Pattern and predictors of medication use among adults in southwestern Nigeria: A community-based cross-sectional study.

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.

COVID-19 pandemic waves: how prepared is West Africa for managing a high COVID-19 caseload? Urgent actions needed.

The ECOWAS Region and the world have learnt a lot in the last year and a half concerning the pandemic. As the pandemic continues to evolve, the region needs to put together all these lessons in other to better protect its people, rebuild its economy and strengthen the regional health security for better regional prosperity. We reviewed the response mounted by the region from January 2020 to July 2021 and the existing body of knowledge. We recommend that the region quickly increase the COVID-19 immunization coverage, sustain the enhance genomic surveillance, improve testing and the strengthen point of entry surveillance.

Revelation of an important weakness in polio elimination efforts in Nigeria: a descriptive cross-sectional study of nomadic dynamics in Sokoto and Taraba States, May 2013.

Introduction: Operational gaps in the Global Polio Eradication Initiative implementation had been partly responsible for inadequate population immunity and the continued transmission of wild poliovirus in Nigeria before the African Region was declared polio-free in 2020. Missed opportunities to provide services in nomadic populations due to frequent mobility, lack of inclusion in microplans and the remoteness of their settlements were the major challenges. During May 2013 we conducted immunization outreach to nomadic and other underserved communities in Rabah LGA, Sokoto state, and Ardo Kola LGA, Taraba state, in Nigeria to identify and vaccinate children missed during supplemental immunization activities while identifying missed acute flaccid paralysis cases. Methods: An enumeration checklist and data collection instruments on Android cell phones were used to capture socio-demographic data and GPS coordinates on nomadic settlements, households, number of children aged <5 years, children previously missed for vaccination and their locations. Local guides led trained enumerators to underserved communities for the enumeration and vaccination. Data were analyzed using Microsoft Excel 2007. Results: A total of 324 settlements were listed for the two states, and 111 (34.3%) of these were identified as missed when compared with micro-planning for the most recent SIA. In these settlements, 3,533 households and 9,385 children aged <5 years were listed. We administered oral poliovirus vaccine to all 1,946 missed children during the recent or any supplemental immunization activities. Of these, 527 (27.1%) had never been vaccinated. We found no missed acute flaccid paralysis cases. Conclusion: Nomadic populations continue to be underserved, especially for vaccination services. This results in pockets of populations with low herd immunity and increased risk for poliovirus transmission. Community leaders and nomadic settlements should be included in the micro-planning of all supplemental immunization activities to ensure all children receive vaccination services.

National Stop Transmission of Polio Program support for polio supplemental immunization activities in Nigeria 2012-2016: deployment of management support team.

Introduction: to support polio eradication activities in Nigeria, in 2012 the National Polio Emergency Operation Center (NEOC) created the Management Support Teams (MST) to address gaps in the quality of supervision of polio vaccination teams. The National Stop Transmission of Polio (NSTOP) Program supported the polio eradication activities by deploying trained supervisors as part of the MST for polio and non-polio immunization campaigns. Methods: trained MST members were deployed approximately 4 days before the start of the campaign to participate in pre-implementation activities and supervise vaccination teams during campaigns. Terms of reference (TOR) developed by NEOC was provided to MST members to guide their activities. Qualified MSTs that met pre-determined criteria were selected and deployed to the field to support pre, intra and post campaigns activities. Results: a pool of over 400 MST personnel have been identified, trained, and repeatedly deployed from 2012 till 2016. The number of deployed MST personnel rose from 40 per campaign in October 2012 to 342 in May 2016. Of these, 270 (79%) MST personnel were deployed to 11 polio high-risk states of northern Nigeria, where campaigns are conducted between eight and ten times yearly as planned by NEOC. For measles campaigns, about 300 (75%) MST personnel were deployed for the one-off northern and southern campaigns in 2016. The results of clustered Lot Quality Assurance Sampling (LQAS) post-campaign vaccination coverage surveys, a measure of campaign quality, of which introduction into the polio program coincided with deployment of MSTs, showed improvement over time, from 10% (very poor quality) in February 2012 to about 90% (good quality) in December 2016. Conclusion: the deployment of MST personnel increased the number of trained supervisors in the field, frequency of supervisory visits and had a positive impact on the quality of polio campaigns.

