The severe acute respiratory syndrome coronavirus-2 is a highly communicable disease that emerged in the twilight of 2019 in Wuhan, China but rapidly spread globally, resulting in a pandemic. Given its novelty, scientific information about its origin, biology, spread and preventive measures trickled over time, which could have been responsible for the successful global spread. In this paper, relevant literature related to the spread of the disease was reviewed. A list of factors associated with the successful spread among the human population was documented and the challenges with public health surveillance systems and the lessons learnt were highlighted.
Key words: Covid-19, coronavirus-2 (SARS-CoV-2 virus), pandemic, surveillance, zoonosis.
