The Lagos State COVID-19 Think-tank, a Potential Framework for Decision-making in a Pandemic Era.

Lagos state remains the epicenter of COVID-19 infection in Nigeria. To facilitate the emergency preparedness and response to COVID-19, the State Governor and Incident Commander constituted a Think Tank comprising 13 experts from various disciplines committed to the health of the public. The Think Tank assisted the government with decision-making strategies and supported the emergency operation centre (EOC) for the COVID-19 response. Their main achievements were developing frameworks for decision-making and strategies for phased easing of the State-wide lockdown. The challenges encountered were that it was often viewed as a parallel structure to the EOC and separated from the traditional civil service structure; causing some reluctance to implement ideas generated by the Think Tank. Nevertheless, the Think Tank played an important role during the COVID-19 pandemic; the lessons learned might help other states and resource-limited countries wishing to adopt this approach to emergency response.

RésuméL'État de Lagos reste l'épicentre de l'infection au COVID-19 au Nigeria. Pour faciliter la préparation et la réponse aux situations d'urgence (EPR) face au COVID-19, le gouverneur de l'État a constitué un groupe de réflexion composé de 13 experts de diverses disciplines. Le concept du groupe de réflexion était d'impliquer le secteur privé et le milieu universitaire dans la réponse COVID de l'État de Lagos, reconnaissant qu'un résultat réussi de l'EPR nécessite une expertise dont certaines n'existaient pas au sein de la fonction publique. Le Think Tank a aidé le gouvernement à élaborer des stratégies de prise de décision et a soutenu le centre des opérations d'urgence (COU) pour la réponse à la COVID-19. Leurs principales réalisations ont été l'élaboration de cadres de prise de décision et de stratégies d'assouplissement progressif du confinement à l'échelle de l'État. Les défis rencontrés étaient qu'il était souvent considéré comme une structure parallèle à l'EOC et séparé de la structure traditionnelle de la fonction publique; provoquant une certaine réticence à mettre en œuvre les idées générées. Le groupe de réflexion de l'État de Lagos a démontré un modèle réussi de partenariat public-privé dans le domaine de la santé mis en œuvre par une diversité d'acteurs dans des secteurs critiques. Cela pourrait être considéré comme un modèle utile pour faire face à une myriade de crises similaires auxquelles le secteur de la santé est souvent confronté. Les enseignements tirés pourraient aider d'autres États et pays aux ressources limitées souhaitant adopter cette approche dans les interventions d'urgence.

Establishing event-based surveillance system in Nigeria: a complementary information generating platform for improved public health performance, 2016.

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.

The One Health approach to incident management of the 2019 Lassa fever outbreak response in Nigeria.

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.

Measures to control protracted large Lassa fever outbreak in Nigeria, 1 January to 28 April 2019.

Lassa fever cases have increased in Nigeria since 2016 with the highest number, 633 cases, reported in 2018. From 1 January to 28 April 2019, 554 laboratory-confirmed cases including 124 deaths were reported in 21 states in Nigeria. A public health emergency was declared on 22 January by the Nigeria Centre for Disease Control. We describe the various outbreak responses that have been implemented, including establishment of emergency thresholds and guidelines for case management.

Large Outbreak of Neisseria meningitidis Serogroup C - Nigeria, December 2016-June 2017.

On February 16, 2017, the Ministry of Health in Zamfara State, in northwestern Nigeria, notified the Nigeria Centre for Disease Control (NCDC) of an increased number of suspected cerebrospinal meningitis (meningitis) cases reported from four local government areas (LGAs). Meningitis cases were subsequently also reported from Katsina, Kebbi, Niger, and Sokoto states, all of which share borders with Zamfara State, and from Yobe State in northeastern Nigeria. On April 3, 2017, NCDC activated an Emergency Operations Center (EOC) to coordinate rapid development and implementation of a national meningitis emergency outbreak response plan. After the outbreak was reported, surveillance activities for meningitis cases were enhanced, including retrospective searches for previously unreported cases, implementation of intensified new case finding, and strengthened laboratory confirmation. A total of 14,518 suspected meningitis cases were reported for the period December 13, 2016-June 15, 2017. Among 1,339 cases with laboratory testing, 433 (32%) were positive for bacterial pathogens, including 358 (82.7%) confirmed cases of Neisseria meningitidis serogroup C. In response, approximately 2.1 million persons aged 2-29 years were vaccinated with meningococcal serogroup C-containing vaccines in Katsina, Sokoto, Yobe, and Zamfara states during April-May 2017. The outbreak was declared over on June 15, 2017, after high-quality surveillance yielded no evidence of outbreak-linked cases for 2 consecutive weeks. Routine high-quality surveillance, including a strong laboratory system to test specimens from persons with suspected meningitis, is critical to rapidly detect and confirm future outbreaks and inform decisions regarding response vaccination.
