The most recently detected anthropozoonotic coronavirus (COVID-19) is a strain that began infecting humans in December 2019, following the reported outbreak of unexplained pneumonia in Wuhan, China. COVID-19 infection can pass from human to human via droplets showing mild (in 80% of cases), moderate or severe illness (in 20% of cases, with 6% of them requires special mechanical ventilation) with multiple organ failure and death. The difference in the disease severity where some people may appear with severe and life-threatening COVID-19 sequelae whereas the others may appear asymptomatic or even with mild symptoms directed us to focus the light on the genome structure and the different genotypes of COVID-19 with regarding the possible risk factors of acquiring the infection in humans (such as: age, gender, occupation, smoking, obesity, pregnancy, race and economic status, alcohol consumption, food consumption, immunological status, residence, travel, contact with pets), animals (such as: species and age), environment (season) and the viral agent itself (such as: infectivity dose and virulence) to be considered during the expected rise of the third wave of COVID-19.
