Abstract
In December 2019, the first cases of a viral pneumonia were

SARS-CoV-2. On February 11, 2020 the World Health
Organization (WHO) named the disease Coronavirus disease2019 (COVID-19) and declared it a global pandemic on
March 11, 2020. As the COVID-19 cases escalated, it became
a source of tremendous disruption of the lives and means of
livelihood of huge populations of people worldwide. The
pandemic continues to spread and the number of cases of
COVID-19 worldwide numbered a cumulative 22,034,395
with 776,801 deaths as at August 17, 2020. (Worldometer
COVID-19 Pandemic, 2020) Nigeria had recorded 49, 485
cases and 977 deaths by the said date while South Africa leads
the continent’s tally of the disease with 589,886 cases and
11,982 deaths – the fifth highest in the world. (Worldometer
COVID-19 Pandemic, 2020). The implementation of
measures instituted to limit the spread of the disease by most
national governments included wearing of face masks in
