Multifractal behavior of SARS-CoV2 COVID-19 pandemic spread, case of: Algeria, Russia, USA and Italy

Here, the multifractal behavior SARS-CoV2 COVID-19 pandemic daily and death cases is investigated through the so-called Wavelet Transform Modulus Maxima lines (WTMM) method, data of daily and death cases available via the World Health Organization (WHO) database of Algeria, Russia, USA and Italy is analyzed. The obtained results show the multifractal behavior of the COVID-19 pandemic spread data with different spectra of singularities.
