Generally, patients with CKP will not infect others after becoming negative, because a negative nucleic acid test result means that there is no more CKP virus in the body, and it is not infectious any more. However, there is still a possibility that a patient with C.N.C.P. may become reinfected or reinfected after treatment, in which case he/she can infect others.
1. Reactivation: After some patients with CKP are cured, they may experience reactivation. This means that the virus is present in the body and it is contagious. However, the chances of re-positive are relatively low, and the contagiousness is also relatively small.
2. Reinfection: After the new coronary pneumonia patient turns negative, it is possible to be infected with the new coronary virus again, which is also contagious and can be transmitted to the surrounding people.
During the epidemic, even if the patient has turned negative, he still needs to do a good job of personal protection, regular nucleic acid testing, and review the recovery status of the body.