Targeted Short Message Service-Based Intervention to Improve Routine Immunization Reporting in Bauchi State, Nigeria, 2016.

Introduction: High quality, timely and complete immunization data are essential for program planning and decision-making. In Nigeria, the National Health Management Information System (NHMIS) Routine Immunization (RI) module and dashboard (on the District Health Information System version 2 (DHIS2) platform) support the use of real time RI data. We deployed an automated short message service (SMS) notification system that works with the existing RI module to facilitate improvements in RI data in the DHIS2. Methods: A pilot project was performed using intervention and control local government areas (LGAs). A mixed methods approach using both qualitative and quantitative methods was used to evaluate the system. We assessed changes in reporting rates across different reports. The evaluation also included baseline and post-intervention surveys of health facility (HF) staff. Results: Reporting timeliness (76% pre and 99% post intervention) and completeness (83% pre and 99% post intervention) were consistently higher during the post-intervention than the pre-intervention period for facilities in the intervention LGA while reporting timeliness (65% pre and 66% post intervention) and completeness (71% and 77% post intervention) for facilities in the control LGA showed no change. Users reported that the SMS system was easy to understand and helped to facilitate improvements in consistency of data and timeliness of reporting. Inability of health care workers to effect changes at the HF level and the lack of immediate feedback were reported as key challenges to timeliness and quality of reports. Conclusion: An SMS-based intervention improved timeliness and completeness of health data reporting. However, the intervention should be evaluated on a larger scale over a longer time period before considering a national implementation.

Strengthening Applied Epidemiology in West Africa: Progress, Gaps, and Advancing a Regional Strategy to Improve Health Security.

The ability to prevent, promptly detect, and appropriately respond to a public health threat is essential for health security. Field epidemiology training has helped increase the quality and quantity of the public health workforce to strengthen disease surveillance, outbreak preparedness and response, and general public health capacity. We conducted a desk review on the status of the Field Epidemiology and Laboratory Training Program model in 16 countries in West Africa. We also developed a questionnaire and shared it with West African Health Organization (WAHO) member states to document their experiences and the status of training in their countries. WAHO organized a regional 3-day consultative meeting with major stakeholders in the region to examine progress, gaps, and challenges, and outline a roadmap to strengthen the Field Epidemiology and Laboratory Training Program. Stakeholders shared their experiences, engaged in discussions to identify strengths and gaps, and made plans on a way forward. Member states are at different levels of implementing field epidemiology and laboratory training programs in their countries, and, therefore, major gaps remain in the number and distribution of trained epidemiologists throughout West Africa. Member states implement different variants of the program and in some instances the same cadre of health workers are trained in different but comparable programs with different funding streams. Two member states had not begun implementing the training program. Developing regional centers of excellence was recommended in the long term while collaboration among member states to train the required number of epidemiologists to fill the acute needs could be helpful in the short and medium term. Curriculum harmonization and expansion, deployment and use of trained epidemiologists, accreditation of training institutions, and generation of indigenous funding streams are recommended to improve the Field Epidemiology and Laboratory Training Program in West Africa.

Improving Cross-Border Preparedness and Response: Lessons Learned from 3 Lassa Fever Outbreaks Across Benin, Nigeria, and Togo, 2017-2019.

Long-standing cultural, economic, and political relationships among Benin, Nigeria, and Togo contribute to the complexity of their cross-border connectivity. The associated human movement increases the risk of international spread of communicable disease. The Benin and Togo ministries of health and the Nigeria Centre for Disease Control, in collaboration with the Abidjan Lagos Corridor Organization (a 5-country intergovernmental organization) and the US Centers for Disease Control and Prevention, sought to minimize the risk of cross-border outbreaks by defining and implementing procedures for binational and multinational public health collaboration. Through 2 multinational meetings, regular district-level binational meetings, and fieldwork to characterize population movement and connectivity patterns, the countries improved cross-border public health coordination. Across 3 sequential cross-border Lassa fever outbreaks identified in Benin or Togo between February 2017 and March 2019, the 3 countries improved their collection and sharing of patients' cross-border travel histories, shortened the time between case identification and cross-border information sharing, and streamlined multinational coordination during response efforts. Notably, they refined collaborative efforts using lessons learned from the January to March 2018 Benin outbreak, which had a 100% case fatality rate among the 5 laboratory-confirmed cases, 3 of whom migrated from Nigeria across porous borders when ill. Aligning countries' expectations for sharing public health information would assist in reducing the international spread of communicable diseases by facilitating coordinated preparedness and responses strategies. Additionally, these binational and multinational strategies could be made more effective by tailoring them to the unique cultural connections and population movement patterns in the region.

