The incubation period of novel coronavirus infection is mostly detectable with nucleic acid testing, but a few patients may require multiple tests to confirm the diagnosis.
During the incubation period of neocoronavirus infection, if the number of neocoronaviruses invading the patient is relatively large, most of them can be detected when nucleic acid testing is done. If the number of novel coronaviruses in the patient is relatively small during the incubation period, a false-negative test result may occur when the nucleic acid test is not standardized and the quality of the sample collected is substandard.
If the nucleic acid test is negative the first time, but incubation is suspected, a new coronavirus nucleic acid test is required after a 24-hour interval to aid in the diagnosis. Prompt detection and isolation of the virus during the incubation period can help prevent transmission.
If new coronavirus infection is suspected but without obvious clinical symptoms, multiple, standardized nucleic acid tests are required under the guidance of a healthcare professional.
