COVID-19 mortality rate and its associated factors during the first and second waves in Nigeria.

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.

Risk communication during health emergencies in Nigeria: What are its challenges?

Although globalization has been advantageous in facilitating the free movement of people, goods, and services, the ease of movement of cross-border pathogens has increased the risk of international public health emergencies in recent years. Risk communication is an integral part of every country's response during public health emergencies such as the coronavirus disease (COVID-19) pandemic. To effectively increase adherence to guidelines during health emergencies, it is essential to understand the impact of social, cultural, political, and environmental factors on people's behaviours and lifestyles in any given context, as well as how these factors influence people's perception of risks.

Perceived risk and protective behaviors related to COVID-19 among the Nigerian general population: An application of the extended parallel process model.

Since the outbreak of the coronavirus disease 2019 (COVID-19), there have been heightened levels of fear worldwide. The steadily increasing number of COVID-19 cases in Nigeria as reported by the Nigerian center for Disease Control has led to different behavioral responses influenced by perceived threat and efficacy. This study aimed to understand the levels of perceived threat and efficacy to COVID-19 in Nigeria across various demographic groups using the Extended Parallel Process Model.

Implementing an emergency risk communication campaign in response to the COVID-19 pandemic in Nigeria: lessons learned.

At the onset of the COVID-19 pandemic, the WHO recommended the prioritisation of risk communication and community engagement as part of response activities in countries. This was related to the increasing spread of misinformation and its associated risks, as well as the need to promote non-pharmaceutical interventions (NPIs) in the absence of an approved vaccine for disease prevention. The Nigeria Centre for Disease Control, the national public health institute with the mandate to prevent and detect infectious disease outbreaks, constituted a multidisciplinary Emergency Operations Centre (EOC), which included NCDC staff and partners to respond to the COVID-19 outbreak.

Hepatitis B and C seroprevalence among residents in Lagos State, Nigeria: A population-based survey.

Background: Hepatitis is one of the leading causes of morbidity and mortality, particularly in developing countries. It is often caused by hepatitis B and C, which are both preventable and treatable. Available information on Hepatitis B and C in Nigeria is based primarily on estimates obtained from specific population sub-groups or hospital-based surveys leaving gaps in population-level knowledge, attitudes, and prevalence.

Public risk perception and behaviours towards COVID-19 during the first and second waves in Nigeria: a secondary data analysis.

Objectives: To describe changes in public risk perception and risky behaviours during the first wave (W1) and second wave (W2) of COVID-19 in Nigeria, associated factors and observed trend of the outbreak.

Design: A secondary data analysis of cross-sectional telephone-based surveys conducted during the W1 and W2 of COVID-19 in Nigeria.

Setting: Nigeria.

Epidemiological comparison of the first and second waves of the COVID-19 pandemic in Nigeria, February 2020-April 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 System data of the first and second epidemiological waves, which were between 27 February and 24 October 2020, and 25 October 2020 to 3 April 2021, respectively.

Descriptive epidemiology of coronavirus disease 2019 in Nigeria, 27 February-6 June 2020.

The objective of this study was to describe the epidemiology of COVID-19 in Nigeria with a view of generating evidence to enhance planning and response strategies. A national surveillance dataset between 27 February and 6 June 2020 was retrospectively analysed, with confirmatory testing for COVID-19 done by real-time polymerase chain reaction (RT-PCR). The primary outcomes were cumulative incidence (CI) and case fatality (CF).

Performance of the Public Health System During a Full-Scale Yellow Fever Simulation Exercise in Lagos State, Nigeria, in 2018: How Prepared Are We for the Next Outbreak?

Recurring outbreaks of infectious diseases have characterized the West African region in the past 4 decades. There is a moderate to high risk of yellow fever in countries in the region, and the disease has reemerged in Nigeria after 21 years. A full-scale simulation exercise of the outbreak of yellow fever was conducted to assess preparedness and response in the event of a full-scale outbreak.

Trend and determinants of tuberculosis treatment outcome in a tertiary hospital in Southeast Nigeria.

Introduction: Nigeria ranked 7th among the high TB burden nations globally and second most endemic in Africa. There are several highly effective interventions available for tuberculosis control. Operational challenges have been reported to interfere with the success of these interventions.

Outbreak of human monkeypox in Nigeria in 2017-18: a clinical and epidemiological report.

Background: In September, 2017, human monkeypox re-emerged in Nigeria, 39 years after the last reported case. We aimed to describe the clinical and epidemiological features of the 2017-18 human monkeypox outbreak in Nigeria.

Methods: We reviewed the epidemiological and clinical characteristics of cases of human monkeypox that occurred between Sept 22, 2017, and Sept 16, 2018.

Reemergence of Human Monkeypox in Nigeria, 2017.

In Nigeria, before 2017 the most recent case of human monkeypox had been reported in 1978. By mid-November 2017, a large outbreak caused by the West African clade resulted in 146 suspected cases and 42 laboratory-confirmed cases from 14 states. Although the source is unknown, multiple sources are suspected.
