Asymptomatic infection refers to the invasion of viruses or bacteria and other pathogens into the human body, the human body does not have the corresponding clinical manifestations, generally manifested as hidden infection, pathogen carry or latent period.
1. Occult infection: the pathogen invades the human body without any clinical symptoms or signs, but there is an immune response, and very few patients may turn into a carrier state.
2. Pathogen Carrying: Pathogen Carrying status means that the pathogen stays in the body after it enters the body, and there are no obvious clinical symptoms and signs, but the body is carrying the pathogen.
3. Latent period: the latent period refers to the pathogen into the human body after the infection can be limited, but the infection is not completely clear, this situation has become the latent period of infection.
For example, in the new coronavirus pneumonia, a part of the patients have no clinical manifestations, but the pathogenicity test is positive, this is the asymptomatic infected person, mainly through close contact and close close close and other key groups of people to infect. Suspected asymptomatic infections need to be isolated immediately, and at the same time for pathogenetic testing.
It is recommended to pay attention to the usual protection, wear a mask, less crowded places, if found in contact with the positive crowd, do not be negligent, timely reporting, active treatment, isolation, so as not to affect the health of others.
