INTRODUCTION
A pandemic ensues once an infectious disease goes global. The consequence is that high morbidity and mortality stems off because the response rate due to poor preparedness is low and considerably insufficient to ensure containment and prevention, these limitations especially with healthcare measures being inadequate and insufficient means that the situation will progress for a considerable length of time and through the years, several pandemics have taken place notably; the bubonic plaque, yellow fever, SARS CoV-1 and currently SARS CoV-2 (Lu et al., 2019; Guarner, 2020; Zhou et al., 2020).
As the outbreak continued to spread out at a remarkable pace, the World Health Organization (WHO) had to declare it a pandemic on March 11, 2020. SARS-CoV-2 is the seventh coronavirus to infect humans and the causative agent for COVID-19. Previously, two coronavirus epidemics raised international concern, SARS in 2002–2003 and MERS in 2012. As for the new virus, it is highly infectious and has already killed over 200,000 people with an estimated sCFR (symptomatic case fatality risk) of 1.4% (0.9–2.1%). By comparison, fatality due to SARS was roughly 10%, whereas, for MERS, it was as high as 35%, making it one of the deadliest human pathogens. However, SARS-CoV-2 has been shown to have much higher human-to-human transmissibility. With the ability to infect people through asymptomatic carriers, it can remain unnoticed and quickly disseminate itself, making the disease containment a confounding public health challenge (Velavan et al., 2020; Guarner, 2020; Zhou et al., 2020)
