What is the difference between a "pharynx swab positive" and a newly crowned confirmed case?

June 13, Beijing held the 114th regular press conference on epidemic prevention and control, in response to the new outbreak in Beijing's new market, the Beijing Municipal and District Centers for Disease Control and Prevention on June 12, the market for new coronavirus nucleic acid testing, found 40 environmentally positive samples;
, what exactly does "pharynx swab positive" mean; what is the difference between a pharyngophal swab-positive and a newly crowned confirmed case; and how do people who are currently positive for pharynx swab be isolated?" encountered this new coronary pneumonia outbreak, pharynx swab collection is currently china's main detection method for viral nucleic acids. If the pharynx swab is positive, it means that the nucleic acid is positive, indicating that the 45 people carry the new coronavirus. A well-known immune system expert told reporters.
does it mean to test positive for nucleic acid? It is reported that the coronavirus is composed of protein and RNA, RNA is responsible for the reproduction of the virus, protein outside, both to maintain the particle form of the virus, but also to protect the internal RNA. Therefore, nucleic acid testing is a direct detection of the presence of the virus at present, that is, pharynx nucleic acid positive represents the presence of the virus in the body.
the new coronavirus is mainly transmitted through the respiratory tract, the pharynx is where such viruses gather more. This is done by using medical cotton swabs to extract a small amount of secretion from the body's pharynx and then test the specimens.
the above-mentioned experts told reporters, to determine that infected people generally need to do two or more pharynx swab testing, two pharynx swabs positive to be considered infected, two sampling interval of 24 hours. Two nucleic acid tests for pharynx negative is also an indicator of discharge from the hospital." Pharynx swab nucleic acid positive may be an asymptomatic infected person or a confirmed case of neo-crown pneumonia," said
Cheng Chengshun, director of the Respiratory and Critical Medicine Department of Wuhan University Central South Hospital and director of the respiratory branch of Wuhan Medical Association, while pharynx swab-positive does not mean a confirmed case of neocooprosis.
Cheng Chengshun explained, "If the subject is positive for pharynx swab nucleic acid, but does not have clinical symptoms, such as fever, breathing difficulties, etc., and the lung CT does not show significant manifestations of viral infection, then it is called asymptomatic infection."
Cheng Added that according to the description of the diagnostic criteria for confirmed cases of neo-coronary pneumonia in the New Coronavirus Pneumonia Diagnosis and Treatment Program (Trial 7th Edition), whether or not the confirmed cases need to be combined with clinical manifestations and other test results such as lung CT after the subjects tested positive for nucleic acid. Only those who meet the diagnostic criteria for neo-crown pneumonia can be said to be confirmed cases.
" from the recent findings in Wuhan, asymptomatic infected people are very weak infectious, but asymptomatic infected people have the possibility of became symptomatic, so the need for unified isolation observation. Generally speaking, asymptomatic infected people can not be treated with special treatment when observed in isolation. Cheng Jinshun went on.