Coverage of indoor residual spraying for malaria control and factors associated with its acceptability in Nasarawa State, North-Central Nigeria.

INTRODUCTION: Indoor residual spraying (IRS) is among the major vector control strategies recommended for endemic populations by the World Health Organization (WHO). The success of IRS requires high coverage which is dependent on its acceptability. In Nigeria, IRS pilots have been ongoing and rejection has been a major setback to its coverage. We assessed coverage of IRS and determined factors associated with its acceptability in Nasarawa Eggon district, Nasarawa state, Nigeria. METHODS: A cross-sectional survey involving 409 households selected using multi-stage sampling was carried out. Trained data collectors administered pre-tested structured questionnaire to collect data on socio-demographic characteristics of household heads or their representatives, their perceptions on IRS and factors associated with IRS acceptability. Descriptive, bivariate and multivariate analyses were done at 5% level of significance. RESULTS: Majority of respondents were male (79.7%) and married (82.6%), and their mean age was 36.4 ± 13.3 years. Coverage of IRS was 99.3%. However, only 82.6% of those who previously accepted IRS were willing to accept it in again. Factors independently associated with acceptability were perceived effectiveness of IRS (aOR = 21.8; 95%CI = 6.9-68.8) and lower household cost of malaria prevention after IRS (aOR = 5.0; 95%CI = 1.1-21.8). CONCLUSION: IRS coverage in the communities studied met WHO minimum standard of 85%. However, for similar results to be achieved in future, acceptability must be promoted by providing information on its effectiveness and its ability to reduce household cost of malaria prevention.

Socio-demographic and regional disparities in utilization of intermittent preventive treatment for malaria in pregnancy - Nigeria demographic health survey 2013.

INTRODUCTION: malaria in pregnancy can lead to medical emergencies. Utilization of intermittent preventive treatment for prevention of malaria in pregnancy with Sulphadoxine- Pyrimethamine (IPTp-SP) has remained low in developing countries in sub-Saharan Africa. This study aimed to identify the factors determining uptake of IPTp-SP in Nigeria using the 2013 Nigeria Demographic Health Survey. METHODS: we conducted a secondary analysis of data extracted from the National Demographic Health Survey 2013 which used a three stage stratified sampling method to select respondents. Independent variables considered were age, marital status, the level of education of respondents and their spouses, region, location of residence, wealth-index and birth order. The dependent variable was the use of two or more doses of SP for IPTp in the two years before the survey. Descriptive statistics for socio-demographic and selected characteristics was done. Chi-square test was used to test associations between sociodemographic characteristics and IPTp-SP uptake. Multiple logistic regressions at 95% confidence interval were used to determine predictors of IPTp utilization using STATA version14 software. RESULTS: of the 38,948 women interviewed 12,473 (32%) had given birth two years preceding the survey and 15% used at least two doses of SP for IPTp. Women aged 30 years and above [aOR 1.4, C.I:1.1-1.7], in the middle class or higher wealth index [aOR 1.5, CI: 1.1-2.0], with two or more ANC visits [aOR 4.2, CI: 1.4 - 12.5], were more likely to use IPTp. CONCLUSION: late initiation of IPTp after the second trimester was a contributory factor for poor SP utilization. Interventions targeted at ensuring pregnant women attend ANC and use of IPTp-SP after quickening should be promoted.

Trends in mortality at Federal Medical Centre, Owo, Ondo State, Nigeria 2006-2014.

