Models for COVID-19 Daily Confirmed Cases in Different Countries

In this paper, daily confirmed cases of COVID-19 in different countries are modelled using mathematical regression models. The curve fitting is used as a prediction tool for modeling both past and upcoming coronavirus waves. According to virus spreading average annual temperatures, under study classified into three main categories. First category, the first wave takes about two-year seasons (about 180 days) complete viral cycle. Second one-year season 90 cycle with higher rate. These take stopping periods low Third that highest rate without periods. Finally, predictions scenarios made compared actual current smoothed these countries.
