Recently, the world's top scientific magazine "nature" published an article. The core content is that the new coronavirus can replicate in the non-respiratory system of the human body except the respiratory system, such as the brain, heart, blood vessels , gastrointestinal tract, and even spinal cord , ganglia , and may survive in the above-mentioned organs and tissues for up to 7 months.
It sounds a bit scary [crying] Whether we do antigen testing or nucleic acid testing , we all detect the viral load in the upper respiratory tract. If the test is negative, only the virus in the upper respiratory tract is cleared, because the new coronavirus in the respiratory tract is cleared the fastest. We cannot detect viruses hidden in other organs and tissues.
Then why do the initial symptoms of new coronavirus include headaches, dizziness, muscle aches, gastrointestinal reactions, etc., but disappear later? I think it may be that after the body's immune fights, the remaining virus has lost a lot of its replication function. The virus cannot replicate, which means that the viral load is limited to a certain range, and the body will not be subject to large-scale immune stress, so it will not show the obvious symptoms at the beginning of the infection.
It is also worth noting that the research subjects of the Nature magazine paper were severe COVID-19 patients who had not been vaccinated. It is not yet clear whether the virus will continue to survive in the body for 7 months in mild patients. But judging from the "sequelae" of people around them after recovery, it should be true that the virus continues to survive in the body.
