV patients. This study aimed to determine the prevalence and possible causes of intestinal parasites among HIV patients on ART. METHODS: a survey involving 375 adult HIV/AIDS patients selected using a systematic random sampling technique was conducted in a Jos University Teaching hospital, Plateau State, Nigeria. Socio-demographic and clinical data was collected using semi-structured interviewer administered questionnaire and electronic dataset review. Fresh stool samples were collected from all participants for laboratory identification of intestinal parasites using formol-ether sedimentation and modified Ziehl-Neelsen techniques. Descriptive statistics, odds ratio and logistic regression model were computed at P ≤ 0.05. RESULTS: the mean age of the study participants was 41.6±9.3years. Majority 294 (78.4%) were females, 141 (37.6%) lived in the rural area, 50 (13.3%) respondents did not have toilets in their homes. Most 275 (73.3%) had ART adherence level of 95% and above. Prevalence of intestinal parasites was 28.5%. Females (aOR = 2.14, 95% CI=1.12 - 3.89) and participants with no toilet facilities (aOR = 2.0, 95% CI=1.03 - 3.94) were significantly more likely to have intestinal parasites. CONCLUSION: the prevalence of intestinal parasites was high among HIV patients. Gender and unavailability of toilet in homes were found to be predictors of having parasites. We recommend that HIV patients should be periodically screened for IPs during the follow-up clinic visits.