INTRODUCTION: vital events registration is not accurately done in Nigeria. Hence, mortality data is often not available. Health facility-based data can provide useful information on the trends in mortality of a population. This study describes the trend of deaths in a tertiary health facility. METHODS: a retrospective review of the medical records of all patients that died in the Federal Medical Centre, Owo, Ondo State, Nigeria from 2006 to 2014 was conducted. Data extracted from the records included age, sex, primary cause of death and date of admission and death. Frequencies were done and the median age of male and female deaths were compared using Mann-Whitney U test. RESULTS: a total of 1,326 deaths occurred in the hospital. The median age at death was 46 years (range: 0-110), median age was 49 years in males and 43 years in females (p = 0.025). One fifth (20.9%) of deaths was in infants. The median length of hospital stay was 4 days (range: 0-277). The highest proportion of death (16.4%) was in 2009 and on Wednesdays (15.9%). More deaths occurred in January (11.5%) and (10.3%) in February than in other months. The leading cause of communicable disease death in age 1 and above were HIV (15.2%) and TB (2.5%). Birth asphyxia (39.3%) and low birth weight (46%) were the commonest cause of death in infants. CONCLUSION: over the years the leading causes of mortality were preventable. Infant mortality remains a public health problem. Hospital mortality data could guide health decision making and interventions in Nigeria. Interventions to reduce death from communicable diseases and in infants are urgently recommended.

Burden of measles in Nigeria: a five-year review of casebased surveillance data, 2012-2016.

INTRODUCTION: measles is a vaccine preventable, highly transmissible viral infection that affects mostly children under five years. We reviewed surveillance data on measles from Nigeria over a five-year period to highlights its burden and make recommendations for improvements. METHODS: we conducted a secondary data analysis of measles specific Integrated Disease Surveillance and Response (IDSR) records of all states in Nigeria over a five-year period. RESULTS: a total of 131,732 cases were recorded between January 2012 and September 2016. Most cases 57,892 (43.95%) were recorded in 2013 while the least 11,061 (8.4%) were recorded in 2012. A total of 817 deaths were recorded, with a case fatality rate (CFR) of 0.62%. The highest CFR (1.43%) was recorded in 2012 while the least CFR (0.44%) was recorded in 2016. Only 8,916 (6.7%) cases were confirmed by laboratory tests. The trend of measles cases followed the same pattern throughout the years under review, with cases peaking at March, then gradually reducing to lowest level at June, which was maintained throughout the rest of the year. States in northern region of Nigeria recorded the highest attack rate (Yobe: 480.29 cases per 100,000 population, Sokoto: 284.63 cases per 100,000 population and Katsina: 246.07 cases per 100,000 population) compared to States in the southern region (Rivers: 11.72 cases per 100,000 population and Akwa Ibom: 13.59 cases per 100,000 population). Conversely, States in the southern region recorded the highest CFR (Ebonyi: 13.43% and Rivers: 3.27%). CONCLUSION: measles infection remains a burden especially in the northern region of Nigeria. Although measles fatalities declined over the years, laboratory confirmation was sub-optimal. We recommended improvement on routine immunization and strengthening of regional laboratories diagnostic capacities, for successful eradication of measles from Nigeria.

Blood donor safety, prevalence and associated factors for cytomegalovirus infection among blood donors in Minna-Nigeria, 2014.

INTRODUCTION: human cytomegalovirus (CMV) has remained a cause of morbidity and mortality in pregnancy and immunocompromised patients. CMV is transmissible through blood transfusion. We conducted a descriptive, cross-sectional study to assess blood donor safety and to determine the prevalence and associated factors for CMV infection among blood donors in Minna, Nigeria. METHODS: all consenting blood donors were screened for CMV antibodies (IgM and IgG) using ELISA kit and haematological indices using a haematological analyzer. We administered structured questionnaires to obtain socio-demographic and socio-economic data. Data were subjected to univariate, bivariate and multivariate statistical analyses using Epi Info version 3.5.4. Significant associations were presumed if p < 0.05. RESULTS: a total of 345 participantswere recruited, the majority were males 336 (97.4%). Monthly earnings of majority of the blood donors, 136 (40.6%) ranged from ₦18,000 to ₦35,000. The prevalence of CMV infection was 96.2%. The prevalence of anti-CMV IgG antibodies was 96.2% and that of IgM was 2.6%. Most of the study participants, 274 (79.4%) were family replacement donors. The majority of the blood donors 195 (56.5%) were anaemic (PCV < 36, Hb < 12g/dl). Those with positive CMV were more likely to be of high-income level (OR = 0.32, P = 0.04). CONCLUSION: the seroprevalence of CMV was high with a significant proportion of donors capable of transmitting CMV infection to blood recipients. The majority of the blood donors were anaemic. High income level is associated with CMV infection. Quality of screening for anemia be improved.

Trend of malaria cases in Kaduna State using routine surveillance data, 2011-2015.

