  • Implementing public health emergency operations centres according to an international framework in Ethiopia, Nigeria, and Senegal

    Open Access•Senait Tekeste Fekadu, Jian Li et al.•ARTICLE•PLOS Global Public Health•2026

    A public health emergency operations centre (PHEOC) is a hub for effective coordination of information and resources. Countries have established PHEOCs as part of the effort to strengthen their emergency management capabilities. However, there is limited documented evidence of best practices in PHEOC implementation in accordance with the world health organization PHEOC framework. A survey was conducted to document best practices and experiences i…

  • Covid-19 mortality rate and its associated factors during the first and second waves in Nigeria

    Open Access•Kelly Elimian, Anwar Musah et al.•ARTICLE•PLOS Global Public Health•2022

    COVID-19 mortality rate has not been formally assessed in Nigeria. Thus, we aimed to address this gap and identify associated mortality risk factors during the first and second waves in Nigeria. This was a retrospective analysis of national surveillance data from all 37 States in Nigeria between February 27, 2020, and April 3, 2021. The outcome variable was mortality amongst persons who tested positive for SARS-CoV-2 by Reverse-Transcriptase Poly…

  • Epidemiological description of and response to a large yellow fever outbreak in Edo state Nigeria, September 2018 - January 2019

    Open Access•E Nwachukwu William, John Oladejo et al.•ARTICLE•BMC Public Health•2022

    Edo State is one of the states in Nigeria with the highest burden of yellow fever. More males were affected among the confirmed. Major symptoms include fever, jaundice, weakness, and bleeding. Majority of surveillance performance indicators were above target. There is a high risk of transmission of the disease in the state. Low yellow fever vaccination coverage, and presence of yellow fever vectors (Ae.aegypti, Ae.albopictus and Ae.simpsoni) are …

  • Building local capacity for emergency coordination

    Open Access•Oyeronke Oyebanji, Fatima Ibrahim Abba et al.•ARTICLE•BMJ Global Health•2021

    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…

  • Epidemiological comparison of the first and second waves of the Covid-19 pandemic in Nigeria, February 2020–April 2021

    Open Access•Oluwatosin Akande, Kelly Elimian et al.•ARTICLE•BMJ Global Health•2021

    BACKGROUND: With reports of surges in COVID-19 case numbers across over 50 countries, country-level epidemiological analysis is required to inform context-appropriate response strategies for containment and mitigation of the outbreak. We aimed to compare the epidemiological features of the first and second waves of COVID-19 in Nigeria. METHODS: We conducted a retrospective analysis of the Surveillance Outbreak Response Management and Analysis Sys…

SARS-CoV-2 is \nlikely of zoonotic origin, similar to SARS and Middle East Respiratory Syndrome (MERS), and transmitted between humans through respiratory droplets and fomit…
