Abstract
The mention of the COVID-19 waves is as prevalent as the pandemic itself. We scientifically identify waves and the breaking points at which they begin and end from the beginning of the pandemic till June 2021. We use the Break Least Square method to determine the significance of COVID-19 waves for global-, regional-, and country-level data. The results show that the method works efficiently in detecting different breaking points. Identifying waves at the country level is more relevant than global or regional levels. Once it begins, and irrespective of the circumstances, the COVID-19 wave takes about 48 days on average to subside. Identifying the correct breaking points is critical to evaluate the impact of various COVID-19 variants and the different pharmaceutical and non-pharmaceutical interventions.
