The incubation period of infectious diseases and a negative nucleic acid test are also infectious.
Patients infected with the virus, negative in the incubation period, may be due to a relatively short period of time, so the body’s viral load is not much, so it is difficult to detect; there may also be a false-negative situation, because the positive rate of a nucleic acid test is not 100%, so at this time there is a certain degree of contagiousness.
The so-called incubation period of infectious diseases refers to the period of time from the patient’s infection with pathogens, bacteria and viruses until the emergence of clinical symptoms, different infectious diseases, incubation period is not the same, however, whether it is the incubation period or morbidity, as long as the body exists in the presence of viruses, there is infectious.
Therefore, in the incubation period of infectious diseases, it is also necessary to actively take preventive measures to avoid infecting others.
