According to a study of the US National Health Research Institute (NIH), the new crown virus SARS-COV-2 can propagate almost all organ systems including the heart, the brain within a few days, and Savory for a few months.

SARS-COV-2, "severe acute respiratory syndrome coronary virus 2", the disease caused by the virus is called new crown pneumonia (COVID-19).

The results show that if the virus is not removed in time, the patient is likely to lead to a long-term sequelae (long Covid). The author said that understanding the persistent mechanisms of viruses, as well as the response of the human body to the virus library, is expected to help improve new crown treatment.

NiH scientists said that this is the most comprehensive analysis of the distribution and persistence of SARS-COV-2 virus in human and brain so far.

Compared with their autopsy, the NIH team's autopsy is usually carried out about a day after the death of patients, and the organization is more comprehensive.

Researchers also use various tissue storage techniques to detect and measure viruses, and cultivate a virus collected from the first week of patient death (including lung, heart, small intestine and adrenal).

The author said: "Our research results show that although the respiratory tract and lungs are affected by new crown viruses, the virus can be propagated in the early stage of infection and infecting the entire human body, including infection of the whole brain."

However, these discovery and use technologies have not been reviewed by independent scientists.

"This is a very important work", Missouri veterans' St. Louis Health Care System (Veterans Affairs St.Louis Health Care System) Clinical Epidemiology Center Director Ziyad Al-aly.

"For a long time, we have always touched the mind, and it is unclear why the new crown long-term sequelae has affects so many organ systems. This paper provides some inspirations and may help explain why even if there is mild or asymptomatic Long-term symptoms will also occur in people of acute diseases. "

Raina Macintyre, a Professor of Global Biosafety University, Sydney, said that the pathological data provided by this study supported the previous research results, for example, the new crown will directly kill myocardial cells, and those who survive in infection will recognize Knowing defects.

However, new crown virus infection respiratory tract and petroplasmic cells have caused part of some of the industry insiders.

NiH 's research is based on the samples and analysis of the 44 new crown caused by the first year of the epidemic, and does not involve long-term symptoms.

Daniel Chetow, head of the emerging pathogen, said that there is no good explanation that respiratory tract infections and the time required to remove viruses from infected tissues (especially brain).

The study team detected RNA of the new crown virus that persisted in multiple parts (including the entire brain) in patients with symptoms or 230 days. They guess that this may mean infecting defective viral particles.
