Weekly Epidemiological Report

June 2021 Week 23



Posted: 05-07-2021 10:50:01 AM

Nigeria is one of the countries responding to the ongoing COVID-19 pandemic. This is being operationally led by the Nigeria Centre for Disease Control (NCDC) with the Presidential Steering Committee on COVID-19 providing the needed political and steering support. Given the novelty of the virus, one of the key priority areas of response has been to improve knowledge through research activities and epidemiological studies. This is in addition to other key areas such as surveillance, laboratory, case management, risk communication, points of entry, infection prevention and control etc.

Through the NCDC’s research activities around COVID-19, we have been able to contribute to the current body of knowledge both at national and global levels. Studies have revealed many contributory factors to the high number of COVID-19 infection among Nigerians. The current level of control of COVID-19 outbreak in Nigeria can also be partly attributed to the continuous application of strategies based on scientific evidence. The implementation of non-pharmaceutical interventions (NPIs) has been a key driver of success in the control of COVID-19 outbreak globally. However, there have been variations in compliance to the NPIs in various countries of the world including Nigeria. Understanding the wider ecological factors that influence people’s perception of risk, perception of public health interventions, and willingness and ability to adhere to the NPIs, is the core goal of the Data4COVID19 Africa Challenge project in Nigeria. The challenge is a data science project funded by l’Agence française de dévelopement (AFD) in partnership with Expertise France and The GovLab.

A call for proposal released in December 15, 2020, received 83 applications from 22 African countries out of which only 7 applications were selected for funding through a rigorous competitive process. Nigeria, through a collaboration between the NCDC and the College of Medicine, University of Lagos (CMUL) emerged one of the 7 awardees. The project seeks to reanalyse multiple non-traditional datasets collected at various phases of the COVID-19 outbreak to generate evidence to guide policy and practice in the control of the pandemic.

The NCDC-CMUL project titled “Understanding the facilitators and barriers to compliance with non-pharmaceutical COVID-19 preventive measures in Nigeria” was launched through an inception meeting held in Transcorp Hilton on June 25, 2021. The meeting was well attended by various stakeholders such as the Nigerian Governors Forum, Federal Ministry of Health, Federal Ministry of Education, National Orientation Agency, College of Medicine, University of Lagos, World Health Organisation, United States Centres for Disease Control and Prevention, etc. The Guest of honour, Honourable Minister of State for Education, Dr Chukwuemeka Nwajiuba, performed the ceremonial unveiling of the project plaque and expressed government’s commitment to implement the research findings. The 6-month project seeks to address five key questions in Nigeria:

1. What are the social, economic and political drivers of people’s compliance with Federal Government of Nigeria’s stay home policy?

2. How does the financial realities of Nigerians influence their response to COVID-19 safety protocols?

3. What places are Nigerians likely to visit, irrespective of COVID-19 government’s stay home policy and how can such places be better organised to reduce infection risks?

4. What are the changes in public risk perception and risky behaviours through the phases (first and second waves) of the outbreak and the relationship between risky behaviours to the trend of COVID-19 infection?

5. How has government’s non-pharmaceutical initiatives (NPI) affected public trust in government and people’s compliance with safety protocols?

An important output from the inception meeting was the sensitisation of stakeholders and demand creation for the research outputs. The critical next step is to proceed with relevant data analysis as informed by important deliberations and inputs during the meeting. We are grateful to AFD for this partnership geared towards providing more in-depth knowledge on COVID-19.
