    Snippet: The positive rate of the first throat swabs real-time RT-RNA test in patients was 66%; the cumulative positivity rate in two rounds was 86%, and the cumulative positivity rate in three rounds was 96%. Therefore, the sensitivity of virus RNA test as the main diagnostic method is not high, could be due to the low viral load in upper respiratory tract [20, 21] . In the absence of more sensitive diagnostic methods, we recommend ≥3 repeated molecula.....
    Document: The positive rate of the first throat swabs real-time RT-RNA test in patients was 66%; the cumulative positivity rate in two rounds was 86%, and the cumulative positivity rate in three rounds was 96%. Therefore, the sensitivity of virus RNA test as the main diagnostic method is not high, could be due to the low viral load in upper respiratory tract [20, 21] . In the absence of more sensitive diagnostic methods, we recommend ≥3 repeated molecular tests to increase the diagnostic rate, in order to effectively control transmission.
