Özet
In this study, the relationship between viral load, demographic characteristics, and disease information in 1007 (48.5%) patients with Delta variant (B.1.617.2), and 1070 (51.5%) patients with Alpha variant (B1.1.7) were investigated. We found that there was a significant difference in viral load between patients who died from the Alpha variant and those who were discharged (p < 0.05). Nevertheless, no significant difference was observed in patients with the Delta variant. The viral load in patients who died from the Alpha variant was significantly higher than those who were discharged (p < 0.05). The viral load was found to be higher in females in patients with the Delta variant, whereas it was very close in males and females in patients with the Alpha variant (p > 0.05). No significant difference was detected between the cycle threshold values (Ct) and disease severity. In terms of the mean Ct values, statistical differences were observed in patients with Delta and Alpha variants. The Alpha variant was found to have a higher viral load than the Delta variant. Furthermore, the Delta variant was found to be higher in the 40-year-old and under-age group than the Alpha variant, whereas the Alpha variant was higher in the groups over 40 years old. Although the rate of moderate and severe patients in the Alpha variant was found to be higher, the rate of mild survivors was found to be higher in the Delta variant. In conclusion, the increase in vaccination before the appearance of the Delta variant in our region may have influenced the viral load and clinical status of the patients.
