Abstract

Cumulative COVID-19 daily new cases dataset during January to April, 2020 were used to search for evidences of SARS-CoV-2 spreading patterns (transmission forms) in the geographical regions with samples of Asia, South America, North America, Middle East, Africa and European countries. In order to comprehend the cause of constant infection rates for some countries, while others present very low daily new cases (China and South Korea), this research investigated possible aerosols forming patterns in the atmosphere and its relation to policy measures adopted by selected countries.
