| Summary: | The pandemic COVID-19 is caused by a highly transmissible severe acute respiratory coronavirus 2 (SARS-CoV-2) which showed the highest morbidity and mortality rates among the other coronavirus infections such as SARS-CoV and MERS-CoV. However, the numbers of infected cases as well as mortality rates are varying from population to population. Therefore, scientist has urged the SARS-CoV-2 genome and host genetic factors investigations. Recently, new SARS-CoV-2 variants has been detected and though to affect the diseases transmission from human to human. In this mini-review, we aimed to explained detected SARS-CoV-2 variants that thought to influence the COVID-19 severity and transmission using the literature.
