COVID-19 in Nigeria: Nipping Current Surge in Infections

The Nigeria Centre for Disease Control (NCDC) has continued to intensify efforts in ensuring timely epidemic intelligence gathering for evidence-based public health actions particularly in the control of the ongoing coronavirus disease (COVID-19) pandemic. In line with this, the 42nd edition of our Weekly Epidemiological Report (WER) highlighted the need for the public to continue to comply with all recommended infection prevention and control measures. This advice became more important given the soaring of cases (second wave) of COVID-19 across countries in Europe, the Middle East and the United States of America etc. However, it is increasingly worrisome that in recent times the second wave has now extended to other continents including Africa.

Over the past few weeks, there has been a sudden increase in the number of confirmed cases in different parts of Nigeria. As at December 16, 2020, there were 75,062 confirmed cases with most cases occurring from week 44 till date 16th December. 2020 (13,136 cases). This has left many with questions begging for answers. Are we now testing more? Is the general public not complying with the recommended infection prevention and control (IPC) measures? Any possible importation of cases? etc. While many of these public concerns are continuously being addressed by our diverse proactive public health measures, one likely explanation to the current situation is that there has not been sustained strict compliance in some settings with the recommended IPC measures.

As the yuletide approaches, it may be inevitable to witness situations such as frequent movement of people and population mixing. Given this, the public is therefore advised to limit travels as much as possible to essential ones. Strict compliance with all recommended infection prevention and control guidelines is strongly recommended to reduce the spread of COVID-19. These include the use of masks and maintaining physical distancing of at least 2 metres from others in public spaces. It is also important to avoid large gatherings and ensure to wash hands regularly under running water or alternatively, use an alcohol-based hand sanitiser where soap or water is not available.

If you notice symptoms of COVID-19, immediately call your state hotline for information on the nearest sample collection site. We urge Nigerians to continue to take responsibility by complying with the afore listed measures as recommended by the Federal Government of Nigeria. Our ability to overcome the current pandemic and nip the second wave of infections in the bud depends largely on our collective efforts.
