Isea Raúl, What Could Represent the Mantissa of the Registered Covid-19 Cases?, International Journal of Coronaviruses, Volume 4, Issue 2, 2022, Pages 1-6, ISSN 2692-1537, https://doi.org/10.14302/issn.2692-1537.ijcv-22-4108. (https://oap-researcharticles.org/ijcv/article/1783) Abstract: In this work we present how it is possible to visualize the different coronavirus outbreaks from the calculation of the mantissa from the daily record of cases by Covid-19.This curve can also indicate the speed of propagation of the disease from the calculated infection rate. These conclusions are derived from the respective calculations in four different countries: Australia, Brazil, Italy, and Venezuela. Keywords: Mantissa; Covid-19; Infection rate; Outbreaks
