Positive turned negativeTaking the example of the positive turned negative of the new coronavirus, there is a possibility of being infected when a patient who is positive for the new coronavirus turns negative after treatment.
This is because after infection with the new coronavirus, although the body will produce corresponding antibodies, but this protective antibody does not exist permanently. After the protective antibodies have disappeared, the body may become infected again if it comes into contact with an infectious agent again and the body’s immunity is low. Therefore, even if you have been infected with the novel coronavirus, it is still necessary to prevent the novel coronavirus infection.
Effective measures to prevent novel coronavirus infection are wearing masks and washing hands frequently, which can minimize the chance of novel coronavirus infection.
Since the main modes of transmission of the novel coronavirus are respiratory droplet transmission and direct contact transmission, wearing masks and washing hands frequently can effectively reduce the chance of infection through these two modes of transmission, thus effectively preventing re-infection with the novel coronavirus.
