Why is it not uncommon for the "new crown Fuyang"? MIT Thriller Study: Viruses and DNA Combine!

Countries around the world to coordinate the fight against the epidemic, some countries have achieved "war epidemic" results, basically restored to life, but also more and more new crown patients out of the hospital, live a normal life.
, however, the new coronavirus is cunning, some patients have been cured, but there has been a "fuyang" situation, and some rehabilitation will appear "secondary infection."
so-called "fuyang", usually refers to the new crown rehabilitation of the nucleic acid test positive phenomenon.
since the outbreak, the media frequently reported the "new crown Fuyang" caused public concern, what is going on? Why is fuyang happening? A controversial MIT study has argued that the reason for the new coronary rehabilitation is that, excluding detection errors, there are several possibilities, one is that the body has been lurking viruses in tissues and cells, they are only temporarily suppressed by the immune system when the patient is discharged from the hospital.
the hospital, patients due to low immunity, unable to resist the virus's continued attack, resulting in the virus will come out again "activity", so that the nucleic acid positive situation reappeared.
is that after a patient is discharged from the hospital, the virus carried deep in the lungs cannot be detected by conventional testing.
is also the case that some patients' fuyang test results come from swabs, which the study believes is caused by slow antibody production and low levels, resulting in a delay in the removal of gastrointestinal viruses.
recently, a study by the Massachusetts Institute of Technology (MIT) raised another possibility of "fuyang" for new coronars.
the study, published on the preprinted platform bioRxiv, argues that the new coronavirus RNA can be reversed and integrated into the human genome.
common point, the virus is hidden by combining itself with human DNA through reverse transcription.
retrovirus is the equivalent of a virus hijacking a host and turning itself into part of the host's body.
The study is thought-provoking and immediately controversial, such as the fact that, if reliable, common flu may also alter human genes, but there is no medical evidence that influenza virus genes are integrated into the human genome.
addition, there are not many reverse transcriptases in human cells, and the study is actually more biased toward a "hypothesis" that is more different from the actual situation.
, there isn't much evidence that the new coronavirus is integrated into the DNA, so keep a "trust and doubt" attitude.
patients are prone to reyang after treatment? Is Fuyang patients contagious? How to deal with the new coronavirus Fuyang? At present, Fuyang situation is still an isolated phenomenon, Beijing Chaoyang Hospital Vice President Tong Zhaoxuan in the "News 1 and 1" said that the patient Fuyang and a human body, the disease is related to the severity of the body, the physically weak, serious patients have a greater probability of reyang.
fuyang patients infectious? This is a problem that many people are worried about.
Sun Yat-sen University affiliated with the third hospital infectious diseases department chief physician Lin Yuliang in August last year in an interview with the media, said that the nucleic acid test positive indicates that there is a virus in the body, as long as there is a virus replication, there is infectious, but the level of infectiousness depends on the amount of the virus.
, only Guangdong Health Anderse has publicly expressed the expert consensus on Fuyang patients - "low risk of transmission."
All in all, in order to deal with the new crown Fuyang, we must pay attention to, not to be taken lightly, in addition to strict isolation and treatment according to infectious disease isolation measures, but also should actively do a good job of close monitoring, in order to see the "face" of the new crown virus, for the "new crown of resistance" to provide valuable experience.