INTRODUCTION: in 2015, 212 million malaria cases and 429,000 malaria deaths were estimated globally. Kaduna State, located in northern Nigeria had a malaria prevalence rate of 36.7% among children less than 5 years old which was higher than the national average of 27%. We assessed the trend of malaria cases in Kaduna State from 2011 to 2015, to analyse trend of malaria in Kaduna as well as describe malaria in time, place and person. METHODS: we conducted secondary data analysis of Kaduna State malaria data between January 2011 and December 2015. Data were extracted from the Integrated Disease Surveillance and Response (IDSR) 003 form. Data of uncomplicated malaria defined as "any person with fever or history of fever within 24 hours; without signs of severe disease (vital organ dysfunction)" was analysed. In IDSR, a case of malaria is based on presumed diagnosis. Frequencies and proportions were calculated. We also conducted trend analysis of incidence of malaria. RESULTS: in the period under study, 1,031,603 malaria cases were recorded with 238 deaths (CFR = 0.23 per 1,000). There was a downward trend with a slope of -3287.2. The data showed higher seasonal variation for quarters 2 (1430.96) and 3 (Q2 = 6,460.23) compared to Quarters 1 (6,857.19) and 4 (-1,034.01). Overall, the age group 12 -59 months had the highest number of incident cases 225, 537 (20.3%). Malaria death was highest in children 1 to 11 months (26.5%) and least, in children 0 -28 days (2.5%). CFR was also highest in children 1 to 11 months (0.45 per 1,000). The highest incidence of malaria cases was in Jaba Local Government Area (47.7%) and the least, in Lere (2.4%). CONCLUSION: there was a decreased incidence of malaria from 2011 to 2015. Malaria was most common in the second and third quarters of each year. Age group 12-59 months was most affected. Kaduna State Malaria Programme should sustain the programs it is implementing and focus more on the under-five years age group.

Strengthening service integration for effective linkage of HIV-positive mothers to antiretroviral treatment: a cross-sectional study in two military health facilities in Kaduna, Nigeria, 2014.

INTRODUCTION: strong PMTCT-ART service linkages ensure continuity of care for healthier mothers and children born HIV free. Program data showed weak PMTCT- ART linkages in military health facilities. We conducted a study to assess the PMTCT-adult ART service linkage in two Nigerian military health facilities in Kaduna State. METHODS: we conducted a cross-sectional study using mixed methods (interviews and FGDs) in 44 Nigeria Army Reference Hospital (NARH) and 1 Division Hospital, Kaduna. We studied 372 HIV-positive mothers after a delivery of their babies, referred for ART services from January 2009 to December 2013. We conducted FGDs among ANC, PMTCT and ART clinics staff. We analysed data using descriptive and inferential methods. A p-value of < 0.05 was considered significant with 95% confidence intervals (CI) for estimates. RESULTS: of the 372 respondents studied, 320 (86%) accessed PMTCT services from the 44 NARH. Most respondents (206,55.4%) respondents aged < 25 years. One in six (16.7%) respondents had no record of referral. Delivering baby in a separate facility from where PMTCT services were accessed, increased the likelihood of not accessing ART services (odd ratio [OR]: 6.7, 95% CI= 3.3 -13.6). The qualitative study identified poor service integration between PMTCT and ANC clinics. CONCLUSION: the key factors hindering PMTCT-ART linkage in military health facilities included poor service integration, clients delivering of a baby in a facility separate from where PMTCT services were accessed. The Ministry of Defence HIV programme should strengthen ANC-PMTCT-ART service integration through a centrally coordinated client information management system.

Assessing the Concepts and Designs of 58 Mobile Apps for the Management of the 2014-2015 West Africa Ebola Outbreak: Systematic Review.

