Rapid and reliable detection of severe acute respiratory syndrome coronavirus 2 mutations are significant to control the contagion and spread rate of the virus. We aimed to evaluate the N501Y mutation rate in randomly chosen positive patients with the polymerase chain reaction (PCR). The evaluation and analysis of the data with a retrospective approach in cases with mutations, in terms of public health, will contribute to the literature on the global pandemic that affects our society. Public health authorities will take the necessary precautions and evaluate the current situation. The N501Y mutation was detected in patients with positive Covid-19 PCR test results. The positive samples were examined based on the 6-carboxy-fluorescein (FAM) channel in reverse transcription PCR (RT-PCR) quantitation cycle (Cq) values as low Cq (<25), medium Cq (25-32), and high Cq (32-38) groups. In the study, 2757 (19.7%) of 13 972 cases were detected as mutation suspects and 159 (5.8%) of them were found to have mutations. The ages of the cases with mutations ranged from 1 to 88 years (mean age of 40.99 ± 17.55). 49.7% (n = 79) of the cases with mutations were male, and 50.3% (n = 80) were female. When the RT-PCR-Cq results were examined, it was seen that it varied between 11.3 and 35.03, with an average of 20.75 ± 3.32.
快速可靠地检测严重急性呼吸综合征冠状病毒 2 突变对于控制病毒的传播和传播速度非常重要。我们旨在通过聚合酶链反应(PCR)随机选择阳性患者来评估 N501Y 突变率。从公共卫生角度对突变病例进行回顾性评估和分析,将有助于我们了解影响我们社会的全球大流行。公共卫生当局将采取必要的预防措施并评估当前局势。N501Y 突变在新冠病毒 PCR 检测结果呈阳性的患者中被检测到。根据逆转录 PCR(RT-PCR)定量周期(Cq)值中低 Cq(<25)、中 Cq(25-32)和高 Cq(32-38)组,对阳性样本进行检查。在该研究中,13972 例病例中有 2757 例(19.7%)被检测为突变疑似病例,其中 159 例(5.8%)被发现存在突变。突变病例的年龄范围为 1 至 88 岁(平均年龄为 40.99±17.55 岁)。突变病例中,49.7%(n=79)为男性,50.3%(n=80)为女性。当检查 RT-PCR-Cq 结果时,发现其在 11.3 到 35.03 之间变化,平均值为 20.75±3.32。
