This study investigated the demographic characteristics of 120 patients in the age range from 27 to 70 years old, without chronic disease, who were infected with COVID-19 and treated at Al-Hussein Teaching Hospital in Thi-Qar Province/Southern of Iraq. In this study, the male increased non-significantly than female 55.83% 44.17% respectively. The infected females had a higher BMI (29.1 ± 6.07kg/m2) than males (26.7 ± 5.99 kg/m2); 12.5% of the male patients and 0.83% of the female patients were previously infected with COVID-19; and 12.5% of the patients and 7.5% of female patients were previously vaccinated against COVID-19. The study noted a positive relationship between BMI and disease severity in both male and female patients and that males had a higher percentage of severe disease than females.
