Role of Precautionary Measures in Containing the Natural Course of Novel Coronavirus Disease

Background: The coronavirus disease (COVID-19) pandemic is spreading at an alarming rate. Several health authorities have implemented specific precautionary measures worldwide to combat the spread of the disease. The influence of these measures on tackling the spread of the disease remains to be elucidated. Therefore, this study aimed to assess the impact of precautionary measures to contain the COVID-19 outbreak. Methods: Data for this study were gathered from publicly available data sources such as the Worldometer and World Health Organization websites. The expected number of new cases is calculated using a mathematical formula to assess the difference between the observed and expected number of cases, thus indicating the impact of precautionary measures on the spread of COVID-19. Results: The preventive measures massively impacted the reduction of COVID-19 cases in Saudi Arabia from the expected number of 437,097 accumulated cases by May 4, 2020, to the observed number of 28,656 accumulated cases. Thus, the fatality rate is reduced from the expected 15,735 accumulated deaths by May 4 to 191 accumulated deaths. Conclusion: Precautionary measures adopted by the Saudi Arabian health authorities were evidently effective in controlling the spread and further burden of COVID-19.