BACKGROUND: The use of mobile phone information technology (IT) in the health sector has received much attention especially during the 2014-2015 Ebola virus disease (EVD) outbreak. mHealth can be attributed to a major improvement in EVD control, but there lacks an overview of what kinds of tools were available and used based on the functionalities they offer. OBJECTIVE: We aimed to conduct a systematic review of mHealth tools in the context of the recent EVD outbreak to identify the most promising approaches and guide further mHealth developments for infectious disease control. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched for all reports on mHealth tools developed in the context of the 2014-2015 EVD outbreak published between January 1, 2014 and December 31, 2015 on Google Scholar, MEDLINE, CAB Abstracts (Global Health), POPLINE, and Web of Science in any language using the search strategy: ("outbreak" OR "epidemic") AND ("mobile phone" OR "smartphone" OR "smart phone" OR "mobile phone" OR "tablet" OR "mHealth") AND ("Ebola" OR "EVD" OR "VHF" OR "Ebola virus disease" OR "viral hemorrhagic fever") AND ("2014" OR "2015"). The relevant publications were selected by 2 independent reviewers who applied a standardized data extraction form on the tools' functionalities. RESULTS: We identified 1220 publications through the search strategy, of which 6.31% (77/1220) were original publications reporting on 58 specific mHealth tools in the context of the EVD outbreak. Of these, 62% (34/55) offered functionalities for surveillance, 22% (10/45) for case management, 18% (7/38) for contact tracing, and 6% (3/51) for laboratory data management. Only 3 tools, namely Community Care, Sense Ebola Followup, and Surveillance and Outbreak Response Management and Analysis System supported all four of these functionalities. CONCLUSIONS: Among the 58 identified tools related to EVD management in 2014 and 2015, only 3 appeared to contain all 4 key functionalities relevant for the response to EVD outbreaks and may be most promising for further development.

Mortality Among Confirmed Lassa Fever Cases During the 2015-2016 Outbreak in Nigeria.

OBJECTIVES: To determine factors associated with mortality among confirmed Lassa fever cases. METHODS: We reviewed line lists and clinical records of laboratory-confirmed cases of Lassa fever during the 2016 outbreak in Nigeria to determine factors associated with mortality. We activated an incident command system to coordinate response. RESULTS: We documented 47 cases, 28 of whom died (case fatality rate [CFR] = 59.6%; mean age 31.4 years; SD = ±18.4 years). The youngest and the oldest were the most likely to die, with 100% mortality in those aged 5 years or younger and those aged 55 years or older. Patients who commenced ribavirin were more likely to survive (odds ratio [OR] = 0.1; 95% confidence interval [CI] = 0.03, 0.50). Fatality rates went from 100% (wave 1) through 69% (wave 2) to 31% (wave 3; χ2 for linear trend: P < .01). Patients admitted to a health care center before incident command system activation were more likely to die (OR = 4.4; 95% CI = 1.1, 17.6). The only pregnant patient in the study died postpartum. CONCLUSIONS: Effective, coordinated response reduces mortality from public health events. Attention to vulnerable groups during disasters is essential. Public Health Implications. Activating an incident command system improves the outcome of disasters in resource-constrained settings.

Response to an unusual outbreak in a high-risk situation.

In 2010, a series of lead poisoning outbreaks linked to artisanal gold processing killed at least 400 young children in Zamfara State in northwestern Nigeria. There were several efforts to respond to the outbreaks as they occurred. Subsequent recurrence of lead poisoning outbreaks within Zamfara and beyond suggested that there were no efforts to mitigate the outbreaks as recommended for disaster management. This case study, to be completed within 3 hours, is suitable for senior level public health officials and those training for such positions. It enables participants to review and apply epidemiological principles for managing disasters and suggest steps toward development of policy recommendations based on the context of environmental lead exposure. It will serve as a generic training module for managers/responders of other natural (floods, heat stroke) and man-made disasters (civil strife, conflict, insurgency) based on the general/standard principle of the complete disaster management cycle.

Contact tracing following outbreak of Ebola virus disease in urban settings in Nigeria.

An outbreak of Ebola virus disease occurred in Nigeria between July and September 2014. Contact tracing commenced in Lagos, and extended to Port Harcourt and Enugu as the outbreak continued to spread. A total of 899 contacts were traced. Contact tracing enhanced immediate identification of symptomatic contacts, some of whom eventually became cases. Contact tracing could be challenging in urban cities. However, use of electronic technology, adequate logistics, and highly skilled personnel enhanced the tracing of contacts to facilitate the successful containment of the outbreak. Nigeria was certified to be Ebola free on 21st October 2014. Ebola virus surveillance needs to be maintained to ensure the disease has been contained and to prevent future outbreaks. This case study aims to help trainees to review concepts, apply skills, and address challenges for contact tracing based on the experience of the Nigerian Field Epidemiology Training Network during the 2014 Ebola virus disease outbreak.
