| Abstract | ||
| Coronavirus (COVID-19) infection has spread widely around the world, affecting individuals of various age groups and both sexes, particularly those with chronic diseases. The severity of the illness is associated with sex, age group, and certain chronic conditions such as obesity, hypertension, diabetes, heart and arterial disease, and chronic kidney disease. This study aimed to identify risk factors, including sex, age group, smoking, and prevalent chronic diseases (specifically hypertension, diabetes, and obesity), and their association with increased severity of COVID-19. Data were collected from 160 patients confirmed to be infected with COVID-19 during the period from July 1, 2024, to October 30, 2024. COVID-19 was more severe in patients aged 51 years and older, accounting for 56% of cases. Males were more severely affected than females, with 57% of male patients compared to 40% of female patients. The disease was more severe in individuals with comorbidities, specifically: hypertension (93%) and diabetes (90%), compared to those without chronic disease. Additionally, obesity had a significant impact on COVID-19 severity, affecting 52% of patients compared to those with a normal weight. Among smokers, the severity of COVID-19 was reported at 89% compared to non-smokers. | ||
