New Express News reporter: Will the Provincial Center for Disease Control and Prevention, re-examination of patients with positive nucleic acid in the discharged patients, re-infected with new crown pneumonia? Is this "Fuyang" contagious?
And our province actually has preliminary data, and 14% of the patients who are discharged now also have the phenomenon of "rejuvenation".
We all know that pneumonia is a relatively long-lasting disease, and it may take two or three months to recover. Recently, Academician Zhong Nanshan also said in the media that some elderly people or some are in poor physical condition. His pneumonia recovery is Slower, this process is similar to tuberculosis, some people may appear active, and some people may recover.
We observe new coronary pneumonia, a similar situation may occur, but we are gradually going to scientific evidence-based, and have not yet reached a systematic scientific conclusion.
We also monitored it in the laboratory and found that young mild patients will soon develop antibodies within two weeks. If they are positive, his risk is actually very low. We think he is a protective antibody. He The risk of transmission is getting lower.
However, there are some elderly people who find that it takes a long time to produce antibodies. It may take a long time to produce antibodies. He will continuously detoxify and may become a source of infection.

Antibody-dependent enhancement (ADE) occurs when antibodies facilitate viral entry into host cells and enhance viral infection in these cells.
A neutralizing antibody binds to the surface spike protein of coronaviruses like a viral receptor, triggers a conformational change of the spike, and mediates viral entry into IgG Fc receptor-expressing cells through canonical viral-receptor-dependent pathways.
Re-use refers to the practice of using the same N95 respirator by one HCP for multiple encounters with different patients but removing it (i.e. doffing) after each encounter. This practice is often referred to as “limited reuse” because restrictions are in place to limit the number of times the same respirator is reused. It is important to consult with the respirator manufacturer regarding the maximum number of donnings or uses they recommend for the N95 respirator model. If no manufacturer guidance is available, data suggests limiting the number of reuses to no more than five uses per device to ensure an adequate safety margin.1 N95 and other disposable respirators should not be shared by multiple HCP. CDC has recommended guidance on implementation of limited re-use of N95 respirators in healthcare settings.
To maintain the integrity of the respirator, it is important for HCP to hang used respirators in a designated storage area or keep them in a clean, breathable container such as a paper bag between uses. It is not recommended to modify the N95 respirator by placing any material within the respirator or over the respirator. Modification may negatively affect the performance of the respirator and could void the NIOSH approval.
The patient, whose name wasn't released, was elderly and had underlying health conditions, and probably was exposed to the virus on a cruise from February 11 to 21 between San Francisco and Mexico, Placer County health officials said. A person from Sonoma County who was on the cruise has contracted the virus.
