                    Snippet: Specifically, a test result with a cycle threshold value (Ct-value) ≤ 38 and a significant amplification curve was defined as positive. And a negative result was defined with a Ct-value > 38. Retesting was required in cases other than those mentioned above. Besides, negative cases were double checked by re-sampling and retesting with an interval as 24 h, and could be confirmed when negative results were obtained in 2 consecutive tests......
