New coronavirus could also cause damage to asymptomatic people, study says

One of the difficulties in the prevention and control of the new crown virus is that it is anasymptomatic infected with a certain infectiousness. In addition, even if patients cannot perceive their infection, the new coronavirus can still cause harm to their bodies. Blood and CT tests, for example, reveal that the body is fighting infection with the SARS-CoV-2 virus. A lesions consistent with COVID-19 pneumonia and mild damage to the immune system are shown.

In order to control the spread of the new crown virus, the international consensus on the wearing of personal protective equipment such as masks, as well as the maintenance of social alienation and other policy consensus. But for asymptomatic people, it is clearly difficult for epidemic prevention agencies to urge them to undergo testing or short-term isolation.

A few days ago, officials of the World Health Organization (WHO) spoke about asymptomatic people.

Fortunately, on the advice of experts such as Dr. Fuchs, the agency has corrected the guidelines, making it clear that asymptomatic people may also have a higher ability to transmit.

Community surveys have found that even seemingly healthy individuals may detect evidence of a history of resistance to infection in their bodies during later blood and CT screening.

According to a paper published in the Journal of the American Medical Association (JAMA) by Wuhan researchers:

After comparing the clinical characteristics of patients with asymptomatic and asymptomatic COVID-19, the scientists found that the latter performed significantly better than the former.

The loss of CD4 and T lymphocytes in asymptomatic infected people indicates that the damage to the immune system from such infections is relatively low.

Even so, asymptomatic infections with less severe injuries may not realize they are carrying the new coronavirus.

During the absence of isolation or seeking treatment, symptoms are ignored by health care providers and the disease is unknowingly transmitted to others.

The study noted that patients with asymptomatic liver damage had a lower rate than patients with symptoms and showed faster recovery of lung function in CT scans.

This means that their body (the lungs themselves) is fighting infection, and the SARS-CoV-2 virus has been replicated to a certain extent in their bodies.

That way, a CT scan can identify potential viruses or hide where to breed, even if there is no cough or breathing difficulties.

A few days ago, Hong Kong researchers published a new article in The Lancet that reviewed the distribution (spread) and serum transformation of the new crown virus on the Diamond Princess cruise ship.

It was found that asymptomatic patients also developed lung damage consistent with COVID-19 infection, and a change in glass “consistent with interstitial pneumonia” was observed in a high-resolution CT scan, leading to the conclusion that asymptomatic people carrying the virus as well.

A third study, published in The Lancet, analyzed the clinical characteristics of 104 people on the same cruise ship.

Results 33 cases were asymptomatic over the entire observation period. At first only 10 people were considered asymptomatic, but developed symptoms during follow-up observation.
